摘要

对农业发展现状的识别和判定，是实现农业可持续发展的前提和基础。根据岩溶山区特点，以重庆市14个典型岩溶区县为评价对象，探索了适合岩溶山区的农业可持续发展评价体系，并借助因子分析方法建立了计量模型，初步确定了各区县的农业可持续发展程度。研究对比发现，各区县农业可持续发展程度差异较大，是地区经济总体发展水平、人口压力与土地资源丰度、生态环境基数、石漠化现状等共同作用的结果。为推进重庆各岩溶地区农业的可持续发展，建议改变不合理的土地利用方式，实行农业多样化和产业化经营，促进资源的有效利用，减少农业污染，合理规划并确立适宜的农业可持续发展模式。

Abstract

The recognition of present agricultural status is helpful to realize the sustainable development of agriculture.The appropriate assessment system of agricultural sustainable development of 14 karst counties in Chongqing Municipality is studied based on the characteristics of the karst eco-environment.By factor analysis method

a mathematic model evaluating the quantitative level of agricultural sustainable development is established.Regional economic level

population stress

abundance of land resources

agricultural produetion pattern

and karst rocky desertification are found to be the key factors.Agricultural structure should be adjusted

pattern of agricultural industries should be optimized

soil and water pollution should be controlled

and scientific agricultural development plans should be set down.
