A Maximum Sustainable Area Model for Harvesting Eichhornia Crassipe in Environmental Phytoremediation

Abstract:

The aim of this study was to investigate the use of a model to determine harvest area of Eichhornia crassipes in environmental phytoremediation. 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 maximum harvest area of Eichhornia crassipes from the logistic model and suggests that it is possible to implement environmental phytoremediation with the continuous harvest at the maximum sustainable area of Eichhornia crassipes.
