| 摘 要： | 利用环渤海区域1985年、1995年和2000年3期TM卫星遥感解译数据，在GIS和景观格局分析软件支持下，对该区域1985年~2000年的土地利用景观格局及其变化进行了模拟分析。结果表明: 耕地是区域主导的景观类型，1985年、1995年和2000年耕地分别占景观类型总面积的55.96%、53.70%和55.64%；林地、建设用地是区域优势景观类型，林地分别占景观类型总面积的21.12%、22.13%和20.95%，建设用地分别占景观类型总面积的10.48%、11.83%和11.70%；1985年~1995年、1995年~2000年两个时期，林地和建设用地景观的变化趋势是先增加后减少，与耕地景观变化趋势正好相反，在一定程度上反映了耕地与林地、建设用地景观类型之间的互动转换关系；两个时段土地利用景观斑块数、斑块密度、边界密度、多样性指数、聚集度和均匀度指数的变化表现为先增后减的过程，分维数、蔓延度指数和分离度的变化呈现出先减后增的过程。1985年~2000年土地利用景观斑块数、分维数、多样性指数、分离度和均匀度指数处于降低趋势，而斑块密度、边界密度、蔓延度和聚集度指数呈现出增大趋势，反映了该区域内土地利用景观类型之间存在较大差异，各组分的复杂性降低，大斑块增多，各景观之间的不均匀性增大，不稳定性增强。

| Abstract: | It is generally believed that regional land use is the base of human activities, and the l landscape change can generally reflect the mutual influence between human and nature. On the macro background of the rapid economic development over eastern coastal areas of China, it is of necessity to examine regional land use and landscape changes, particularly characteristics and spatial distributions of typical land use types such as arable land, woodland, and construction land. Based on three scenes of Landsat TM imageries acquired in 1985, 1995 and 2000, and geographic information system (GIS) and related landscape analysis techniques, the authors investigated and simulated in detail spatio-temporal pattern changes in landscape types over the area surrounding the Bohai bay from 1985 to 2005. It was concluded that arable land was the dominant land use type over the area, and the proportion of arable land was 55.96%, 53.70% and 55.64% in 1985, 1995 and 2000, respectively. Woodland and the land for construction dominated the study area for this period. The proportion of woodland showed to be 21.12%, 22.13% and 20.95%, and the proportion of construction land was 10.48%, 11.83% and 11.70% in 1985, 1995 and 2000, respectively. It was found that the woodland and construction land showed an increasing trend during 1985-1995 while decreasing during 1995-2000, contrary to the variation trend for arable land in the two periods. It was also showed that there exited a significant interaction between the arable land, and woodland and construction land for different periods. Values of landscape indices consisting of NP, PD, ED, SHDI, AI and SHEI showed an increasing trend during 1985-1995 while decreasing during 1995-2000. Values of PAFRAC, CONTAG, and SPLIT were decreasing during 1985-1995 while increasing during 1995-2000. It was also found that during 1985-2000, the landscape indices comprised of NP, PAFRAC, SHDI, SPLIT and SHEI were decreasing, while PD, ED, CONTAG and AI increased. This showed that there were large differences in variations of all landscape types over the study area. In general, the significant characteristics of changes in regional landscape pattern were that complexity of components for each landscape type reduced and a large number of patches accordingly increased. The heterogeneity and instability increased for each landscape type surrounding the Bohai bay during 1995-2000. |
