摘要：
The material foundation of sustainable agricultural development is cultivated land resources, and their sustainable use is critical to fostering agricultural sustainability and guaranteeing national food security. In this paper, the multifunctional evaluation framework of the cultivated land system based on the "GESEL" model at the grid scale (5 km x 5 km) is constructed to explore the spatiotemporal evolution characteristics of a multifunctional cultivated land system in two lake plains and the trade-off and synergy between the functions. The five functions are all unstable in time scales, and their spatial distribution characteristics are also different. The trade-off and synergy between the multiple functions of the cultivated land system in the two lake plains from 2000 to 2019 showed significant spatial heterogeneity. Most of the functions were mainly collaborative, and a few were trade-offs. The two lake plains can be divided into four multi-functional cultivated land zones: a grain production leading zone, a distinctive agricultural planting zone, a high-efficiency agricultural development zone, and an ecological agricultural construction zone. This research puts forward some countermeasures and suggestions to promote the sustainable utilization of cultivated land resources.

摘要：
BACKGROUND: This study examined the extent to which the network structure of anxiety and depression among adolescents identified during the peak of the COVID-19 pandemic could be cross-validated in a sample of adolescents assessed after the COVID-19 peak. METHODS: Two cross-sectional surveys were conducted between February 20 and 27, 2020 and between April 11 and 19, 2020, respectively. Depressive and anxiety symptoms were assessed using the 20-item Center for Epidemiological Studies-Depression and 7-item Generalized Anxiety Disorder, respectively. Anxiety-depression networks of the first and second assessments were estimated separately using a sparse Graphical Gaussian Model combined with the graphical least absolute shrinkage and selection operator method. A Network Comparison Test was conducted to assess differences between the two networks. RESULTS: The most central symptoms in the first and second survey networks were Depressed affect and Nervousness. Compared with connections in the first survey network, connections in the second survey network analysis between Relax-Nervousness-Depressed affect-Interpersonal problems (diff, contrast: second survey-first survey. diff=-0.04, P=0.04; diff=-0.03, P=0.03; diff=-0.03, P=0.04), and Irritability-Somatic complaints (diff=-0.04, P=0.02) were weaker while connections of Somatic complaints-Nervousness (diff=0.05, P<0.001), Somatic complaints-Depressed affect (diff=0.03, P=0.009), and Irritability-Control worry-Restlessness (diff=0.02, P=0.03; diff=0.05, P=0.02) were stronger. CONCLUSIONS: Depressed affect emerged as a robust central symptom and bridge symptom across Anxiety-Depression networks. Considering the negative impact of depression and anxiety on daily life, timely interventions targeting depressed affect should be implemented to reduce the co-occurrence of anxious and depressive symptoms among adolescents during the COVID-19 pandemic.

摘要：
The agricultural ecological environment is the premise and foundation of rural economic development and the rural economy is an important manifestation of the vitality of the agricultural ecological environment. Taking 14 prefecture-level cities in Guangxi as the research object, this paper collects and sorts out the relevant data indicators of rural economy and agricultural ecological environment of them from 2007 to 2019, constructs the evaluation index system, calculates the development index by using the comprehensive index function, and finally uses an innovative digitization evaluation scheme to further evaluate the spatiotemporal coupling and coordination relationship between the rural economy and agricultural ecological environment. The following conclusions are ultimately drawn. First, the comprehensive level index of the rural economy shows linear growth with unbalanced regional development (values from 0.306 to 0.598). Second, the comprehensive index of the agricultural ecological environment shows fluctuating growth with obvious regional differences (values from 0.264 to 0.483). Third, the development of rural economy and agricultural ecological environment is not synchronized, and there is mutual influence. Fourth, the coordination level of the rural economy and agricultural ecological environment is low (coupling values from 0.369 to 0.513). Then, policy inspirations are proposed. First, the investment in agricultural science and technology innovation should be increased and the modern agricultural technology system. Second, agricultural industrial structure should be optimized and the agricultural industrial chain. Third, the construction of agricultural infrastructure should be improved, and the high-quality development of agriculture should be promoted. Fourth, the education of ecological civilization should be strengthened, and awareness of ecological and environmental protection should be established. Fifth, they should strengthen education and training and cultivate new professional farmers. Sixth, they should improve the utilization rate of land and enhance the arable land production capacity.(c) 2022 Published by Elsevier Espana, S.L.U. on behalf of Journal of Innovation & Knowledge.

