我国循环农业发展时空差异及制约因素分析

为了便于比较我国循环农业发展的历史轨迹和区域差异,构建了一套统一的评价指标体系,并从时间和空间维度上对我国循环农业发展进行了综合评价和制约性分析。结果显示：1999-2008年间我国循环农业发展水平总体呈现出上升态势。从因素类型来看,经济与社会发展对我国循环农业发展的制约性先增强后减弱,资源的减量投入制约最大且逐年增强,资源循环利用和资源环境安全的制约性逐年减弱;2008年我国31个省市区的循环农业发展差异明显,水平较高的地区主要集中在东北和中西部地区,而水平较低的则主要集中在东部沿海地区。

Analysis on Spatial and Temporal Differences and Constraints of Circular Agriculture Development in China

In order to compare the historical track and regional differences of China＇s circular agricultural development,this paper established a set of unified evaluation system and made comprehensive evaluation and constraining analysis on circular agriculture in China.The result indicated that generally China＇s circular agriculture was showing the rising trend from 1999 to 2008.As for the factor types,the constraints of economic and social development on China＇s circular agriculture first increased and then decreased,the input constraints of resources reduction is the largest and increases year by year,while the constraint of resources recycling and resources environmental safety is gradually weakening.In 2008,the development of circular agriculture in China＇s 31 provinces,municipalities and autonomous regions had showed the significant differences,with the higher level of development in the northeast and midwest part and the lower level in the eastern part of China.These conclusions will provide important information for the making of relative policy in circular agricultural development.
