- 摘要:
- 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。
- Abstract:
- Making DEM maps by 3S technique combinations can provide objective evidence for deciphering and determining the information of soil erosion alternately.It can also give evidence for investigating the natural situation of watershed and area of soil and water loss.One of the representative small watersheds in Dianchi Lake watersheds was chosen to design the comprehensive control project of soil and water loss. Based on the situation of small watershed,monitoring installations such as the major quadrat,runoff areas, measuring weirs and so on,Field study about soil and water loss tolerance and pollution gross was conducted, through which analyze the soil and water loss tolerance and pollutant loss tolerance of the whole watersheds and the benefit of management measures.