摘要：
Based on the Tapio decoupling model, this paper discusses the decoupling relationship between the economic growth and carbon emissions of the manufacturing sector in southern Jiangsu, northern Jiangsu and middle Jiangsu during the 13th Five-Year-Plan period. By using the LMDI method, the carbon emissions and influencing factors of 31 subindustries of the manufacturing sector in Jiangsu Province from 2016 to 2020 were quantitatively analyzed by region and industry. The main findings are as follows: (1) during the 13th Five-Year-Plan period, the growth rate of the energy consumption and carbon emissions of the manufacturing sectors in southern Jiangsu, northern Jiangsu and middle Jiangsu slowed down, and the industrial structure was increasingly optimized; (2) economic growth is the primary driving force behind the manufacturing carbon emissions in the three regions of Jiangsu Province, while energy intensity is the main factor that affects the carbon-emission differences among the manufacturing subsectors in the different regions; (3) improving the energy efficiency of high-emission-intensity industries, such as the ferrous metal smelting and calendering industry, chemical industry and textile industry, is the key to reducing the carbon emissions of the manufacturing sector in the different regions of Jiangsu in the future. Jiangsu Province should promote the upgrading of the manufacturing-industry structure, and it should encourage the high-energy-consumption industry to reduce its energy intensity by technological innovation to achieve the goal of emission reduction and economic growth.

摘要：
Lodging has a negative effect on rice production and leads to a great loss in yield and quality. It is necessary to clarify the effects of straw return measures coupled with rice-duck co-culture on lodging and to explore a measure that can improve lodging resistance. A randomized block experiment with six treatments (rice monoculture (RNN), rice-duck co-culture (RND), direct straw return and rice monoculture (RSN), direct straw return coupled with rice-duck co-culture (RSD), straw carbon and rice monoculture (RBN), and straw carbon coupled with rice-duck co-culture (RBD)) was conducted to investigate the mechanism of the change in lodging resistance. RNN's rice yield was 6258.02 kg ha(-1). The yield of RND, RSN, RSD, and RBN increased by 15.51, 3.06, 10.23, and 1.59%, respectively, while RBD decreased by 5.01% relative to RNN. Direct straw return and straw biochar return coupled with rice-duck co-culture has both negative and positive effects on lodging resistance because of its properties. The stem's mechanical properties were mainly decided by weight, length, plumpness, and culm anatomy. The increased bending moment at breaking, lodging strength, and bending strength with the RND, RSN, RSD, RBN, and RBD treatments increased, indicated an increase in lodging resistance. Our results clearly demonstrate that direct straw return and straw biochar return coupled with rice-duck co-culture could increase the lodging resistance. In total, rice-duck co-culture could increase the lodging resistance with a higher yield. Compared to straw biochar application, straw return can stabilize the yield and improve the lodging resistance of rice. Thus, direct straw return coupled with rice-duck co-culture should be explored for improving lodging resistance under the condition of ensuring yield.

changes in urban construction land;carbon emissions;land transaction data;urban construction
摘要：
Urban construction land has an increasing impact on ecological carbon storage capacity and carbon emissions. Based on the theoretical analysis framework and the panel data of 278 prefecture-level cities in China from 2000 to 2019, this paper analyzes the impact of changes in urban construction land on carbon dioxide emissions. Our results suggest that the increase in urban construction land significantly promotes carbon dioxide emissions, and this conclusion still holds after selecting geographic and historical data as instrumental variables and conducting a series of robustness tests. Importantly, the newly added construction land and industrial land are important sources of increased carbon dioxide emissions, and there exist heterogenous impacts of the urban construction land on carbon emissions across different geographical distributions and different urban sizes. In addition, the results of the quantile regression show that, as the quantile level increases, the impact of changes in urban construction land on urban carbon emissions shows an inverted U-shaped trend that first increases and then decreases. Thus, our results provide evidence for promoting the coordinated development of land transaction marketization and low-carbon urban construction.

