物元模型在庐山风景名胜区水环境质量评价中的应用

基于物元分析理论,将评价标准、评价因子及其特征值作为物元,对评价标准和水质指标实测值进行归一化处理后,得到模型的经典域、节域、权系数及关联度,从而构建庐山风景名胜区水环境质量评价的物元模型。结果表明,所评价水体优劣顺序芦林湖〉庐山会址〉电站大坝〉相思河〉剪刀峡〉如琴湖,其中芦林湖的最大关联度值为-0.016 7,可认定其基本符合Ⅲ类水质,而且关联度中仅次于最大值的是Ⅰ类（-0.216 4）,说明芦林湖水体转化为Ⅰ类水质的可能性较大。物元模型用于水质评价是合理可行的,且评价结果具有更高的分辨率,能全面分析判别待评价对象属于某一级别的程度,为水质评价提供了新的思路和方法。

Application of Matter Element Model in Water Environment Quality of Lushan Scenic Areas

Based on the matter element theory,the evaluation standards,factors and eigenvalues of water quality were selected as matter elements to do normalization process.The classical field,controlled field,weight coefficient and correlation degree from normalization process were applied to establish the matter element model in water quality assessment of Lushan scenic areas.The evaluated results showed that the water quality was Lulin lake> Lushan site> Power Dam> Acacia River> scissors Gap>Ruqin Lake.Lulin Lake had the largest correlation value of-0.016 7,which could be identified to water quality Ⅲ.And the second largest correlation value of-0.216 4 belonged to the water quality Ⅰ,which indicated that the possibility of Lulin Lake's water change to water qualityⅠwas greater.The matter element model was feasible for evaluating the water environment quality,and the evaluation results with higher resolution could analyze the extent how evaluation objects belonged to certain degree comprehensively.The study also expanded the ideas and methods of water environment quality assessment.
