Research On The Driving Forces Of Land Use/Land Cover Change In Hanyuan

Land is material basis of the human survival and development,is the most basic natural scarcity of non-renewable resource.In Global Environmental Change ploblem, Land use/cover change can be said that the process of natural and human issuesmost relevant to cross,therefore, the LUCC as a lot of attention and focus of research scholars. International Geosphere-Biosphere Programme (IGBP) and the Global Environmental Change Programme in the field of humanities (HDP) jointly proposed a"and use and land land cover change"research program, Ministry of State Land Resources addenda jointly formulated by IGBP and human field research project of global environmental change and tries to get in line with it as well as reflects the Chinese characteristics. Currently,the research on the LUCC in Hanyuan has not expanded in depth, so in this paper, to Hanyuan as the research object. With the socio-economic statistics from 1999 to 2009, adopt the number of land-use change model, the land use change mode,the land use of space analysis framework change, reveals the land use/cover changes in spatial variation in Hanyuan, and under the guidance of SPSS 18.0, for a review of the land use/cover change in the quantitative analysis of human driving force, and qualitative describes the policy and cultural factors drivering.Major study conclusions as follows:From the current situation of land use in Hanyuan in 2009, land use constituted by woodland and unused land. From the perspective of land use structure in the towns, has obvious regional differences, including farmland, woodland and urban village, and independent industria and mining land is most obvious..Through the right analysis on the structure of land use changes, the number of land use change, the land use change and land use of space analysis of changes in patterns, can be seen in the various land use types in Hanyuan, the largest decrease of farmland, land of composite index dropped. Since decreasing arable land and construction land increasing, increasing degree of fragmentation of farmland, therefore, diversity index of land use change and evenness index larger, the dominance index smaller.On the basis of comprehensive analysis on the land use/cover change in the economic factors, social factors, and factors of technological advances in agriculture, obtained the various factors on the impact of land use change, the policy and cultural factors in Hanyuan land use/cover change also can not be underestimated in the role.From the above research found that in the process of land use main problems in Hanyuan is reduction of farmland,population growth has increased the pressure on land resources; lack of reserve farmland resources and the distribution is more fragmented; Serious damage to ecosystems, On the basis of this,giving some strategies and recommendations about the sustainable utilization of land.
