【摘要】：河流水生态环境问题越来越引起人们的高度重视,马颊河是海河流域的一条重要河流,了解马颊河的健康状况,能为其进一步的良性运行或综合治理提供技术参考。本文主要研究内容及结果如下：1、查阅了国内外河流健康评价相关研究文献,了解了河流健康评价的研究现状,与研究对象马颊河进行对比分析,得出评价马颊河河流健康评价的技术路线和评价指标体系。2、根据国内外的河流健康评价体系及其有关内容,构建适合马颊河河流健康评价的指标体系,应用了专家咨询法和层次分析法建立了评价指标体系。充分考虑流域地区的差异性和动态性,综合国内外已有的河流健康评价理论体系的研究成果的相关参数以及海河流域在山东段的马颊河的实际情况,确定了河流健康的评价等级标准。3、借鉴了前人的研究成果及马颊河的具体资料,构建了多层次多目标的评价马颊河河流健康的模型。4、根据实测数据分析了马颊河典型断面的水质时空变化规律,主要包括不同断面同一元素的时空变化及同一断面不同元素的时空变化特点。5、采取投影寻踪模型进行计算马颊河河流健康评价的目标函数,利用遗传算法寻找最优解,找出最优方向,进而计算出不同断面中各个指标对河流影响程度,最终计算出各个断面的水质情况。采用投影寻踪模型和层次分析法的结合进行计算,得到所选典型断面的健康情况结果。
[Abstract]:The problem of the ecological environment of the river is more and more important to people, and the Mabuci River is an important river in the Haihe River basin, and the health status of the horse's cheek is known, and the technical reference can be provided for the further benign operation or comprehensive treatment of the river. The main contents and results of this paper are as follows: 1. Review the relevant research literature of the river health evaluation at home and abroad, understand the research status of the river health evaluation, and make a comparative analysis with the study subject Ma's buccal river. The technical route and the evaluation index system of the evaluation of the health of the river are obtained. According to the domestic and foreign river health evaluation system and its related contents, the index system for the health evaluation of the river is constructed. The evaluation index system is established by the expert consultation method and the analytic hierarchy process. Taking full consideration of the difference and dynamics of the river basin area, the relevant parameters of the research results of the existing theoretical system of the river health evaluation at home and abroad, as well as the actual situation of the Mabuci River in the Shandong section of the Haihe river basin, are considered, and the evaluation grade of the river health is determined. Based on the previous research results and the specific data of the horse's cheek, a multi-objective model for evaluating the river health of the Malbuci River was constructed. 4. The temporal and spatial variation of the water quality of the typical cross section of the Mabuci River was analyzed according to the measured data. the time-space variation of the same element of different sections and the time-space variation characteristics of different elements of the same section are mainly included. 5, a projection pursuit model is adopted to calculate the objective function of the health evaluation of the river and a river, and the optimal solution is searched by using the genetic algorithm to find the optimal direction, and then the influence degree of each index in different sections on the river is calculated, and the water quality condition of each section is finally calculated. The combination of the projection pursuit model and the analytic hierarchy process is used to calculate the health condition of the selected typical cross section.
