为研究海湾区域的土地利用／覆盖空间变化特征，探析其变化影响驱动因子的作用，文章以海南八门湾为研究区域，以遥感（RS）与GIS为技术手段，提取了1988年、1998年和2009年3年的土地利用，覆盖空间格局信息，研究其土地利用变化动态度，并分析了自然驱动因素和社会经济驱动因素的作用．结果显示，研究时段内八门湾地区养殖水面、水田和果园保持较高的增长速度，而红树林、天然林和旱作耕地则呈现大面积的减少．自然因素是土地利用／覆盖基本分布格局的主导因素，而社会经济和政策约束是土地利用／覆盖分布格局变化的主导因素．文章的研究可为海湾地区土地利用管理和生态环境保护决策提供参考和借鉴依据．%For studying on the characteristics of land use and land cover change （LUCC）, and analyzing the effect of its driving factors, this paper takes Bamen bay as the study area, extracting the LUCC results throughout years of 1988, 1998 and 2009 based on RS and GIS. Then analyzing the degree of land use dynamic change, and also analyzing the rela- tionship between driving factors. Results show that the areas of aquaculture bases, paddy fields and orchards draw an ob- vious increase, meanwhile, mangroves, natural forest and farm land decline obviously. As the analyzation of the driving factors shows, the natural conditions would be the main factors for basic distribution of LUCC, and the economic develop- ment and poliey factors would be the main factors for alteration of land use. Our study could provide both reference and guidance for land use management and ecological environment protection in bay area.
