摘要：
In order to solve the problem of resource ecological compensation, this paper proposed a model of resource ecological compensation mechanism based on a rural leisure sports environment. The model is carried out in many places in China. The survey data involves 31 provinces, 10 years, and 43 indicators, with a total of 43 x 10 x 31 = 13,330 data. The preliminary basis of mechanism construction is summarized from four aspects. Finally, make full use of modern information technology to improve the network platform of the compensation mechanism, promote the efficient allocation and comprehensive utilization of ecotourism resources, and lay a solid foundation for establishing a reasonable and perfect resource ecological compensation mechanism and ensuring the long-term and stable operation of the mechanism. Through the experiment, it is found that the timely and effective publication of information can eliminate the inner estrangement between the two sides, so as to make the behavior of both sides more rational. A special information feedback department is established to deal with the opinions put forward by all compensation parties in tourism development, extract effective information, summarize and publish reasonable guidance information, and guide the compensation of both sides to an ideal balance through the feedback of this information. The effectiveness of the experiment is verified.

摘要：
Uranium and arsenic are two pollutants commonly found in groundwater near uranium mines. However, the reactivity of U(VI) and As(V) need to be carefully investigated to better understand their fate and transport in the environment. In this study, the reactivity of U(VI) and As(V) were studied under various pH, bicarbonate, and Ca2+ levels. In air-equilibrated systems, the reactivity of U(VI) and As(V) generally decreased with the increase in pH, as evidenced by the solubility of U(VI) and As(V) increasing along with the elevation of pH. At pH = 8, 44.70% and 37.81% of initially added U(VI) and As(V) remained soluble. The addition of 1 mM of bicarbonate increased the reactivity of U(VI) and As(V) at mild acidic to neutral pH; however, the presence of bicarbonate significantly increased the solubility of U(VI) at mild alkaline condition, as nearly all U(VI) remained soluble at pH values of 8 and 9. After the addition of Ca2+, the solubility of both U(VI) and As(V) decreased at mild acidic to neutral pH ranges; however, the addition of Ca2+ markedly increased the soluble percentages of U(VI) at neutral pH, in which the condition 97.81 +/- 2.95% of U(VI) remained soluble. Comparatively, only 36.13 +/- 4.98% and 1.69 +/- 1.08% of U(VI) were soluble at the same pH in air-equilibrated and bicarbonate systems. Our study demonstrated that U(VI) and As(V) are less reactive at neutral to alkaline conditions. Furthermore, the addition of bicarbonate and Ca2+ can further reduce the reactivity of U(VI) and As(V) at neutral to alkaline conditions. The findings of this study contribute to a deeper understanding of the fate and transport of U(VI) and As(V) in groundwater and could aid in better designing of U(VI) and As(V) removal processes.

摘要：
This study explores the incidence and trend of zoonoses in China and its relationship with environmental health and proposes suggestions for promoting the long-term sustainable development of human, animal, and environmental systems. The incidence of malaria was selected as the dependent variable, and the consumption of agricultural diesel oil and pesticides and investment in lavatory sanitation improvement in rural areas were selected as independent variables according to the characteristics of nonpoint source pollution and domestic pollution in China’s rural areas. By employing a fixed effects regression model, the results indicated that the use of pesticides was negatively associated with the incidence of malaria, continuous investment in rural toilet improvement, and an increase in economic income can play a positive role in the prevention and control of malaria incidence. Guided by the theory of One Health, this study verifies human, animal, and environmental health as a combination of mutual restriction and influence, discusses the complex causal relationship among the three, and provides evidence for sustainable development and integrated governance.

