摘  要:
以黄冈市为研究区域,利用RS和GIS技术对Landsa5 TM影像进行处理。采用监督分类方法提取了黄冈市2001年和2009年两期土地利用信息,生成土地利用类型转置矩阵,应用单一土地利用动态度和综合土地利用动态度模型分析土地利用类型的时空变化规律,并对黄冈市土地利用的未来时空变化的趋势进行了预测。结果表明,9年间黄冈市耕地、建设用地和其他类型一直处于增长趋势,耕地和建设用地增幅较大,其他类型增幅较小;林地、裸地和水体面积处于下降趋势,其中林地下降最快,其次是裸地,而水体下降较小。黄冈市各土地利用类型总变化面积大小为:其他类型>耕地>建设用地>>裸地>林地>水体>沙洲,沙洲、耕地和林地的变化速度快,其他3种类型的变化速度相对较慢;沙洲、裸地和水体的年变化率较大,其中沙洲最大。

摘  要:
By processesing landsat5 TM images of Huanggang city with RS and GIS technology, the land use information of Huang gang in the year 2001 and 2009 was extracted by supervised classification. Spatio-temporal variation rules were explored by counting area and building change matrix. Through calculating discrete land use dynamic degree and integrated land use dynamic degree, the future change tendency of land use structure in Huanggang city was forecasted. The results showed that area of cultivated land, building land and other land in Huanggang city increased in the last 9 years; and the increasing amplitude of cultivated land and building land was larger than the others. Area of forest land, bare land and water body decreased in the past 8 years; and the reducing speed of forest land was the highest among them, followed by bare land,while the water just decreased a little. In addition, the absolute change area of land use types ranked as otherland >cultivated land >building >bare land >forest land >water body >sandbar. Change speed of sandbar, cultivated land and forest land was higer than the others; and the annual change rate of sandbar, bare land and water body was all comparatively higher, among which sandbar was the highest.
