Analysis On Land Use Change In Lushan Nature Reserve And Surroundings In Jiangxi, China

The study on land use change at nature reserve is effective means of evaluating environmental quality and protection benefit. With RS and GIS technology, this paper made the nested analysis method to examine the land use changes of Lushan Nature Reserve during2000to2009, including areas changes, conversion modes and landscape pattern changes, and discussed the driving factors of the changes. The results showed that:1. At Lushan Nature Reserve, the area of forest had a net increase of1837.71hm2and the area percentage increased from65.31%to71.21%. The area of bush and farmland decreased1670.40hm2,302.13hm2specifically. However, during the same period at the Lushan Nature Reserve’s periphery, the area of forest had a net increase of1667.34hm2and the area percentage increased from13.54%to15.52%. The area percentage of bush and farmland decreased2.81%,3.20%specifically;2. Vegetation at Lushan Nature Reserve is experiencing positive secondary succession, meanwhile, retrograde secondary succession is occupying the dominant position outside of the Lushan Nature Reserve, because of the high-intensity human disturbance;3. On landscape level, Nature Reserve has lower degree of fragment and higher diversity than its periphery. However, in the study period, the degree of landscape fragmentation intensified and diversity increased within and outside protected areas, the landscape controlled by some types is weaken;4. All kinds of natural and geographic process caused water change within and outside protected areas and bare rock/bare ground change outside protected areas. A variety of government decision, demographic changes and tourism development were the drivers of farmland and built-up area at Lushan Nature Reserve and its periphery.
