通过野外实地考察结合遥感技术手段开展珠海市三灶区城市水土流失重点调查。三灶区水土流失类型以人为侵蚀为主，主要是由于开发平台建设、取土采石和修筑公路造成，侵蚀类型复杂多样，多沿交通道路两侧以及城市建成区周遍地带分布，侵蚀模数相差很大，最大侵蚀模数和最小侵蚀模数之间相差3个数量级，充分反映了城市水土流失的特点。
通過野外實地攷察結閤遙感技術手段開展珠海市三竈區城市水土流失重點調查。三竈區水土流失類型以人為侵蝕為主，主要是由于開髮平檯建設、取土採石和脩築公路造成，侵蝕類型複雜多樣，多沿交通道路兩側以及城市建成區週遍地帶分佈，侵蝕模數相差很大，最大侵蝕模數和最小侵蝕模數之間相差3箇數量級，充分反映瞭城市水土流失的特點。

Soil and water loss types and their characteristics are researched by using remote sensing technology and field detection in Sanzao,Zhuhai City.Man-made erosions are the main types of urban soil and water loss,which result from high intensity human action such as platform building,mining and quarry,road construction and so on.The types and erosion modules of urban soil and water loss are many and varied.Spatial distribution of man-made erosion is mainly concentrated along both sides of road and around residential area.
