The Superficial Analysis Of The Background Of The Water And Soil Conservation And Plan On Resuming Ecological Environment In West Mountain Area Of Gui Zhou

Water and soil conservation is serious in Guizhou provinces,especially in the western karst mountainous areas in Guizhou,and the results will lead to land desertification.The reason is mainly in karst mountainous areas with their own special geological and geographical background and the irrational production of human activities.This article from the western Guizhou karst mountain meteorology,hydrology,geology,topography,and other human actwities,to discuss the background of karst mountainous area of water loss and soil erosion in western Guizhou Province,on the basis of this focus on analyzing the western Guizhou karst landforms different types of mountain areas to the extent of soil erosion Impact,while a different type of landscape areas of the ecological environment management measures.Through analysis and research,the following understanding:1.Guizhou is located in the western subtropical,mild climate,abundant rainfall,light moderate rain of the same quarter,a humid subtropical monsoon climate zone.Topography of the region due to height difference,complex terrain,climate which has complexity and diversity of characteristics,there are also differences in rainfall,frequent and often heavy rain intensity,easy to produce soil erosion.2.Western Guizhou in surface water system development,the flow of water,drainage area,is the carrier of soil erosion,water and soil conservation on a hazard.3.The main development of the western Guizhou Carboniferous,the Permian and Triassic carbonate rocks,carbonate rocks the result of karst,resulting in karst surface rocks-the bond between the soil of poor water and soil is poor.And easy to produce soil erosion.4.Guizhou frequent geological tectonic movement,rock crushing and fold,more undulating terrain,surface runoff easily to soil erosion.5.Western Guizhou widespread carbonate formation of various karst landscapes,different karst landforms on the impact of varying degrees of soil erosion.Of which:karst basin margin,peak forest valley,Fengcong shallow depression,Fengcong Fengcong valley and mountain areas, erosion and more for the micro-level degrees-moderate;Fengcong deep depression and Fengcong Canyon area,the extent of soil erosion and more For the strong-intense.In the same type of landscape,with an average annual erosion of the slope and the slope length increased;pure limestone bedrock for the more impure limestone soil(like clouds limestone,shale-limestone,etc.) of the soil Layer,its high volume of soil erosion.6.Irrational human activities will disrupt the ecological balance,generate soil erosion is a major factor.7.For different types of karst topography areas of natural and man-made environment,the corresponding eco-environmental improvement measures.
