东部地区农业污染已成为我国最为严重的环境问题之一,该研究对于推进与环境相协调的区域可持续发展实践、“建设美丽乡村”具有战略指导意义。首先建构了农业环境-经济系统耦合模型及耦合度评价类型;然后基于环境压力水平、强度等方面农业污染风险评价指标,以及农业经济水平、强度等方面农业经济系统评价指标,运用因子分析法实证研究东部地区农业环境-经济系统耦合及其空间格局。东部地区农业环境-经济耦合空间发展不平衡,大致可划分为5大类型区,农业污染风险高且环境-经济耦合度较差的地区主要在冀北、冀南地区,鲁西北、鲁南地区,苏北地区、闽南地区及粤西地区等,这可为具有地域特色的农业环境-经济协调发展提供决策依据。
The agricultural pollution in the eastern region has become one of the most serious environmental problems in our country. The study is of strategic importance in promoting sustainable development in the region in harmony with the environment and in building a beautiful country. Firstly, the agricultural environment-economy system coupling model and the coupling evaluation type were constructed. Then, based on the evaluation index of agricultural pollution risk in terms of environmental pressure level and intensity, and agricultural economic system evaluation index of agricultural economy, To study the coupling of agricultural environment-economy system and its spatial pattern in eastern China. The unbalanced development of agricultural environment-economy coupling space in eastern China can be roughly divided into five major types of regions. Areas with high agricultural pollution risks and poor environmental-economic coupling are mainly located in northern Hebei, southern Hebei, northwestern Shandong, southern Shandong , Northern Jiangsu, southern Fujian and western Guangdong, which can provide the basis for decision-making on the agricultural environment-economy coordinated development with regional characteristics.
