| 摘 要： | 以河北省北沟林场的森林生态系统健康预警为主线,首先通过定量分析和定性分析相结合的方法对森林健康预警指标进行筛选,确定了预警的指标体系;进而基于BP神经网络的基本原理建立了森林生态系统健康预警模型,对森林生态系统健康状况进行了预警。结果表明,北沟林场森林生态系统整体处于绿色和蓝色警戒内,健康状况良好。

| Abstract: | Taking forest ecosystem health early warning in the North Ditch,Hebei Province as the main line,early warning indicators of forest health were firstly filtered by the method of quantitative analysis,then early warning indicator system was identified.Next,early health warning model of forest ecosystem based on the basic principles of BP neural network was established,and then it was used to make early warning on the health of forest ecosystems.The results showed that North Ditch forest ecosystem was in good ... |
