摘　　要：根据3期TM遥感影像,采用地理信息系统技术,分析了1991-2011年期间蛟河盆地内地表水的水域面积变化情况及水资源环境状况。结果表明：近20年来,蛟河盆地内的水域面积减少率达49.69%,特别是松江湖的水域面积呈持续下降趋势;蛟河盆地水资源环境的不断恶化是由多种因素造成的,其中主要因素是人类不合理活动及松江湖自然泄流。据此最终提出了蛟河盆地应加强水资源保护与建设的建议。Using three terms of TM remote-sensing images as data source , adopting GIS technology , we analyzed the surface water area changes and water resource environmental status of Jiaohe basin during 1991-2011.The results indicated that： in the past 20 years, the decrement rate of water area in Jiaohe basin reached 49.69%, especially the water area of the Songjiang Lake showed a continuous decline trend;the unceasing deterioration of water resource environment in Jiaohe basin was caused by many factors, mainly including the unreasonable activity of human and the natural aerial drainage of the Songjiang Lake .Hereby, it was suggested that the protection and construction of water resources in Jiaohe basin should be strengthened .