Children from low-income families;Multiple risk factors;Psychological adaptation;Latent class analysis
摘要：
Based on the ecological systems theory, this study examined the multiple risk factors experienced by children from low-income families in China and their subsequent impact on children's psychological adaptation. A cumulative ecological risk questionnaire was constructed to examine the exploratory and descriptive risk factors most commonly exposed to children in families, schools and communities. The study sample consisted of 428 children from low-income families (N = 428; M-age = 12.35, SD = 2.51) from 20 ordinary primary and secondary schools across China. We conducted an exploratory latent class analysis using the responses from the cumulative ecological risk questionnaire. The results showed that a three-group solution fit the data best, with the following breakdown: "low-risk" = 41.1%, "family-risk" = 21.7%, and "school-risk" = 37.2%. The three groups showed significant differences in terms of psychological adaptation. The "low-risk" group exhibited fewer problem behaviors and higher prosocial behavior than the other groups. The "family-risk" group showed more significant adaptation difficulties, while the "school-risk" group showed lower levels of prosocial behavior. The results suggest that the ecological risks experienced by children from low-income families had significant group heterogeneity, which may further affect their psychological adaptation.
摘要：
The controversial debate regarding the association between natural resources and sustainability fuels the literature strand to assess their true connection. In this sense, this study revisited natural resources and sustainable development in the case of China from 1982 to 2020. Besides, this study examined the role of remittances, fossil fuel consumption, and technological innovation in sustainable development. Using novel time series specifications, this study validates the stationarity and the existence of a long-run equilibrium relationship between these variables. The irregular distribution of the data forces this study to use the novel method of moment quantile regression - an effective approach that tackles the non-normality issue of data. The empirical results illustrate that natural resources adversely affect sustainable development in the country, which is evident in the resource curse paradox in China. On the other hand, fossil fuel consumption and technological innovation are significant factors of the country's sustainable development. Unlike these variables, remittances have an adverse yet insignificant role in the country's sustainable development. These estimates are found robust as validated by another non-parametric (Bootstrap quantile regression) approach. Based on the empirical findings, this study suggests the sustainable use of natural resources exploitation, productive utilization of remittances, and improve investment in the technological innovation via promoting research and development in the country.

摘要：
Small and fragmented arable land is a key challenge for small-scale agricultural countries, resulting in low labor productivity, ecological damage, and inefficient land use. To cope with this challenge, the farmland transfer (FLT) policy is implemented to establish modern agriculture based on specialization and scale enlargement. Despite the rising body of literature, an overview of the effect of this policy is lacked. This paper aimed to examine the multi-dimensional effects of FLT in China. A systematic search of the Web of Science and Scopus databases revealed 26 full-text peer-reviewed articles. We found that FLT had both positive and negative effects, and its effects were mainly mediated by intermediary factors. Non-contingent FLT and post-FLT actions were responsible for the adverse effects of FLT. In the literature, the influence of FLT on the environment is the most concerning issue. The results also show that the existing evidence on the effect of FLT is insufficient; therefore, this paper proposes to further exploration of the multi-dimensional effects of FLT, institutional feedback, and trade-offs. While FLT offers the potential to address socio-economic and environmental challenges, this study suggests that an institutional framework that takes into account spatial and temporal aspects, land-use, market systems, and household conditions is needed to promote favorable development, and mitigate potential land market problems and ensure sustainable development. Despite significant limitations remain, the literature on the socio-economic and environmental effects of FLT is increasing.
