Abstract: The alpine area of Northwest Yunnan is one of ecological fragile and environment sensitive zone of China,and it is very difficult to recover the environment naturally and manually if the soil are damaged during the mining exploration.This paper takes Pulang copper mine as an example to research the land rehabilitation technologies and methods by doing fieldwork and data analysis.The conclusions are:① the restrictive factors of soil rehabilitation alpine area of Northwest Yunnan are complicated ecological system diversity,high altitude,cold climate,Alternate Drying-Wetting and freezing-thawing cycles;② the land rehabilitation technologies are experimental study,topsoil stripping and disposal,land leveling and soil transporting,Slope Treatment,soil dressing,vegetation recovery and so on.
