该文以1999年及2009年岑溪市土地利用数据为来源，在GIS的支持下，分析了10年来研究区内的土地利用变化的时空特点及其转化过程，结合土地利用综合指数、耕地垦殖指数、植被覆盖指数、景观破碎度指数评价了土地利用变化的生态风险。研究表明：研究区域内10年间土地利用类型发生了复杂的相互转换，其中林草地、建设用地和耕地为研究区内变化面积最大的3种土地利用类型；受经济快速发展和城市化进程加快的影响，土地利用的广度和深度不断增大，全市土地利用趋于破碎化，土地生态风险程度有所增加。

Based on information of land use in 1999 and 2009 in Cenxi city, on the support of GIS technology, spacial characteristics and transition of land use change in research area in 10 years have been analyzed. Combining with composite index of land use, land reclamation index, vegetative covering index and frag- mentation index, land ecological risks are evaluated. It is showed that complex transformation has been happened among all kinds of land use types in ten years in research area. Among them, the squares of for- estland and grassland, cultivated land and construction using land changed best. Accompanying with rapid development of economy urbanization, the extent and depth of land use will be increasing, and land use weill tend to be fragmentized, which will obviously increase the degree of land ecological risks.
