摘 要: | 采用实地调查和实验分析,结合遥感和地理信息系统技术,研究南四湖湿地在1983-2006年浮游植物和水生维管束植物的种类、分布和生物量变化.结果表明,1983-2006年,南四湖湿地植被生物量整体呈下降趋势,反映了人类的围垦、养殖等活动造成湿地初级生产力的降低,并且这种影响由湖泊外围向湖心弱化,对外围湿地的影响最大.

Abstract: | The paper researched the Lake Nansi wetland phytoplankton species of aquatic vascular plants,distribution and biomass from 1983 to 2006.The methods were field investigation,laboratory analysis,remote sensing and geographic information system technology.The results showed that,wetland vegetation biomass continued to decrease in Lake Nansi from 1983 to 2006.Biomass of emergent plants decreased the fastest,followed by floating-leaved plants and submerged plants.The result reflects the human reclamation,aquaculture and other activities caused reduction in primary productivity.This effect decreased gradually from the periphery to the center of the Lake. |
