Early Warning of Forest Ecosystem Health Based on BP Neural Network in East Dongting Lake Area

Abstract

Abstract: Based on the combination of qualitative analysis and quantitative analysis,early warning of forest health indicator system was established,then the early health warning model of forest ecosystem was established by sample training and new sample simulation.The results showed that:(1)It was feasible to do early warning study on forest ecosystem health by using BP neural network model because of its high precision of simulation result;(2)The forest ecosystem of East Dongting Lake Area,which was on the whole in the range of the yellow and blue alert, was in medium health and needed the necessary health management methods.

Key words: BP neural network, forest ecosystem health, early warning, East Dongting Lake
