“礼炮”号遥感图像在于桥水库流域土壤侵蚀调查及治理规划中的应用

本文论述了采用前苏联“礼炮”号航天遥感图像作信息源开展天津市于桥水库流域1:10万比例尺土壤侵蚀现状调查与制图、面积量算、分区治理规划措施等项研究工作的方法和结果。并在典型样区初步探讨了遥感调查土壤侵蚀与氮、磷元素流失关系,为天津市人民生活和工农业用水水质富营养化问题的解决提供了科学依据。

THE APPLICATION OF "SALYUT" SPACE STATION REMO-TELY SENSED IMAGE TO SURVEY OF SOIL EROSION AND PLANNING

The paper describes the method and conclusion of soil erosion survey and mapping (scale-l:100,000), area measurement and regional planning in Yuqiao reservoir basin in Tian-jing Area based on pre-USSR 'Salyut' Space Station remotely sensed image. The relationship between the soil erosion and whole nitrogen and phosphorous lost in typical sample area has been tantatively discussed, and this offered the scientific basis for the solution of eutrophica-tion of water quality in inhabitants living, industry and agriculture in Tianjing Area.
