简介：基于资源卫星介绍的遥感数据的解释，这份报纸说事实在Donghai岛的陆地使用区域，位于Zhanjiang的南方，广东省，因为象陆地开垦那样的人的活动，从1986～2010在25年里由576.71hm2膨胀了；同时，在土地的类型的大变化在岛上盖住发生了。在陆地使用的明确的变化在它的生态系统服务价值导致显著转变。因此，由在这使用Costanza方法，quantificationally在它的生态系统分析变化的纸在这个岛上满足；Costanza方法是每统一岛的区域显示出服务价值的一种计算技术。它从1986～2010被发现那，特别在最近的年里，由于在僵化，钢和港口工业，栽培土地的区域，树林，草地和沙漠的快速的发展在不同的度减少了，当时为住处的陆地，工业和交通建设和水和沼泽地的区域增加了。因而，与RMB547.57漠?潦的数字相比？
