Agricultural Management in the Agro-pastoral Areas and Functions of Grassland Ecological Protection Subsidy Award System

Quantitative assessment of ecological vulnerability is of great significance for ecological protection and restoration in ecologically vulnerable regions. Here, the ecological vulnerability of the northern sand prevention belt (NSPB) of China was assessed using an ecological pressure–sensibility–resilience model from 2000 to 2015. Results showed that the ecological vulnerability index (EVI) displayed low values in the eastern part and high values in the western part of the study region. The EVI ranged from 0.29 to 1.32 in 2000, with the mean value of 0.88, whereas it averaged 0.78 in 2015, ranging from 0.21 to 1.26. Decreasing EVI from 2000 to 2015 indicated that the ecological status has been improved. Moreover, the area proportion of moderately, heavily, and extremely ecological vulnerability levels occupied approximately 87% in both 2000 and 2015, indicating a high ecological vulnerability level. Furthermore, the change in area proportion of different ecological vulnerability levels were associated with the change in the spatial distribution of vegetation coverage, indicating that eco-environmental protection projects were indeed effective. These findings indicated that differential strategies in different restoration zones should be adopted, especially in the western parts of the study region, and eco-environmental protection projects should be reinforced to improve the ecological restoration.

Identifying geographical spatial conflicts and optimizing development patterns are important prerequisites for eliminating the conflicts of geographical spatial conflict. The paper takes the Wuhan Metropolitan Area as an example. Using grid-scale data, we construct a multi-functional suitability evaluation index system for geographical space, starting from three dimensions: ecological protection, agricultural production and urban construction. The multi-index comprehensive evaluation method is used to measure the geographical spatial suitability level and identify the characteristics of geographical spatial conflict patterns. Three-dimensional Rubik's cube model is used to divide the space conflict types and optimize the partition. We found that the areas with suitable ecological protection functions and more suitable areas are mainly distributed near the waters and the Dabie Mountains and Mufu Mountains with relatively high altitude in Wuhan Metropolitan Area. Suitable areas for agricultural production functions are concentrated in the Jianghan Plain. Suitable areas for urban construction functions are concentrated around urban areas, established towns, and major transportation routes. Regions with high intensity of land and space conflicts are mainly located in the central and northwestern parts of the Wuhan Metropolitan Area. Regions with low levels of conflict are concentrated in the west, northeast, and southeast regions of the Wuhan Metropolitan Area. The degree of geographical spatial conflict in Wuhan Metropolitan Area can be divided into three primary zones and 12 secondary zones, which are intense conflict zone, general conflict zone, and weak conflict zone. Based on multi-functional perspective, identifying and analyzing the types of geographical spatial conflict will help locate the development direction of different conflict areas and provide theoretical and technical support for the optimization of geographical space.

Environmental Expenditures

This article studies how the allocation structure of bank credit capital between state-owned and private enterprises and government environmental expenditures affect environmental pollution in China. The present literature argues that credit allocation and government environmental expenditures may play an important role in environmental quality improvement. However, these studies rarely consider the credit allocation structure between State-owned enterprises (SOEs) and private enterprises; in addition, they overlook the interaction effects of credit allocation and government environmental expenditures. Based on these, we put forward three hypotheses. Moreover, the study applies relevant spatial data for 2011–2017 from 31 provinces in China to a spatial econometric model, and the results indicate that (1) environmental pollution among provincial regions shows a significant positive spatial autocorrelation. (2) Environmental expenditures and environmental pollution display an inverse U-shaped relationship, which supports the numerical simulation results. (3) The interaction effect of credit allocation structure and environmental expenditures on environmental pollution is significantly positive, which means that the allocation of more credit capital to private enterprises will restrain the effect of government environmental expenditures. With the increasing significance of environmental protection in China, it is necessary to strengthen the supervision of private enterprises’ environmental pollution behavior, expand government expenditures on ecological protection, and promote regional collaborative environmental governance to improve environmental quality.
