摘要：
I was invited to make a brief commentary on a recent article titled “Determining Spatially Varying Profit-Maximizing Management Practices for Miscanthus and Switchgrass Production in the Rainfed United States” published in GCBB by Zhang et al. (2022). In the work, they propose management practices to maximize profitability through economically optimal N fertilizer application, temporal and spatial variation, and optimal age rotation of two energy crops. This interesting and thoroughly investigated result would be instructive for the applications of perennial energy crops.

摘要：
Adopt building design and home interior design into the design processes so that both sides would be improved as required for the trend of social development. Therefore, this article would make deep analysis towards building and home design at this big data era based on concepts of building and home design integration. The analysis covered 4 aspects, building and home interior structure integration, cultivation integration, management and implementation integration, user engagement integration, which formed the integrated mode of building and interior home design, aiming to provide a brand new view of practical design plan towards building and home interior, and brings valuable reference for designers.

摘要：
The principles of circular economy development are "Reduce, Reuse and Recycle", designed to help ensure productivity, as well as access to long-term benefits which has become the community's focus with its importance recognized. The performance of circular economy refers to the results achieved by region, park or enterprise after taking certain measures of circular economy. The Agricultural Industrial Park is a new agricultural development model. The circular economy of the Agricultural Industrial Park advocates the progressive circular economy development model based on the ecological agriculture construction. It is the feedback process of "resources - agricultural products - renewable resources". In view of the current situation of circular economy development in agricultural industrial parks, this paper takes the agricultural industrial parks in Hunan Province as an example and conducts empirical investigations and analyses on the basis of the circular economy theory. It constructs the circular economy performance evaluation indicator system combining the characteristics of the Agricultural Industrial Park, and evaluates the circular economy performance through analytic hierarchy process and fuzzy comprehensive evaluation method. The results show that circular economy has achieved initial success in agricultural industrial parks, but it needs improvement and optimization.

摘要：
Large-scale pig farm is a intensive and standardized breeding model. Co mpared with general pig farm, large-scale pig farm can better solve environmental pollution problems, reduce resource losses, and achieve win-win situation of economic and environmental benefits. Material flow cost accounting (MFCA) is one of the most representative environmental cost management tools. Different from the traditional cost accounting, the main function of material flow cost accounting is the visualizat ion of resource loss. In view of the current situation of large-scale pig farm, this paper takes a large-scale pig farm in Hunan Province as an e xamp le and analyses the whole cost of large-scale pig farm based on the principle of material flow cost accounting. It constructs the material flo w cost model co mbining the characteristics of the large-scale pig farm. The results show that there are lots of hidden costs during the pig production and biogas engineering process. Therefore, this paper aims to determine the loss of resources fro m the perspective of material flo w cost accounting to propose the optimization suggestions of circular economy for large-scale pig farms.
摘要：
To facilitate more convenient travel as the economy of Macau expands, the government of Macau has allowed casinos to add free shuttle buses (FSB) and drivers. In this paper, we optimise the operation cost of FSB based on the number of FSB and FSB's driver population in Macau. Firstly, we investigate the operational conditions of the FSB in each depot, including the transit time of FSB and the number of passengers. Then, we propose a series of integer programming models to optimise the population of FSB and FSB drivers. Finally, through a practical demonstration using Excel to solve the linear programming (LP) model, this paper concludes that the numbers of FSB and drivers have a reduction of 43.68% and 33.6%, respectively. It implies that the operation cost of FSB could be reduced by 270,900,000 HKD in purchasing of FSB and 38,678,400 HKD/year in employing drivers of FSB.

摘要：
Biomass is one of the renewable energy sources on which policy makers are greatly dependent on since it is a flexible feedstock capable of conversion into electricity, transport liquid fuels and heat by chemical and biological processes on demand. Though numerous publications have examined the relationship of economic growth with renewable energy and other parameters, biomass energy has never been included in these studies. Then, this study examines the causal relationship within a multivariate panel cointegration/error correction framework which combines the cross-section and time series data while allowing for heterogeneity across different provinces. After employing panel data regression model ranging from 2003 through 2012 to examine the relationships of biofuels production with sustainable development in China, the paper concludes that the development of biofuel energy production integrated with the consideration of the improvement of income per capita, and the attraction of more capital investment, does make a significant contribution to economic growth. However, some negative side effects including the increase of greenhouse emissions and the decrease of marginal land still coexist with the economic development. Of course, the importance of these findings lies on their implications and their adoption on strategic policies.

This paper estimates carbon emissions from agricultural production in China's Hunan Province during the period from 1998 to 2012. It also analyzes trends in the development of agricultural carbon emissions and the decoupling relationship between carbon emissions and the agricultural output of Hunan. In this study, emissions from two key segments of the agricultural sector were quantified: (1) crop production and (2) livestock and poultry production (singular). A combined method of principal component analysis (PCA), multiple regression analysis, and decoupling analysis was employed to assess the drivers of agricultural carbon emissions. This showed that there was a weak and unstable decoupling relationship between agricultural carbon emissions and their output value during the period of study. The PCA revealed that two main factors-urbanization rate and nitrogen fertilization per acre-explained 92.51 % of the variation in the 11 factors that affected carbon emissions from crops. Also, two main factors (i.e., agriculture per capita GDP and the ratio of beef production to total livestock production) explained 86.27 % of the variation in nine factors that affected carbon emissions from the livestock and poultry industry. Using the PCA scores as independent variables, a multiple regression analysis of carbon emissions from the crop industry and the livestock and poultry industry showed the following patterns. (1) Theoretically, given a 10 % reduction in nitrogen fertilization per acre, crop carbon emissions would decrease by 519 units. If the rate of urbanization were to increase by 1 %, crop carbon emissions would increase by 83 units; (2) similarly, a 1 % reduction in the beef: total livestock and poultry production ratio would reduce carbon emissions from that industry by 329 units, and with "agricultural per capita GDP'' growth of 1 unit, those emissions would increase by 0.354 units. The results of this study contribute to evaluating the sustainability of agricultural production in the region, and they provide a foundation of knowledge for future development of related agricultural mitigation policy and low-carbon agricultural technology.

摘要：
Sustainable development of Resources-oriented Enterprise is one of the most significant problems faced in the process of the reality of Hunan "Four Modernizations and Two models". This article forms the "Basic Reference Frame" of the objective predictions of sustainable development Hunan resource-based enterprises, and constructs four levels of sustainable development index system, including layer of target, criterion, element and specific index. Based on the "Basic Reference Frame" and index system, advance the sustainable development specific target of the resource-based enterprises in 2015 and 2020.
