摘要

[目的] 以山西省忻州市为例，探讨能源与生态复合区生态安全预警，为区域生态保护规划及区域高质量发展提供依据。[方法] 基于PSR概念模型框架，从人口、资源、经济、环境、生态要素选取了21个指标建立了能源-生态复合区生态安全预警评价指标体系，采用熵值法确定权重，对山西省忻州市2000-2018年生态安全预警进行分析。[结果] ①2018年忻州市14县综合预警值介于0.356 2~0.587 0之间，平均值为0.491 2，预警等级处于中警至轻警范围内。其中忻府区、定襄、五台、繁峙、静乐5县（区）警情为中警状态，其余7县（市）均为轻警状态，忻州市整体生态安全并不乐观，生态安全等级较低。②2000-2018年忻州市生态安全预警值呈波动缓慢上升趋势，警情为中警等级的县减少，轻警等级的县增加。[结论] 研究区生态安全空间上呈现不均衡性，警情整体趋于改善，主要取决于系统压力中的经济、资源、环境压力趋缓。

Abstract

[Objective] Taking Xinzhou City of Shanxi Province as an example

the pre-warning of ecological security in energy-ecological recombination region was discussed

in order to provide a basis for regional ecological protection planning and high-quality development.[Methods] Based on the pressure-state-response conceptual model framework

21 indexes were selected from population

resources

economy

environment and ecological elements to establish the ecological security early warning and evaluation index system in energy-ecological recombination region. Entropy method was used to determine the weights and analyze the ecological security pre-warning in Xinzhou City from 2000 to 2018.[Results] ① In 2018

the comprehensive pre-warning values of 14 counties in Xinzhou City ranged from 0.356 2 to 0.587 0

with the average value of 0.491 2. The pre-warning level was within the range of medium to light

among which Xinfu District

Dingxiang County

Wutai County

Fanshi County and Jingle County were in the state of medium pre-warning level. The remaining seven counties were in the state of light pre-warning level. The overall ecological security of Xinzhou City was not optimistic because of its low ecological security level. ② From 2000 to 2018

the ecological security pre-warning values of Xinzhou City showed a slow upward trend. The number of counties with medium and light alarm level decreased

while the number of counties with light alarm level increased.[Conclusion] The ecological security in the research area presented unbalanced in space. The overall warning situation tended to be improved due to the decreasing pressure on economy

resources and environment in the system.
