Study On Allocating Land Of Production, Living And Ecology In Burang County Of Ngari Prefecture,tibet

Burang county, located in the southern Tibet and neighbouring India and Nepal is a typical border area in the southwest of China.This article made some innovations in land types classification and the traditional configuration method. And we established the land classification system with the characteristic of Burang county. The paper aimed to put forward a suitable land use allocation method for frontier regions by researching the typical areas.In this paper, based on the principles of optimal allocation of land use, the location theory and the viewpoint of system theory, the production, living and ecology land configuration issues of Burang county were analyzed. At the same time, adhering to adjust measures to local conditions, highlighting local land use characteristics, how to carry on the land classification and the optimization of land structure and number based on the local characteristics of border regions were discussed. Burang County ecological land consists of forest land, grassland, water area and natural reserve.Grassland ecological functions both at the same time with production function. The ecology land had the characteristics of high vulnerability, naturalness, and the problems of structural imbalance and many natural disasters. Survival land for farming and grazing to supply food had the characteristics of coarse texture and must be irrigated, and it had nutrient imbalance and single planting structure problems. Life land formed urban and rural construction land, the bordertrade development of land and natural reserve, with certain regional advantage. Development lands distributed in the border area, was advantageous for the development of border trade but had the problems of low economic output and weak development foundation. This paper mainly applied the landscape pattern index to analyzes landscape pattern of ecology land. The ecology land, urban and rural development land, tourism land-use of Burang county were forecasted and analyzed by the grey GM(1,1) prediction model, the methods of demand forecasting. For Burang county analysis of ecological land, land for life, the production of land forecast. We got the land configuration optimization scheme of Burang county finally.In Burang county designated ecological land, Prohibited development zone, ecological wetland reserves and ecological restoration area. To draw the "Ecological line" establish ecological security barrier to better protect the ecological environment and protection and rational utilization of biological resources.Land for life designated for life "development line". The land for urban and rural development, development of border trade, divide the land for traffic and water conservancy was carried out respectively and layout,use of border location advantages, focus on developing land border trade. For production sites designated "lifeline",based on the prediction, such as food demand forecast to determine the Planck county land for basic survival needs. Designated alvin county living land quantity, to ensure the safety of food.
