| 摘 要： | 以山西省晋中市榆次区为例，基于RS和GIS技术，对1990年、2000年和2010年3期影像进行了景观类型分类提取，并分析了榆次区城市土地利用建设用地增加和耕地减少与景观指数之间的相关性。结果表明：城市建设用地和耕地变化与土地利用景观格局变化的相关性明显，且随着不同时期城市化特征差异，选取的景观指数有一致的变化规律，但在不同方向上变化规律不同。景观格局指数在反映研究区各方向景观格局变化特征上具有良好的指示效应。

| Abstract: | Landscape types were classified and extracted from remote sensing images in 1990 , 2000 and 2010 , and the relative relationship between the increase of construction land, reduction of arable land and landscape index in Yuci District of Jinzhong City were analyzed based on RS and GIS technologies.The results showed that the landscape index was significantly correlated with increase of construction land and reduction of arable land , the changes of selection landscape index was concordant with the differences of urbanization features of different periods, however, the changes in different directions was inhomogeneous.Therefore, landscape pattern index is a good indicator for evaluation the temporal and spatial changes of urban expansion and landscape pattern. |
