摘 要: 通过对20世纪80年代至今的4个不同时相的Landsat-5卫星遥感数据的解译,得到福田红树林保护区4个年份的土地分类及利用状况,对比研究各时期的湿地动态变化表明:在1986—2008年,该区红树林面积增加49.70hm2,动态度达到4.24;滩涂面积减少了42.22hm2,动态度为-1.62;陆地植被、建筑裸地面积分别增加25.82hm2,11.46hm2,动态度达到了9.23,10.67。针对保护区动态变化,提出了保护、修复与发展保护区的建议。 The four years' land classification and use status of Futian is gained through the analysis of the Landsat-5 satellite remote sensing data of 80's of the last century to 2008.It is indicated by comparion of dynamic changes over each period that the mangrove area increases by 49.70hm2,dynamic degree reaches 4.24;the beach area decreases by 42.22hm2,dynamic degree reaches-1.62,the land vegetation and building and bare land increases by 25.82hm2 and 11.46hm2 respectively and dynamic degree reaches 9.23,10.67.The suggestion on scientific and reasonable protection,restoration and development of protected areas is put forward for dynamic changes in the protected areas.
