河流功能模糊综合评价模型研究与应用
Study and application of comprehensive fuzzy assessment model for river function
摘要
Abstract
Under comprehensive consideration of the openness,diversity and variability of river function,the function is divided into three classes,i.e.natural environment,eco-environment and social service,and then a comprehensive assessment model for river function is established through constructing index system and making assessment criteria with fuzzy theory.The hydrology station of Shijiao is selected as the control station,and representative indicators in 2010 are selected such as annual runoff change rate,river bed stability,ecologycal water security riparian vegetation coverage,species diversity,water quality control rate and water landscape status index,etc.The status of the river function of the North River System in Pearl River Basin is comprehensively assessed herein by taking the river system as the study case.The result shows that the status of the river function of the North River System is generally excellent,which indicates that considerations are given to both the improvement and protection and the inter-coordination among all the functions during the development and utilization of the North River,that is to say,while the natural function of the river is effectively brought into full play,its eco-environmental function and social service function are fully utilized;from which the assessment results are more closed to the actual conditions therein.关键词
