通过对1986、1996和2000年的TM影像解译，得到了海口市土地利用结构的变化。水?未利用的土地和森林被转化为城市？农村居民点和建设用地。通过转换矩阵分析土地利用的来源和目的地。森林、水域等自然景观受到人类活动的干扰，分维降低。耕地的分维随着面积的减少而降低。城市土地随着斑块的扩大和减少而集中。农村居民点和建设的分散，其复杂性增加。海口市总体趋势是深化和城市化。农村居民点用地侵占自然土地。城市化可能是在地方、区域和全球范围内对环境产生巨大影响的最重要的人类活动之一(Turner等人，1990年)。城市化的过程就是城市的扩张和农村向城市的转变。在中国，由于户籍和就业机会的限制，从农村到城市的移民比发达国家少。1988年，随着海口的建设和优惠政策的实施，海口吸引了大量的国外资金和其他省份的资金。作为海南省的省会和政治、经济、文化、交通中心，房地产的发展刺激了海南的城市扩张。本文研究了快速城市化过程中土地利用结构的变化。
By interpretating TM imagery in 1986,1996 and 2000, the land use structure change in Haikou city was gotten.The cultivated land? water? unused land and forest was converted into the urban? rural settlement and construction land.The land use source and destination was analyzed by conversion matrix.The natural landscape such as forest and water was disturbed by the human activities and the fractal dimension decreased.The fractal dimension of the cultivated land decreased with the acreage decreasing.The urban land concentrated with the extension and the decrease of the patches.The rural settlement and construction dispersed and its complexity increased.The general trend in Haikou city was the deepening and the urban? rural setttlement land encroached the natural land. Urbanization is perhaps one of the most important human activities that creats enormous impacts on the environment at the local, regional and global scales(Turner et al.,1990). The urbanization process is the urban sprawl and the conversion of the rural area into cities. In China owing to the limit of the registered permanent residence and the employment opportunities, the immigration from the rural residence to the cities is fewer than that of the developed countries. With the building of the province and the implementation of the favorable policies in 1988, a great amount of capital from abroad and other provinces was invested in Hai kou. The real estates development stimulated the urban sprawl as the capital and political?economic?cultural and transportation center of Hainan province. The paper studied the land use structure change during the rapid urbanization process.