摘要：
Provincial PM2.5 pollution management in China is facing great challenges, which is necessary to formulate hierarchical management strategies according to the specific situation of each province to achieve environmental equity management. This work calculates and analyzes the baseline value of PM2.5 in 31 provinces in China from 2018 to 2019 using the cumulative frequency curve method. Results showed that 93% of the provinces have two inflection points in the cumulative frequency curve, indicating that human activities showed a significant impact on PM2.5. The obtained baselines were assuredly lower than the corresponding monitoring values, which represented upper limits of PM2.5 in a certain area under low human activities. According to the relative size of baseline values, monitoring values, and national standard values, the following three types of results were obtained. Category I was classified as the standard value > monitoring values > baseline value. Category II was classified as the monitoring values > baseline value > standard value. Category III is the monitoring values > standard value > baseline value. A more practical hierarchical management strategy is formulated according to the relationship between baseline, monitoring, and standard values. Category I keeps the current status while striving to bring PM2.5 emissions closer to the baseline value. Category II implements the ‘step-by-step’ measures of reducing to the baseline value and then to the standard val...

摘要：
Grafting is commonly used to enhance the quality and confer biotic or abiotic stress tolerance to plants. There is, however, no clear understanding of how grafted eggplant responds to cold stress. Here, four grafting combinations of eggplant from cold-sensitive line J55 and cold-resistant line J65 were subjected to morpho-physiological experiments and transcriptome sequencing to compare their responses to cold stress. After being subjected to cold stress, a total of 5883,6608,6867 and 5815 differentially expressed genes (DEGs) were identified in J55-J55L0_vs_J55-J55L1 (C0), J55-J65_vs_J55-J65L1 (T2), J65-J55_vs_J65-J55L1 (T1), and J65-J65_vs_J65-J65L1 (C1), respectively. When comparing C0 and C1, there exist 4580 specifical DEGs which were differentially expressed either in C0 or C1 (C0_vs_C1), these DEGs are more likely to induce the difference of the two grafted combinations. There is a total of 5583 specifical DEGs in C0_vs_T1 and 5209 specifical DEGs in C0_vs_T2, respectively. GO functional analysis found specifical DEGs mainly enriched the cell and membrane, catalytic activity, metabolic process, and cellular process, which was the same in comparison to heterografted and self-grafted eggplant in C0_vs_C1, C0_vs_T1 and C0_vs_T2. KEGG analysis showed that the specifical DEGs were mainly enriched in plant hormone signal transduction in C0_vs_C1, C0_vs_T1, and C0_vs_T2. Therefore, we screened ten candidate genes associated with AUX/IAA, salicylic acid and other hormone regulations that were differentially expressed in C0_vs_C1 C0_vs_T1, and C0_vs_T2. We believe that plant hormones play a vital role in regulating the cold tolerance of grafted eggplant. We also found that 22 DEGs enriched in arginine and proline metabolism in comparison to self-and hetero-grafted eggplant C0 and T1, predicted that putrescine biosynthesis plays a certain role in improving the cold resistance of eggplant by heterologous grafting. Meanwhile, by the comparison of specifical DEGs on C0_vs_C1 and C0_vs_T2, the DEGs enriched in a similar KEGG pathway, it is considered that the better cold tolerance of J65 as a scion has a more important effect on the cold resistance of eggplant.

