基于能值分析的宁夏农业生态经济系统可持续发展研究
Research on sustainable development of agricultural ecological economic system based on emergy analysis in Ningxia
摘要
Abstract
Emergy analysis method provides a unified approach for the comparison and analysis of input and output of the agricultural ecological economic system, and its index system provides a quantitative method for calculating sustainable development of the agricultural ecological economic system as well. This paper calculated the emergy input of environment and resources and auxiliary energy, the emergy output, the emergy self-sufficiency ratio, the emergy investment ratio, the emergy yield ratio, the environmental loading ratio, and the emergy sustainability index of Ningxia agricultural ecological economic system. The analysis results show that the emergy input of environment and resources is too much, and Ningxia agricultural ecological economic system has high emergy self-sufficiency ratio, low emergy investment ratio, low emergy yield ratio and low environmental loading ratio which show that Ningxia’s agricultural development is still in the traditional agriculture model and it’s sustainable development index is in appropriate level.关键词
