基于能值的农业生态经济系统动态分析——以河北省武安市为例
The Dynamic Analysis of Agro-ecological Economic System on the Basis of Emergy
摘要
Abstract
Using the method of emergy analysis,we analyze the input and output of agro-ecological economic system,and select five indicators (net emergy yield ratio,emergy investment ratio,environmental loading ratio,emergy sustainability index,and dominance of emergy yield system) for assessment. The results show that the emergy input-output in Wu' an City is in general on the rise; the emergy investment ratio rises constantly, but the net emergy yield ratio decreases, and the comparative advantage in the prices of agricultural products is gradually lost. At the same time, with increase in the non-renewable industrial support emergy, the environmental pressures are also mounting. In the future agricultural development,it is necessary to pay more attention to the coordination between agricultural development and ecological environment, achieving sustainable development of agriculture.关键词
