吉林省中部粮食主产区循环农业发展评价分析

Evaluation of Circular Agriculture Development of the Major Grain Producing Areas of Central Jilin Province

在分析循环农业内涵、原则和技术目标的基础上,从经济社会产出、外部性物质减量投入、农业资源循环利用、农业环境安全4个方面建立循环农业评价指标体系。运用熵权系数法对2010年吉林省中部粮食主产区15个县的循环农业发展水平进行综合分析评价,按照评价指数将15个县域的循环农业发展水平划分为4个等级。通过障碍度计算,诊断分析了2010年吉林省粮食主产区的各个县域的循环农业发展的制约性障碍因素,并提出了循环农业发展的优化调控建议。

Based on the principle, intension, technical objectives of circular agriculture, the paper established index system of circular agriculture development from economic and social development, resource reductions inputs, recycling re- sources, resources and environmental safety aspects. The paper used the entropy method to evaluate comprehensive 15 counties of the major grain producing areas of central Jilin Province in 2010, according to the hierarchical cluster analysis; level of circular agriculture about 15 counties could be distributed into four grades. Through the calculation of the obstacle amounts, the paper diagnostic analyses the obstacle factor of agricultural development of each county in the major grain producing areas of central Jilin Province in 2010. Finally, the paper put forwards the corresponding suggestions on development of circular agriculture.
