Taking gis software ( arc / info and arcview ) and visual foxpro as basic plat , protracted the system maps of land resource , those basic subject maps included land use status map , land types map , soil types map , grade map and soil organic substance map , combing with former summarizing research results , built the spatial basic database of land resource ; based the spatial database , by the means of attribute table manipulation and take the map plot as basic unit to get the subject attributes of basic information , combined with social economy attribute information , built the attribute database ; take the spatial basic database as basic work , by the means of vector piles to get the land resource dynamic movement system maps , included land use status , land types and soil organic substance dynamic movement map 以gis軟件( arc info 、 arcview )與visualfoxpro為基礎(chǔ)平臺(tái),繪制完成土地資源的系列圖,包括土地利用圖、土地類型圖、土壤類型圖、坡度圖、土壤有機(jī)質(zhì)圖等基礎(chǔ)專題圖件,結(jié)合以前的工作成果,構(gòu)筑土地資源的空間本底數(shù)據(jù)庫;通過空間疊加分析,得到基礎(chǔ)單元圖斑,采用屬性表操作的方法獲取基礎(chǔ)單元圖斑的專題屬性信息,結(jié)合社會(huì)經(jīng)濟(jì)屬性信息,建立屬性數(shù)據(jù)庫;以空間本底數(shù)據(jù)庫為基礎(chǔ),采用矢量疊加對比分析的方法,得到土地資源動(dòng)態(tài)變化系列圖,包括土地利用、土地類型、土壤有機(jī)質(zhì)等動(dòng)態(tài)變化圖。
