Coupling Relationship on Eco-economic System of Agricultural Land in Zhifanggou Watershed
摘要
Abstract
The coupling trends of agriculture land eco-economic system can be characterized by the chain structure between agriculture land resources and agriculture industry. This study on coupling relations and coupling trends of agriculture land eeo-economic system was carried out by coupling relational grade and coupling degree based on farm household scale. The results showed:(1) The agricultural land eco-economic system coupling was manifested as resources-restricted industry and industry-stressed resources. Plot, forage utilization, chemical fertilizers, density, Perland, duty of water were principal factor which restricted agriculture industry development. Income effect was principal factor which influence arrangement and exploitation of agriculture land resources. (2) Based on sampling survey, system coupling degree lies between 0.5~0.8 shows that the system coupling development was in running-in coupling. (3) Geographical conditions and agriculture land resources were important reasons for agriculture industry, as well as limited it. Public policy also offered advance guide and condition.关键词
