An Area Growth Model of Eichhornia Crassipes with Application to Lake Ecosystem Restoration

Abstract:

The aim of this study was to investigate the use of a model to determine growth properties of Eichhornia crassipes in lake ecosystem restoration, in particular Eichhornia crassipes area. A logistic model was constructed to eatimate the area of Eichhornia crassipes and tested in Eichhornia crassipes samples. The area of Eichhornia crassipes was measured nine times in experiment period using GPS and satellite remote sensing images. The measurements were shown to lead to a determination of the parameters of accurate logistic model with an overall Goodness of Fit Index of 0.9753. This indicates that there is a possibility of obtaining accurate Eichhornia crassipes area from the logistic model and suggests that it is possible to implement lake ecosystem restoration with harvesting Eichhornia crassipes to remove the nutrient in lake.
