| Abstract: | Based on the new technique means of RS,GIS,GPS,etc.,this paper analyzes the information of land use change in Shiping county by using high resolution satellite imagery of 2005 SPOT-5.The result shows that the area of Shiping county is 3 041.37km2,the current magistracy area increases 0.53km2,comparing with the renew land investigate of 2004.The agriculture land use is the main type of land use,which area amount to 25.40 536 104hm2,account for 83.53% of total land area.Analysis from the land conversion information,agriculture land use is converted to construction land;the unused land is converted to construction land and agriculture land use.According to land use conversion,farmland is mainly converted into construction land and garden land,while the unused land is converted into the farmland and garden land.The farmland,garden land,residential dots,the factory land and mineral land,land for transportation is the increasing trend in area,while the woodland and unused land is in the decrease trend in area.The slope information of land use change shows that each slope class farmland area has in the decrease,reducing farmland area totally is 1 705.02hm2,among them farmland areas of slope degree is ≤ 2 °and slope degree is to 6 °-15 °is decrease at most,distinguish to 407.049hm2 and 765.037hm2.The dry land area increases 7141.156 hm2,the dry land of the slope ≤ 2°,dry land areas of slope degree in scope of 25-35 is decreased,while dry land area of rest slope class all has the increment.The land renew inquisition by using high satellite imagery can effectively understand the trend and current situation in Shiping county,check the land use construction,adjust the land supply,and provide the thorough foundation data for scientific land use manage. |
