文登市土地利用/覆被变化研究

主要利用1986年土地利用类型矢量数据和2000年TM影像,研究文登市城市快速发展所发生的土地利用/覆被变化,研究结果表明：文登市土地利用以旱田、建设用地及林地为主,14a来,随着经济建设的发展,水田、旱田、林地、草地面积增加,其中草地及林地面积增加最多,分别为7.61km2和6.20km2,建设用地及水域面积减少。土地利用转移过程中,旱田7.95 km2转为林地,8.40 km2转为草地,水域向旱田、草地和建设用地分别转化5.66 km2、0.69 km2和0.45 km2。最后提出了土地利用可持续发展建议。

Research on the LUCC of Wendeng City

This paper mainly researched on the LUCC of Wendeng City Caused by the rapid urban development with Land use vector data of 1986 and TM data of 20001 The results showed that： dry land, building land and forest constituted the main land usetypes; during the past 14 years, paddy, dry land, forest and grass increased, with grass 7.61km2 and forest 6. 20km2 , while building land and water decreased. From the land use transition matrix we knew that： 7.95 km2 dry land transformed into forest and into 8.40 km2 grass, 5.66 km2 water transformed into dryland, 0.69 km2 into grass and 0.45 km2 into building land. In the end , the paper put forward the sustainable land use development proposals.
