Study On Land Use Change And Driving Force Of Qinshui County

Land Use and Land Cover Change is an important field of the global change research, and the driving force of land-use change research is one of the most important roles of the research.In the process of social development,due to natural factors and social and humanity factors and the economic factors,the Land use structure and the quality of land resources of different regions is changing, meanwhile the changes of the regional environment, ecological balance and global environment also are affected. So the study of the changing process, laws and driving factors of the Land use, is not only the important basis for the ecological environment and rational development of land resources, but also for the environment and ecological balance.The paper uses Qinshui country as research area and researches the key driving force of Qinshui country Land Use and Land Cover Change, it scientifically find outs the main driving force which affects the changing land use. And it provides a scientific basis for its rational development, utilization of land resources.This paper, which is based on the data from2002to2011of Qinshui country land use, presents the land use and the number and structure change of land use, and mainly studies the scale and speed of land use. It gets that the occupied area of the cultivated land, woodland, urban and industrial land, transportation land and water facilities increased976,3480,780,631,1408hectares, increasing by0.31%,0.29%,1.72%,11.49%and50.34%. The garden, grassland and other land area decreased1370,23590,1630hectares, decreasing by4.78%,9.33%and1.96%. In summary, the largest increased occupied area at Qinshui County was the transportation land, and the grassland area occupied the largest reduction. Cultivated land, forest land and other agricultural land occupation remained basically unchanged.Based on the former, anglicizing the driving forces, it mainly uses qualitative analysis and quantitative to analysis the driving forces. The change of land use not only is restricted by nature factors such as climate, soil, hydrological and so on, but also is affected by social and economic factors such as population growth, the first industry, the second industry and so on. In the paper, quantitative analysis includes analytic hierarchy process and grey correlation analysis, grey correlation analysis is through the computed correlation between the driving factors and various types of land, to determine the main factors affecting land use change. Analytic hierarchy process determines the main driving factors of land use change.Research shows that the county’s population is the main driving factors of the QinShui country land change. The relationship is close among agricultural land, the county’s population, total power of agricultural machinery and the total grain output. Water facilities, the state investment and industry are closely related, unused land as rising the level of mechanization is developed, using for improving food production, and meet the needs of the growing population.Finally, establishing multi linear regression model predicts future different lands as for the structure of the Qinshui county land use is not rational, unused land is too large, the construction land is not intensive, and the contradiction between land supply and demand is more serious problem. So some suggestion are raised, such as strengthening the management of land use planning, optimizing the structure of land use, developing the land use potential and increasing investment in science and technology.
