摘要/Abstract

摘要： 利用定量和定性分析相结合的方法构建了东洞庭湖区域森林生态系统健康预警指标体系,通过样本训练、新样本模拟仿真,建立了BP神经网络预警模型,并利用该模型对东洞庭湖区域森林生态系统健康进行预警预测。结果表明:1)BP神经网络预警模型,拟合效果较好,用于森林生态健康预警是可行的;2)东洞庭湖区域森林生态系统整体处于蓝色和黄色警戒内,健康状况中等,需采取必要的健康经营方法。

关键词: BP神经网络, 森林生态系统健康, 预警, 东洞庭湖

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
