An Evidence Of The Grassland Agriculture Controlling Extremely Rocky Desertification In The Longquan Mountain Regions Of Sichuan Province

Rocky desertification not only led to the loss of land resources of southwest China, but also lead to water resources gradually wither, governance rocky desertification Desertification Region, is always facing the scientific issues. On rocky desertification is limited to rocky desertification genesis and treatment technology, rocky desertification genesis confined to the natural and anthropogenic factors, and ignore the background of this factor; rocky desertification control technologies are adopted afforestation to restore the vegetation mainly ignore this technical application of the initial surface defects can not be quickly covered. Rocky desertification causes and treatment strategies for the status, the Longquan Mountain in Sichuan rely on mountain villages Cliff Village as a pilot area, to carry out empirical research extremely rocky desertification of grassland agricultural management. Achieved the following main conclusions:1A clear spatial pattern of distribution by the Sichuan Longquan Mountains Desertification, drawing a distribution map based on3S technology, Longquan mountain is extremely rocky desertification is mainly located in the heart of the altitude of800m.2Pointed out that the rock desertification is although the results of the interaction of natural factors and human factors, human beings can not be regulated in the short term, the focus of the rocky desertification control according to regulate human factors, and propose policies that diverge from the context of positioning of agricultural production systems allowed, is the development motivation of the Longquan Mountains Desertification.3Although the corn, pepper and orange eucalyptus are the main tree species in the Sichuan Longquan Mountain governance rocky desertification, but found that the extremely rocky desertification of corn, pepper and orange eucalyptus can not be effective governance, the only effective treatment of mild and moderate stone desertification.4Creates extreme rocky desertification of grassland agriculture governance Longquan Mountain mode, ie, soil (manure)-Grass (Themeda grass)-Poultry (Chicken)-livestock (sheep) of grassland agriculture model, two years and eight test results show that, the model can not only by a rapid increase in the surface grass coverage and erosion control, but also to reform the Longquan Mountain mode of agricultural production to boost farmers’income, but also the ability to control extremely rocky desertification into the farmers’ production practices.5Grassland agricultural mode of governance is extremely rocky desertification effect of time and space points the opposite differences, this point comes from the governance duration and slope.
