摘要
在相对可持续发展能力评估的基础上,完成了基于比较优势的中国农业可持续发展区划。首先建立了具有农业资源、农业发展、环境生态、农村社会、科教管理5个支持系统的农业可持续发展总能力指标体系,共选择源指标95个, 采用相对资产/负债评估方法,对省(市、区) 级各支持系统和总能力的相对净资产(比较优势) 进行了评估,并用GIS与图形库联结显示空间分布。然后在此基础上依据区划原则将中国分为9个农业发展地区(一级), 22个农业发展副区(二级), 一级地区反映农业可持续发展和问题治理的方向,二级副区反映农业可持续发展的水平,从而建立起中国农业可持续发展区划系统。
On the basis of relative superiority assessment, this paper achieves regionalization of sustainable agricultural development of China.Firstly, an index system of sustainable agricultural development of China is built, including 5 supporting subsystems of agricultural resources, agricultural development, environment and ecosystem, rural society, and science-education management, and 95 factors at provincial level are selected as basic indicators. Secondly, a relative assets/debt assessing method is used to gain relative net assets values (relative superiority) of every province or municipality directly under the Central Government at the 5 supporting subsystems and the total capability. Then the assessment results are graded and shown as distribution maps by GIS. Thirdly, according to the assessment result of sustainable agricultural developing capability, the whole nation is divided into 9 agricultural developing regions (first level) and 22 sub-regions (second level). The first level reflects each region's direction for sustainable agricultural development and issues' management. The second level reflects whether or not each sub-region reaches sustainable agricultural development and its degree. Thereby regionalization of sustainable agricultural development of China is set up. Based on the above-mentioned assessment and regionalization, this paper puts forward the target of sustainable agricultural development in China: (1) The eastern area of China must enhance its level of sustainable agricultural development, increase its science input, modulate its inner structure; and focus on intensive, commercial and green agriculture. (2) The central and western parts of China must change their situation firstly, and then improve their sustainable developmental level. (3) In western China development, the key policies are focused on ecological construction, producing input, social and scientific management in rural area.
