摘要

草原是北方生态系统和自然资源的重要组成部分,也是农牧民赖以生存的基本生产资料和生活资料,而生态安全是拉动地区经济社会发展的重要引擎,尤其是对于生产总值常年位居内蒙古第一的鄂尔多斯市来说,经济发展和草原生态安全的平衡便变的弥足重要.本文根据前人研究和本地实际情况,运用PSR模型构建鄂尔多斯市草原生态安全评价体系,然后利用熵权法计算指标权重,并通过收集2018-2022年的具体数据进行分析计算,结果显示鄂尔多斯市5年间草原生态安全指数呈整体上升的态势,表明其草原生态安全情况整体为向好趋势,但期间起伏较大.2018-2021年整体呈下降趋势,2022年有所好转,5年中草原生态安全指数较为不稳定.鉴于此,本文分析影响安全指数的关键因素,并提出具有针对性的对策建议来提升草原生态安全,以促进区域可持续发展.

Abstract

Grassland is an important component of the northern ecosystem and natural resources,as well as the ba-sic means of production and livelihood for farmers and herdsmen.Ecological security is an important engine for driving regional economic and social development,especially for Ordos City,which consistently ranks first in Inner Mongolia in terms of GDP.The balance between economic development and grassland ecological security becomes increasingly important.Based on previous research and local conditions,this article uses the PSR model to construct an evaluation system for grassland ecological security in Ordos City.Then,the entropy weight method is used to calculate the weight of indicators,and specific data from 2018 to 2022 is collected for analysis and calculation.The results show that the grassland ecological security index in Ordos City has shown an overall upward trend over the past five years,indicating that the overall grassland ecological security situation is improving,but with significant fluctuations during this period.The overall trend from 2018 to 2021 showed a downward trend,with some improvement in 2022.However,the grass-land ecological security index remained relatively unstable over the past five years.In view of this,this article analyzes the key factors affecting the safety index and proposes targeted countermeasures and suggestions to enhance grassland ecological security and promote regional sustainable development.
