Land Use Change And Sustainable Development Study Of Weiwu Section Of Qilian Mountains National Park Based On GIS

The report of the 19 th National Congress of the Communist Party of China points out the establishment of a natural reserve system with national parks as the main body.In recent years,strengthening the establishment of national parks has become a research hotspot of geography,ecology and environmental science.Based on the “theory of gold mountain and green mountain”,ecological sustainable development theory and human land relationship theory,this paper takes the remote sensing image data in 1995,2000,2005,2010 and 2015 these five years as data sources to study the land use change of Wuwei section of Qilian Mountains National Park by means of RS and GIS.The analysis of the land use change in Wuwei section of Qilian Mountains National Park from 1995 to 2015 shows that:(1)The forest land and grassland are mainly distributed in the southeast of Wuwei section of Qilian Mountains National Park,and unused land are mainly distributed in the northwest.(2)The land use is mainly the forest land and grassland,and the average area proportion of both is more than 42%.(3)The farmland increases by 0.3% and the dynamic degree is 0.015%;the forest land decreases by 0.55% and the dynamic degree is-0.028%;the grass land decreases by 0.09% and the dynamic degree is-0.005%;the water body decreases by2.66% and the dynamic degree is-0.133%;the construction land increases by 6.8%and the dynamic degree is 0.342%;while the unused land increases by 2.05% and the dynamic degree is 0.103%.(4)The main transfer sources of the farmland are grass land and forest land;the main transfer sources of the construction land are forest land,farmland and grass land;the transfer of grass land is forest land,unused land,farmland,water body and construction land;and the transfer of forest land is grass land,unused land,farmland,water body and construction land.(5)The dynamic degree of comprehensive land use is 0.1%,and the comprehensive conversion rate of land use is relatively low.(6)The Weiwu section of Qilian Mountains National Park is divided into core protection area and general control area;the farmland and the construction land in the core protection area respectively increases by 0.86% and 29%.Based on the problems of the reduction of natural landscape and the impact of human activities on core protected areas in Wuwei section of Qilian MountainsNational Park,this paper puts forward countermeasures for sustainable development of Wuwei section of Qilian Mountains National Park:to restore the natural landscape,to prohibit all human activities in the core protection area,to develop ecological agriculture and animal husbandry and ecotourism in the general control area,to improve public participation.
