| 摘 要： | 以Landsat TM/OLI卫星影像为数据源,采用面向对象的分类方法对1990、2000、2010和2015年4个时相的海南岛海水池塘养殖信息进行提取,利用景观格局指数和质心迁移模型研究海水池塘养殖的时空变化特征及其对近岸生态环境的影响。结果表明,1990—2015年海南岛海水池塘养殖面积持续增长且区域差异明显;空间上表现为从西南向东北的迁移;养殖区景观格局趋于破碎化;池塘养殖的扩张侵占了红树林等自然湿地,严重破坏了沿岸生态环境。研究表明海南岛的海水养殖业需要合理的规划布局和科学的改造升级。

| Abstract: | The object-oriented classification method was utilized to interpret 4 time-series Landsat data of 1990,2000,2010 and 2015 to identify the aquaculture ponds in coastal area of Hainan Island. Based on the landscape indexes and centroid migrate model,the temporal and spatial characteristics of aquaculture ponds and its impact on the coastal ecological environment were explored. The results showed that the area of aquaculture ponds of Hainan Island continued to grow from 1990 to 2015 and the regional differences were obvious. The distribution position of aquaculture area moved to the northeast of Hainan Island and the landscape indexes showed that the landscape pattern of the aquaculture area tended to be fragmention. The expansion of aquaculture ponds invaded natural wetlands such as mangroves, causing damage to the coastal ecological environment. Therefore, reasonable planning and scientific upgrading are needed for the sustainable development of aquaculture. |
