| 摘 要： | 自然保护区生态环境破坏问题日益严重,而草地类自然保护区生态系统脆弱,一旦破坏,很难恢复,因此,对草地类自然保护区生态环境质量开展动态评价,对我国草地类自然保护区的可持续发展具有重要意义.本研究在集成分析草地生态系统生态环境质量研究的基础上,基于我国草地类自然保护区的特征,构建了包含16个指标(14个一般性指标和2个限制性指标)的草地类自然保护区生态环境质量动态评价指标体系,并将生态环境质量的动态变化情况(生态环境质量变化指数)分为7个等级,以期为科学客观地评价草地类自然保护区生态环境质量提供重要参考依据.通过案例研究看出,2010-2015年间,锡林郭勒草原自然保护区的生态环境质量变化指数为-0.7,评价等级为"显著变差".

| Abstract: | The destruction of eco-environments in China's nature reserves is increasing in severity.Moreover, China's grassland nature reserves have fragile ecosystems,which are difficult to restore once destroyed.As-sessment of eco-environmental quality is important for the sustainable development of grassland nature re-serves.On the basis of previous studies and literature on assessments of the eco-environment quality of grass-land and characteristics of grassland nature reserves in China,we established an eco-environmental quality as-sessment system for grassland nature reserves,which includes 16 indicators (14 general indicators and 2 limit indicators).The eco-environmental quality change level was divided into seven grades.Model assessment clearly indicated that the eco-environment of Xilinguole Grassland Nature Reserve had deteriorated significantly from 2010 to 2015. |
