黄淮海地区农业生态经济系统能值分析
Emergy Analysis of Agroecosystem in Huang-huai-hai Region
摘要
Abstract
In this paper,the emergy input and output,environmental loading and running effect of agroecosystem in Huang-huai-hai region were quantitatively analyzed to better evaluate its operating characteristics and the sustainable development ofagrienlture based on the theory of emergy analysis by structuring index system for agroecosystem cmergy estimation. The results show that the agroecosystem in Huang-huai-hai region has higher efficiency of emergy output, better effect of running, stronger manet competition, more powerful environmental carrying capacity and sustainable development capacity, but it still at the stage of petroleum agriculture, chemical fertilizer, pesticide and plastic film etc. Unrenewable industrial emergy raising by big percentages leads to its sustainability of decreasing trend to a certain degree, and causes greater pressure to the ecological environment which we should pay more attention to. To promote the sustainable development of agriculture in Huang-huai-hai region, we should gradually adjust the invesunent proportion of input and output emergy; strengthen the research and extension of agricultural science and technology; properly decrease non-renewable industrial assistance emergy represented by fertilizer investment; change the model of chemical agricultural production; taken the road of sustainable agricultural development关键词
