摘　　要：根据从卫星遥感影像或全球定位系统获得的凤眼莲面积变化数据,对在开放水域中大面积放养凤眼莲面积变化的研究,建立了放养凤眼莲生长的Logistic动力学模型来估算凤眼莲面积。在太湖竺山湾凤眼莲放养试验表明:从2009年8月4日到10月15日,凤眼莲面积从54 250.34 m2增加到135 525.66 m2,建立的估计凤眼莲面积的Logistic模型的环境容量k s为2 697 210.03,面积增长率rs为0.012 4,对试验数据的拟合优度检验R 2为0.975 3,F检验为78.93,均方根误差RMSE为2 705.55,表明该模型准确模拟了凤眼莲生长的动力学特征。A logistic kinetic model,developed with the help of satellite remote sensing and GPS,is proposed for simulating the area growth of Eichhornia crassipes in the watershed of Taihu Lake.The results from the proposed model based on the field experiment of Eichhornia crassipes plantation in Zhushan Bay of Taihu Lake from Aug 4 to Oct 15 2009 shown that the total area of Eichhornia crassipes increases from 54250.34 m2 to 135525.66 m2.The area capacity and area growth rate of the proposed model are 2697210.03 and 0.0124 respectively.The goodness-of-fit test,-Tests and root mean square error（RMSE） of the proposed model are 0.9753,78.93 and 2705.55 respectively,which indicates that the proposed model simulates accurately the area growth characteristics of Eichhornia crassipes.
