湘中丘陵盆地区农业生态环境脆弱性评价——以衡阳盆地为例
Assessment on the Vulnerability of Agricultural Eco-environment of Hilly Basin Area in the Middle of Hunan Province
摘要
Abstract
[ Objective] The study aimed to assess the vulnerability of agricultural eco-environment of hilly basin area in the middle of Hunan Province. [ Method] Taking Hengyang basin as an example, we firstly chose 13 indicators from natural, social and economic subsystem to assess the vulnerability of agricultural eco-environment in Hengyang basin of Hunan Province. Afterwards, by using principal component analysis , we calculated the weight of each indicator and the vulnerability of agricultural eco-environment of seven regions, finally analyzed the spatial distribution of agricultural eco-environment vulnerability. [ Result] The weight of farmers' net income per capita was up to 0. 140, followed by forest coverage rate (0. 137). Among the seven counties, the vulnerability of agricultural eco-environment was primarily moderate, while Hengnan County had the highest vulnerability among the seven counties, followed by Hengyang County, and the two counties were referred as seriously fragile regions. In addition, Leiyang City was the minimum fragile region, namely slightly fragile region. In general, the vulnerability of peripheral counties was lower than that of central counties. [Conclusion] The research could provide scientific references for the restoration and reconstruction of agro-ecological environment as well as the establishment of agricultural production decisions.关键词
