贵州省农业生态安全性评价

Evaluation of agroecological safety in Guizhou Province

为了对贵州省农业生态安全的区域分布现状进行研究,加强和重视农业生态安全的定量评价,给贵州省农业自然灾害风险管理提供定量参考,根据贵州省农业生态的特点,设计了贵州省农业生态安全评价指标体系。运用主观评价与客观评价相互综合的评价分析方法,对贵州省各县(市)的农业生态安全状况进行了综合评价。将贵州省农业生态安全划分为四个等级,相对低安全区主要分布在贵州西部高海拔地区,相对较安全区主要分布在贵州东部部分区域。得到了贵州省农业生态安全区划图,并分析了影响贵州农业生态安全的主要原因。

In order to study the regional distribution, strengthen the quantitative evaluation of agricultural ecological safety in Guizhou Province and provide quantitative reference to risk management of Guizhou agricultural natural safety was disaster, an evaluation system of agricultural ecological safety was designed according to agro-ecological characteristic in Guizhou Province. Agricultural ecological safety situations of various counties and cities in Guizhou Province were comprehensively evaluated by the approach of synthesizing subjective and objective evaluation. The agricultural ecological safety of Guizhou Province was classified as four grades; relatively low safe areas distribute mainly in the west of Guizhou, where altitude is high, and relatively safe zones distribute mainly in the east. A regionalization map of agricultural ecological safety was made, and the main reasons of affecting the agricultural ecological safety were analyzed.
