随着人口的增长和生产的发展,城镇居民用水越来越显得紧张。特别是那些贫水地区,问题更为突出,急待开辟新水源。为此,中国科学院长春光学精密机械研究所与中国给水排水东北设计院合作,进行了城镇供水勘察的遥感应用研究。在寻找长春市大屯镇富水井位时,采用了多种空间信息复合技术,经综合对比分析后,在小面积上利用遥感技术寻找地下水源,获得了实际应用效果。一、勘察区的自然地理概况及水文地质特征勘察区大屯镇位于长春市南郊,现有居民约14000人,面积165平方公里,属平原贫水区。原有水源被污染,不宜饮用。重要解译区位于大屯镇东7公里的富强水库与八一水库之间,解译面积为60平方公里。地表呈波状起伏,黄土台地上发育的北东向沟谷即为地形形变的主要方向。
With the growth of population and the development of production, water for urban residents becomes more and more nervous. Especially in those poor areas, the problems are even more prominent, and we urgently need to open up new sources of water. To this end, Changchun Institute of Optics and Fine Mechanics, Chinese Academy of Sciences and the China Water Supply and Drainage Northeast Design Institute, carried out urban water supply exploration of remote sensing applications. When looking for the water well location of Datun Town, Changchun City, a variety of spatial information compounding techniques were adopted. After comprehensive comparative analysis, remote sensing technology was used to find underground water sources in a small area, and the practical application effect was obtained. I. Natural Geographical Survey and Hydrogeological Features of the Survey Area Datun Town, located in the southern suburbs of Changchun City, has a population of about 14,000 with an area of 165 square kilometers and belongs to the poor water area of the plain. The original water is contaminated, unfit for drinking. Important Interpretation Area is located in Datun Town, 7 km east of the rich reservoir and Bayi reservoir, interpretation area of 60 square kilometers. The surface undulation, the development of the loess plateau to the northeast to the valley is the main direction of terrain deformation.
