基于模糊权物元理论的地下水资源承载力评价分析
|
摘要
针对传统地下水资源承载力评价方法存在地下水资源承载力等级划分不合理、评价分析结果准确率低的问题,提出基于模糊权物元理论的地下水资源承载力评价分析方法,依据模糊权物元理论构建模糊权物元模型,选取8个地下水资源承载力评价指标对不同地区的地下水资源承载力等级进行划分,采用熵值法确定不同承载力评价指标的权重,通过欧氏贴近度衡量评价样本和标准样本间贴近度的大小,使用不同评价指标对地下水资源承载力的影响进行划分,实现地下水资源承载力的准确评价。通过实验可知,所提方法下的所有承载力评价指标的准确率均高于90%,说明所提方法对地下水资源承载力等级划分合理、评价结果准确率高。
Aiming at the problems of unreasonable classification and low accuracy of evaluation and analysis result of groundwater resources carrying capacity in the conventional methods for evaluation and analysis of groundwater resources carrying capacity,a fuzzy weight matter element theory-based method for evaluation and analysis of groundwater resources carrying capacity is proposed herein,for which the fuzzy weight matter element model is established with the fuzzy weight matter element theory,and then 8 indexes for evaluating groundwater resources carrying capacity are selected for classifying the grades of groundwater resources carrying capacities of various regions,while the weights of the evaluation indexes for various carrying capacities are determined with entropy method,the approach degree between both the evaluation sample and the standard sample is judged through Euclid approach degree and the influences of groundwater carrying capacity are classified with various evaluation indexes,thus the accurate evaluation of groundwater resources is realized. It is known through the relevant experiment that the rates of the accuracy of all the carrying capacity evaluation indexes got from the method proposed herein are higher than 90%,which indicates that the classification of groundwater resources carrying capacity made by the proposed method is reasonable,while the accuracy of the evaluation result is high as well.
