通过3S技术与4D技术的结合,完成滇池流域DEM、DLG、DRG、DOM图的制作,为土壤侵蚀解译交互判读,进行流域自然状况及水土流失面积调查,提供客观依据;通过在滇池流域内选取具有典型代表性的小流域进行水土流失治理设计,根据小流域具体情况,分层布设样地、径流场、测流堰等监测设施,实地观测水土流失量及污染总量;通过观测分析、测算全流域的水土流失量、污染物流失量及治理措施的水土保持效益。 Through the combination of 3S technology and 4D technology, the production of DEM, DLG, DRG and DOM maps in Dianchi Lake basin was completed, interpreting and interpreting soil erosion interactively, and investigating the natural conditions and soil erosion area in the basin. According to the specific conditions in the small watershed, the monitoring facilities such as sample areas, runoff fields and weirs are stratified, and the amount of soil and water loss and the total amount of pollution are observed. Through the observation and analysis, Calculate the amount of soil and water loss, the amount of pollutants lost and the benefits of water and soil conservation in the whole basin.
