基于层次分析法的流域生态决策评价系统

探讨以西藏高原流域(涵盖金沙江、澜沧江、怒江和雅鲁藏布江流域)中典型区域为对象的流域生态决策评价系统实现方法.在制定流域生态环境质量评价指标体系的基础上,选用层次分析方法(AHP)建立了决策评价模型,并采用Java语言以组件的方式实现模型程序,设计并实现了流域生态决策评价系统.以流域中各种生态系统为例,系统进行了决策评...

Watershed ecological assessment system of decision-making based on AHP method

Taking typical regions in the Tibet plateau’s basin(Covering over Jinsha River,Lancang River,Nujiang River and the Yarlung Zangbo River basins,so called "Four River Basins") as the research object,this paper discusses the basin ecology decision-making evaluation system’s implementations.Based on the establishment of the basin ecological environment quality rating system’s indicator,It realizes the model procedure with software components of java language and by the analytic hierarchy method(AHP),establishes the decision-making evaluation model,studies and realizes the basin ecology decision-making evaluation system.Taking each kind of ecosystem in the basin as the example,the system’s scores prove that evaluation model’s result and the observed phenomenon of scientific expedition in the field are basically unanimous.This provides more accurate decision support for Tibet ecological environmental protection and the use of resources.In the basin,the coniferous forest and the scrub forest ecosystems have an immediate influence on the basin ecological environment quality,and the ecological environment quality of the rivers ecosystem is better than that of the lakes.so the prairie,meadow and dry land ecosystem’s management and protection should be strengthen.
