Abstract


Land resource is a resource for human survival, has a material foundation and scarcity. Land-use change and socio-economic development between very closely related, along with the accelerated process of urbanization and the rapid development of the socio-economic, how scientific, rational, and efficient use of land resources, has become the primary regional socio-economic development needs to face and solve problems. Even poverty and backwardness, less more alpine mountains of northwestern Yunnan, its socio-economic development of the region, remains to be fundamentally land resources development and utilization as a safeguard. Typical counties in northwest Yunnan alpine mountains - Ninglang County, for example, through the county land use change and socio-economic development of the relationship between research, to clarify the association of economic development on the land use dynamic change and driving mechanism, help correct processing and coordination of the entire alpine mountains of northwestern Yunnan land resources and socio-economic development of the relationship between the development of socio-economic development decisions for the government to provide a scientific and rational-oriented and based on. The article first analyzes the theoretical basis of the study of land-use change and socio-economic development of the relationship between domestic and foreign scholars study the relationship between the two, and the progress made. Specific to Ninglang, articles collation and analysis of the various types of land change survey data 1996-2008 and analysis results show that, Ninglang significant land use change: (1) an increase of agricultural land 3089.87 hm 2 years The average increment of 237.68 hm ~ 2. (2) construction land increased by 105.45 hm ~ 2, the average annual increase in the amount of 8.11 hm to 2. (3) reduce unused 3195.32 hm ~ 2, the average annual reduction of 245.79 hm to 2. Factor selected based on principal component analysis ideas and requirements, as well as Ninglang existing information, the main socio-economic impact of land use change impact analysis of 13 factors, by the SPSS software for data processing principal component analysis, and combined with the qualitative analysis, summed drawn to the impact Ninglang land use change between 1996-2008 years the main driving factor for population growth, economic development as well as national and local policy three major factors. The combination of the three main driving force of arable land for construction, garden land type area change correlation analysis and fitting optimal linear regression equation drawn between the various types of land-use area change and socio-economic development of both. The results show that: (1) land for construction of the expansion of the total population increase was a positive correlation, while negative correlation between the decrease in arable land and an increase in the total population. (2) the close relationship between the land-use change and economic development, mainly in: (1) construction land scale expansion and GDP growth, three showed a significant positive correlation between the increase in fixed-asset investment and the secondary and tertiary industries output increased; ② proportion of primary industry reduction associated with the reduction of arable land, a positive correlation; (3) garden-scale expansion of advancing the economic development of agriculture and rural per capita net income growth, garden scale with total agricultural output and farmers' per capita net income was the same to the positive correlation. (3) has an important impact on the national and local policies on land use. Especially since 2000, the implementation of the western development strategy (grass) Engineering Ninglang reduction of arable land, but significantly increased parkland and woodland. Finally, the article on the the Ninglang socio-economic development and land use the relationship trend forecast. Forecasting method of gray system, linear regression equation to predict the trends of the main socio-economic indicators and county land-use planning period, land use demand will contribute to the economic development of macroeconomic forecast Ninglang planning period. .
