| 摘 要： | 为了充分了解热带滨海城市发展过程中景观变化特征及其影响因素,利用基于SPOT的影像数据,应用RS、GIS软件和景观生态学方法,以海南省三亚市作为研究对象,分析了2002—2012年三亚市土地利用及景观格局的动态变化情况。结果表明:(1)三亚市仍以耕地和阔叶林为主,建设用地大幅度增加,各土地利用类型有相互转移表现,2002—2012年,水田面积减少了25.75%,水库/坑塘减少6.21%;草丛、建设用地和旱地面积分别增加143.16%、86.89%和10.20%;(2)运用景观格局指数和转移矩阵分析,得出研究区域景观斑块总体数量减少,说明这期间三亚景观破碎化趋势降低,主要由于人类活动的干扰不断加强,城市化进程加快使原来分散的乡镇村落等居民集中地聚集成片,转变为城市化建筑群,从而导致了研究区域景观破碎化程度的下降。

| Abstract: | To understand the landscape change characteristics and its influencing factors in urban development process of tropical coastal city, based on the SPOT image data, with the support of RS, GIS software and landscape ecology method, the dynamic changes of land use and landscape pattern in Sanya from 2002 to 2012 were analyzed. The results showed that: (1) during the past 10 years, the main landscapes were farmland and broad leaved forest, but the construction land increased significantly, all of the landscape types had mutual transfer, such as paddy field decreased by 25.75% , reservoir or pond decreased by 6.21% ; brushwood, construction land and dry land increased by about 143.16%, 86.89% and 10.20%, respectively; (2) after landscape pattern index and transfer matrix analysis, it was concluded that the number of landscape patch was decreasing, and the landscape fragmentation was reduced, mainly due to the strengthened interference of human activities, and the speed up of urbanization process, the original fragmented distribution of residential land and building land became poly integration, which led to the decrease of landscape fragmentation degree in
this area. |
