摘　　要：分析和评价蓄水工程的环境状况,可为生态环境保护、区域社会经济协调发展提供科学依据。本文以内蒙古自治区乌拉盖水库为例,分析了1998-2022年研究区土地利用、植被覆盖、水网密度、土壤侵蚀等多个生态环境因子的时空变化,并采用生态环境状况指数法对其生态环境状况进行评价。结果表明,25年间乌拉盖水库研究区耕地面积减少,而林地、草地面积显著增加;水网密度呈现波动式增长;土壤侵蚀有加强的趋势。乌拉盖水库生态环境状况指数多年来维持在80以上,生态状况始终处于最高等级优等,2018年以后生态环境状况指数上升到90左右,生态状况表现出波动中不断向好的变化特征。研究成果为以乌拉盖水库为代表的内陆河流域蓄水工程建设与管理提供决策参考,促进区域水资源合理利用,推动生态环境可持续发展。Evaluating the environmental conditions of water storage projects offers a scientific basis for eco-environmental protection and regional socio-economic development.This study analyzed the Wulagai Reservoir in the Inner Mongolia Autonomous Region as an example to analyze the spatiotemporal changes in multiple ecological and environmental factors such as land use,vegetation coverage,water network density,and soil erosion in the study area from 1998 to 2022.Using ecological environment status index method,we evaluate environmental conditions.The results showed that over the past 25 years,the area of cultivated land in the Wulagai Reservoir decreased,while the area of woodland and grassland increased significantly.The density of the water network showed fluctuating growth,and soil erosion intensified.The ecological environment status index of Wulagai Reservoir remained above 80 for many years,indicating excellent ecological conditions.After 2018,the ecological environment status index rose to around 90,and the ecological status showing continuous improvement despite fluctuations.The findings provide decision-making support for the construction and management of water storage projects,exemplified by the Wulagai Reservoir,and promote the rational utilization of regional water resource and the sustainable development of the ecological environment.
