摘要

[目的]对青海省海东市6个区县的生态脆弱性进行定量研究，为缓解高寒贫困山区贫困状态、提高生态环境保护意识提供参考，为国家深入实施精准扶贫工作提供依据。[方法]选择经济发展状况、社会发展状况和自然生态环境状况3个评价维度构建高寒贫困山区生态脆弱性评价指标体系，运用熵权灰色关联法，对其进行定量分析与评价。[结果]互助县生态脆弱度为0.850 1，属微度脆弱等级，平安区生态脆弱度为0.712 8，属轻度脆弱等级，循化县生态脆弱度为0.557 3，属于中度脆弱等级，乐都、民和及化隆3区县生态脆弱度均小于0.45，属于重度脆弱等级。青海省海东市高寒贫困山区生态脆弱性评价指标的综合关联度从高到低的顺序依次为：互助县 > 平安区 > 循化县 > 化隆县 > 乐都区 > 民和县。[结论]自然生态环境状况和资源禀赋严重制约经济社会发展的同时，对生态脆弱性也有显著的影响。

Abstract

[Objective] The ecological vulnerabilities of six counties and districts in Haidong City

Qinghai Province were quantitatively studied in order to alleviate poverty in high-cold and poverty-stricken mountainous areas

improve awareness of environment protection and provide basis for the implementation of national "precise poverty alleviation" policy.[Methods] The evaluation index system of ecological vulnerability in high-cold and poverty-stricken mountainous area was constructed from three dimensions of economic development

social development and the ecological environment. The index system was quantitatively analyzed and evaluated by the gray correlation method of entropy weight.[Results] The ecological vulnerability in Huzhu County was 0.850 1

which belonged to the slight vulnerability. The ecological vulnerability in Ping'an District was 0.712 8

belonging to light vulnerability level. The ecological vulnerability in Salar Autonomous County of Xunhua was 0.557 3

belonging to moderate vulnerability level. The vulnerabilities of ecological in Ledu

Minhe and Hualong

were less than 0.45

belonging to severe vulnerability level. The vulnerabilities of the six counties and districts in Haidong City were ranked as:Huzhu County > Ping'an District > Salar Autonomous County of Xunhua > Hualong County > Minhe County > Ledu County.[Conclusion] The ecological environment and the resource endowment not only seriously restrict the development of the social economy

but also have a remarkable impact on the ecological vulnerability.
