Abstract:

Land use and socio-economic development are closely linked. Even the poor high and cold mountainous in the northwest Yunnan province, with limited population and vast land, and its economic and social development still needs to rely on exploration and utilization of land resource as security. The author took a typical county in high-altitude mountainous areas of northwest Yunnan province-Ninglang Yi autonomous county for example, using the data of land change survey in the county in 1996-2008, from the quantitative point of view, to analyze the relationship and characteristics between land use change and regional social and economic development. The author fitted to cultivated land, garden and building land area change and socio-economic development, derived the optimal equation of linear regression. According to the research and analysis, the author concluded that Ninglang land use change was mainly driven by three major factors: population, economic development and national and local policy. This will help us to handle the relationship between the land resource management and economic development in high and cold mountainous northwest Yunnan province correctly, so it can offer some correct suggestions for the scientific development of local social economy.
