摘要

[目的] 分析和评价宁夏回族自治区生态环境变化特征

为该地区生态环境建设提供理论依据。[方法] 构建基于"压力-状态-响应"(PSR)模型的生态环境综合评价体系

应用熵值法系统评价宁夏地区1986-2012年生态环境变化及其特征。[结果] (1) 1986-2012年

宁夏地区生态环境压力呈波动增加趋势

需加强实施产业结构调整

节能减排

循环经济等措施的力度。伴随着气候的暖干化

未来宁夏地区生态环境建设将面临新的挑战; (2) 宁夏地区生态环境状态得分呈波动增加趋势

生态环境逐渐趋于好转; (3) 宁夏地区生态环境响应得分呈增加趋势

说明宁夏地区生态环境治理与保护投入水平提高;在相关生态建设措施的实施下

人类活动对环境的压力有所减少

生态环境质量逐步好转; (4) 宁夏地区生态环境综合得分呈波动上升趋势。[结论] 近27 a来

宁夏地区生态环境质量总体提高。

Abstract

[Objective] To analyze the characteristics of eco-enviroment evolution in Ningxia Hui Autonomous Region in order to provide theoretical basis for eco-environment construction.[Methods] By building the eco-environmental evaluation system based on the press-state-response model

the characteristics of the eco-environment in Ningxia Hui Autonomous Region from 1986 to 2012 were evaluated.[Results] (1) The pressure of eco-environment trended to increase in Ningxia Hui Autonomous Region during 1986 to 2012

so it should strengthen the implementation of industrial restructuring

energy conservation and emission reduction

recycling economy and other measures. (2) The ecological environment showed a trend of increased volatility

and the ecological environment improved gradually. (3) The ecological response scores of Ningxia Hui Autonomous Region tended to increase

it indicated that the investment of govern and protection level increased in eco-environment in Ningxia Hui Autonomous Region. In the implementation of the relevant eco-building measures

the pressure of human activities on the environment decreased

the quality of ecological environment improved gradually. (4) The ecological environment comprehensive score of Ningxia Hui Autonomous Region showed a fluctuated upward trend. [Conclusion] During the past 27 years

the quality of ecological environment is increasing in Ningxia Hui Autonomous Region.
