中文摘要	本文简要介绍了利用遥感和地理信息系统技术进行黄河上游及源头区生态环境质量综合评价中，评价因子的获取及其分值和权值的确定，评价模型的建立及评价等级的划分。评价结果表明，该区环境质量具有垂直分带规律，人类不合理的经济活动是影响环境质量的重要因素。
英文摘要	This paper mainly focused on general evaluation of ecological environmental quality in the up-stream and headwater areas of Yellow River by means of RS and GIS technology. It determined informa-tion acquiring method of 13 evaluating factors including plant coverage, land desertification, soil and water loss, and caloulated ratio value and weight of these factors. It also focused on foundation of assessing mod-els, partition of assessing class, and classified the upstream and headwater areas of Yellow River into four ecological subregions such as Datong Mountain-Laji Mountain scrubby grassland ecological subregion, Gonghe basin grassland-desert ecological subregion etc. Analyzed main environmental problems in each subregion, and generally evaluated environmental quality of subregions as well as the whole region for comparison. The results indicated that the environmental quality of the region shows a vertical distribution law and the primary factor affecting water and soil loss, plant degradation, quick expansion of desert areas in headwaters of the Yellow River is the irrational economic activities of human being.
