摘要
为研究河西走廊地区内陆河讨赖河流域水生态健康情况,依据有关评价技术规范,选取人口密度、城镇化率、干旱指数等20个评价因子,采用灰关联和模糊综合评价两种方法对讨赖河流域水生态进行评价,结果表明,讨赖河流域水生态环境处于较健康状态。评价结果可为区域生态环境监测与评估、水资源可持续利用、河湖保护开发等提供技术参考和决策依据。
To study the water ecological health of the Taolai River Basin in the Hexi Corridor inland river area,based on relevant evaluation technical standards,20 assessment factors are selected,including population density,urbanization rate,and drought index.The paper employs two methods,grey relational analysis and fuzzy comprehensive evaluation,to assess the water ecology of the Taolai River Basin.The results indicate that the water ecological environment of the Taolai River Basin is in a relatively healthy state.The evaluation results can provide technical references and decision-making basis for regional ecological environment monitoring and assessment,sustainable utilization of water resources,and the protection and development of rivers and lakes.
