摘　　要：以湟水流域为研究对象,利用LANDSAT8 OLI和MODSI遥感影像,基于ERDAS软件和ArcGIS软件空间分析技术,得到流域土地利用类型分布图和植被覆盖空间分布图。根据《生态环境状况评价技术规范(HJ192-2105)》,计算生物丰度指数、水网密度指数、植被覆盖指数、土地胁迫指数和污染负荷指数等,对流域的生态环境状况进行评价和分析。结果表明:流域生态环境状况一般,主要是由于西宁市城区和民和县生态环境状况指数较低。现阶段加强水资源管理和控制污染排放是生态环境治理的重点。In the Huangshui Basin,the distribution of land use type and vegetation coverage can be acquired based on the spatial analysis technology of ERDAS and ArcGIS software,using LANDSAT8TM and MODSI remote sensing image. According to the technical criterion for ecosystem status evaluation,through calculating biological richness index,vegetation coverage index,water network denseness index,land stress index and pollution load index,the feature of ecological environment is evaluated and analyzed. The results indicate that the ecological environment of Huangshui Basin is overall general level,mainly owing to the low ecological index of urban area of Xining County and Minhe County. Other County kept in good level about ecological index. Intensifying water resources management and controlling of the water pollution discharge is the key of the ecological environment governance at this stage.