摘要：
In order to solve the effects of environmental factors on the droplet settlement of a nutrient solution on plant roots when planting plants with ultrasonic aeroponic cultivation, this study aimed to obtain a suitable wind speed range and atomization time through a nutrient solution atomization experiment, to obtain the best control scheme through a multi-environmental parameter combination cultivation experiment. Taking an ultrasonic aeroponic cultivation device as the research object, and lettuce as the test material, experiments were carried out on two factors affecting the wind speed of an axial fan and the atomization time of the nutrient amount of ultrasonic aeroponic cultivation plants; the suitable wind speed range was 1.0-2.5 m/s. The temperatures of the lettuce root zones in the upper, middle, and lower layers of the ultrasonic aeroponic cultivation device at different time periods were obtained by atomizing the nutrient solution. When the optimum temperature for the root growth of lettuce was 15-20 degrees C and the wind speed was 1.0-2.5 m/s, the continuous atomization time of the nutrient solution was 66-184 min. Using a quadratic orthogonal rotation combination design method, three main factors, namely wind speed, ambient temperature, and atomization time, were selected to test droplet settlement in the lettuce roots. The droplet settlement in the lettuce root system was measured. The droplet settlement regression equation in the lettuce root system was established. The reliability of the regression model was tested according to the significance condition, and a simplified quadratic orthogonal regression equation was obtained. The main effect analysis, single factor analysis, and interaction effect analysis were used to analyze the model, and the model was further verified. The verification results showed that the relative error between the predicted value and the actual value of the average root droplet sedimentation was 5.8%. The optimum wind speed was 2.5 m/s, the ambient temperature was 16 degrees C, and the atomization time was 184 min when the ultrasonic aeroponic cultivation device designed in this study was used to cultivate lettuce. It could provide a theoretical reference and an experimental basis for the control of the related growth environment parameters of plants cultivated using ultrasonic aeroponic cultivation.

摘要：
Background: Together with the rapid development of China’s economy, the number of urban residents suffering from depression and psychological disorders has been increasing as a result of the general increase in life stress. As a consequence, this study investigates the effects on users’ mental health through exercise and social interaction in three different outdoor natural landscapes, and provides theoretical and practical guidance for urban landscape planning and design. Methods: In this study, pre- and post-DASS21 (depression, anxiety and stress) data were obtained by using the DASS21 scale (used to assess depression, anxiety, and stress) to test a population of users performing simple exercise and social interactions in three natural environments, and the data scale values were statistically analyzed using SPSS. Results: (1) In the natural outdoor environment within the community, there was a relationship between the outdoor environment and perceived atmospheric temperature, with (single) and (group) perceived outdoor temperatures in the community having smaller effects on the mood of community residents; (2) After analyzing the data by descriptive statistics (p < 0.05), it was found that there was a slight change in the mean scores both before the participants climbed Yuelu Mountain and after they reached the summit; the mean scores of stress, anxiety, and depression decreased after they reached the summit, and the condition improved; (3) There was a slight change in the mean of both scores before the departure to and after the return from the Tongguan Kiln attractions, with a slight improvement in the condition after the return of the stress and depression mean scores. Conclusions: Enhancing social relationships through exercise and social interaction in a natural environment in different populations significantly increases the benefits for mental health (depression, anxiety, and stress) and assists recovery from stress-related mental disorders. Different landscape types and landscape attribute characteristics have different effects on urban residents’ preferences and mental health. Rich natural landscapes, providing green exercise environments, and t social interactions have positive effects on the mental health of urban residents. Especially in environments where the change in altitude is around 200 m, climbing is very beneficial to psychological emotions.

Abstract: Rice is the staple food for 2.5 billion people worldwide and most farmers depend solely on rice for their livelihood. This study estimates how paddy ecosystem elasticity and external human activity affect paddy ecosystem sustainable food supply. In particular, we analyzed how sustainable food supply is affected by three key domains of external factors—ecological factors, including the proportion of paddy Area (Are), per capita cultivated land area (Lan), and annual wastewater discharge per capita (Was); economic factors, including the agricultural economy level (Inv) and urbanization rate (Urb); and social factors, including the education of farmers (Edu) and rural medical level (Med). We use ANEV, or net paddy ecosystem services value per unit area, to assess the sustainable food supply, which not only represents the food supply quantity and quality, but also the sustainability of the food supply. Results from our panel and threshold regressions suggest that Lan and Urb have a threshold effect on paddy ANEV; Are, Was, Inv, and Edu have a linear negative correlation with ANEV; and Med has a positive linear correlation with ANEV. Based on our findings, we lay out a series of recommendations that may guide future formulation of policies on paddy ecosystem protection and sustainable food supply. Keywords: sustainable food supply; policy; paddy ecosystem elasticity; threshold effect; ANEV
