| 中文摘要: |
| 利用遥感资料获取土地利用信息，并采用GIS的空间分析手段提取土地利用分类信息，以计算生态耗水。对伊犁河流域下游生态耗水进行分析，根据已有的地面资料和有关研究成果，计算了流域下游的现状生态耗水及农业灌溉耗水。结果显示，该地区的农业耗水量呈上升趋势，下游人工生态耗水及农业灌溉耗水所占比例过大。表明水资源开发利用不合理是造成下游生态劣变的根本原因。 |
| 英文摘要: |
| The ecological water consumption and agricultural water consumption in downstream of the Yili River basin were analyzed by means of remote sensing and geographic information system technology．The land use information was obtained by remote sensing and the space analysis function of GIS was utilized to classify the land use for calculating the ecological water consumption according to different water demand．The current situation of water consumption was calculated based on the data verified by ground situation．The result shows that the agricultural water consumption tends to increase in this area,the proportion of artificial ecological water consumption and agricultural water consumption is too large．It verifies that the unreasonable water development of water resources is the main cause affecting the ecological deterioration of this area． |
