随着社会的快速发展，人类活动的日益频繁，地球表面发生了翻天覆地的变化。遥感技术以其独特的优势成为土地利用调查和变化研究的重要技术手段。本文以淮安市1995年和2006年的TM遥感影像为主要数据，依据土地利用类型的光谱特征，采用NDVI，NDWI，NDBI和非监督分类方法分别提取耕地、林地、草地、水体和建筑用地类型，并对提取结果从结构和变化角度进行分析。结果证明：1）依据地物光谱特征，采用不同模型分别提取土地利用类型的方法切实可行；2）淮安市是一个以农用地为主、水资源丰富、城镇化水平较低的地区；在1995～2006年间，耕地、水域和草地分布呈减少的趋势，林地和建筑用地呈不断增加的趋势。

Society rapidly developing and human constantly acting , the surface of earth has been taking place great changes .Remote sensing on unique advantage becomes the important technical means of land -use survey and change .TM remote sensed images of Huai′an in 1995 and 2006 as mainly data, spectral characteristic based on , cultivated, forest, meadow, water and build -up land were respectively extracted by the methods of NDVI , NDWI, NDBI and unsupervised classification .Moreover, the structure and change of land-use was analyzed based on the extracted consequence .The results show that the method is feasible which the types of land-use are extracted with different models on spectral characteristic .And Huai’an is a region with mainly agriculture constitution , abundant water resources and lower urbanization .In the study period of 1995 to 2006 , cultivated land , water and meadow appear the decrease trend and forest land and build -up land appear the increase trend .
