摘要
研究目的:揭示唐山市1993—2003年工业用地数量变化、时空变化特征、扩展模式和景观指数变化。研究方法:以1993年和2003年两期LandsatTM/ETM遥感影像为主要数据,借助唐山市城市土地利用现状图及统计资料,运用Erdas软件进行人机交互解译,并借助GIS软件进行分析。运用土地转移矩阵、重心转移、扩展速度、景观指数计算等方法。研究结论:(1)研究区内工业用地规模不断扩大,主要增加源为耕地。(2)工业用地空间结构发生变化,工业重心向西北方向移动。(3)工业扩展模式主要有飞地式跳跃扩展和同心圆式蚕食性扩展两种,其中以飞地式跳跃扩展为主。(4)工业用地斑块增加,平均面积减小,分形维数变大,破碎度增加,工业分布趋于分散。
The purpose of this paper is to reveal the area change, the spatial and temporal change, the expansion pattern and the landscape index change of industrial land in Tangshan. Method of man-machine interactive operation was applied to interpret LANDSAT and TM/ETM images of 1993 and 2003 with the assistance of Erdas software, the actual land use map and statistics data of Tangshan. Other methods were used as land transfer matrix, expansion rate and landscape index. The results indicate the scale of industrial land increased continuously by cultivated land conversion. The spatial structure had changed and the core area had moved to northwest. The spatial expansion patterns include exclave jumping and concentric circle nibble in which the former is predominant in this area. The industrial land distribution has the dispersive trend as a result of the increases of patches, the fractal dimensions and the fragmentation degree.
