摘要
使用 GIS手段对九段沙的卫星资料和实地调查数据进行分析 ,研究了九段沙的自然植被及人工植被分布状况 .绘制了九段沙植被分布图 ,对九段沙上的植被进行了地上、地下部分的生物量测定 ,确定了生物量高峰期 .这对了解该岛湿地生态系统。
With the data from satellite sensor and field investigation analyzed by means of GIS, the distribution characteristics of natural and artifial vegetation in Jiuduansha wetland were reported. The vegetation distribution map of Jiuduansha was drawn. The upground and underground biomass of vegetation were determined and the period of maximum biomass was recognised in Jiuduansha island. All of these investigation results give basic information to understand the wetland ecosystem and its enviroment factors ,and to research the characteristics and laws of community succession.
