Depression In Soil And Water Resources And Utilization Of Matching Structure In Typical Karsts Peak Cluster Depressions Of Guizhou

China karsts mountains as a relatively unique geographical units, karsts landforms, mountain and more steep, humid in south China under the most typical of the ecologically fragile areas, especially low-lying areas karsts more fragile ecological environment, have the tendency deterioration, the majority of low-lying areas karsts soil erosion and land desertification are compounded including desertification area has reached 37,500 km2, the obvious contradiction between people and land. At the same time, low-lying areas karsts peak cluster of socio-economic development has stagnated, the main socio-economic development indicators rank the rearward position. As strong karsts development, natural disasters, population growth pressures over the environmental capacity of karsts region itself, a serious degradation of the ecosystem and people's living standard is low, economically backward, in order to survive, people have to predatory exploitation of land, agricultural development and utilization of traditional methods (such as deforestation, land reclamation slope) and the extensive cultivation of management has also caused further deterioration of ecological environment, the deterioration of the living environment, so that relying solely on agricultural income of farmers living more poverty, a vicious circle, In order to fundamentally solve the ecological environment of karsts mountainous areas and improving people's living standards. In this study, Guizhou peak and depression in a sample of typical karsts area, from water and soil resources matches the structure of space-time as a starting point, the analysis of ecological factors peak and depression, and peak and depression based on the structure of the ecological environment, Construction of the matching factors of karsts peak and depression and calculation model of soil and water, in complying with the systematic, comprehensive benefits of spatial scale effects and the premise of the principle of priority, the use of water and land evaluation model in the study area match the level of water and soil were evaluated, and affect the results depth analysis of the factors and factor analysis for the influence on the proposed match Guizhou peak and depression in the level of land and water optimization five large mode,and the corresponding countermeasures.This study sought to analyze the study area by land and water matching the typical peak and depression factors, in line with the principle of local conditions, summarizes the peak and depression of the store water appropriate technology and resistance to early to avoid water logging and rational utilization of water resources in the optimal utilization. This study is a karsts area in the development of cutting-edge academic issues, not only of theoretical significance, but also for different regions of Guizhou karsts peak and depression in the region to provide reference for sustainable development.
