重庆市循环农业的区域测度分析

以重庆市39个区县为对象,采用系统分析方法,构建表征循环农业特征的三级指标体系。根据重庆市"一圈两翼"发展区域,对比研究各区县循环农业的发展度、协调度和障碍度。结果表明,重庆市循环农业的发展度和协调度基本上体现了农业生产低投入和资源循环利用低水平的特征;而障碍度表明对循环农业发展制约程度最高的二级指标为资源循环利用,最弱的为农业生产投入。因此,重庆市发展循环农业时,应增加水患意识,发展节水农业,同时发展以沼气为纽带的生态家园富民工程,提高作物秸秆综合利用率。重庆市循环农业按经济地理分类,一小时经济圈属于良好型,东北翼、东南翼分别属于中等型和一般型。按照发展度、协调度和障碍度等指标,将39个区县的循环农业特征分为良好、中等、一般和欠缺等4种类型。

Regional measure of recycle agriculture in Chongqing City

A 3-level index system characterizing recycle agriculture in Chongqing City was constructed using systematic analytical method.Based on development strategy of One-Hour Economic Circle(OHEC) and Two-Wing of Chongqing City,the degree of development,coordination and constraints on recycle agriculture in 39 districts/counties in Chongqing City were analyzed.The results for development degree and coordination degree show that recycle agriculture in Chongqing City basically represents low input in agricultural production and limitations in circulatory utilization of resources.While the constraint degree indicates circulatory utilization of resources as the most important obstacle to recycle agriculture in Chongqing City.The least obstacle is agricultural production input.Water shortage awareness,development of water-saving agriculture and ecological engineering,and augmented and comprehensive utilization of crop stalk are the prerequisites for the full realization of recycle agriculture in Chongqing City.Based on the economy and geography,the recycle agriculture in OHEC,Northeast-Wing and Southeast-Wing of Chongqing City are appraised as good,medium and common respectively.A comprehensive analysis of the degree of development,coordination and constraint shows that recycle agriculture in the 39 districts/counties of Chongqing City can be classified into four as: good,medium,common and poor.
