摘要
以甘肃省河西走廊疏勒河流域为例,对干旱内陆河流域生态环境预警分析问题进行了研究,提出以绿色当量面积作为该类流域主要生态环境预警指标,建立了基于人工神经网络的生态环境预警模型,给出了生态环境质量量化与预警分析方法。
Take the Gansu Hexi Corridor as an example, a study on the pre-warning method of ecological environment in the drought river basin is presented. Authors made a suggestion to set green area equivalent as the main pre-warning index of ecological environment in that basin. Based on the Nerve-Network, a pre-warning model of ecological environment is established,as well as the quantification of the quality of ecological environment and the pre-warning analysis method are introduced.Calculations show that, this method is feasible and the result is reasonable.
