There are serious problems of soil and water loss in low mountain and hilly areas,which are caused by overgrazing,unregu-lated cutting and steep slope clearing.To solve this problem,the soil and water loss control model based on comprehensive management of small watershed can be adopted.Management measures include mountaintop closure management,mountainside conversion of farm-land to forest and slope modification control technology.Hilltop areas are closed,vegetation is restored,logging,mowing and grazing are regularly prohibited,and bare land is covered and planted.In the mountainside area,the strategy of returning farmland to forest is implemented,economic fruit trees are planted,and slope transformation technology is used to build flat farmland.In addition,we should also pay attention to the construction of water conservancy projects,solve the problem of irrigation among forests,and promote water-saving irrigation technology.These measures will help improve soil erosion in low mountain and hilly areas and protect the eco-logical environment.
