【摘要】：河流水生態(tài)環(huán)境問(wèn)題越來(lái)越引起人們的高度重視,馬頰河是海河流域的一條重要河流,了解馬頰河的健康狀況,能為其進(jìn)一步的良性運(yùn)行或綜合治理提供技術(shù)參考。本文主要研究?jī)?nèi)容及結(jié)果如下：1、查閱了國(guó)內(nèi)外河流健康評(píng)價(jià)相關(guān)研究文獻(xiàn),了解了河流健康評(píng)價(jià)的研究現(xiàn)狀,與研究對(duì)象馬頰河進(jìn)行對(duì)比分析,得出評(píng)價(jià)馬頰河河流健康評(píng)價(jià)的技術(shù)路線和評(píng)價(jià)指標(biāo)體系。2、根據(jù)國(guó)內(nèi)外的河流健康評(píng)價(jià)體系及其有關(guān)內(nèi)容,構(gòu)建適合馬頰河河流健康評(píng)價(jià)的指標(biāo)體系,應(yīng)用了專家咨詢法和層次分析法建立了評(píng)價(jià)指標(biāo)體系。充分考慮流域地區(qū)的差異性和動(dòng)態(tài)性,綜合國(guó)內(nèi)外已有的河流健康評(píng)價(jià)理論體系的研究成果的相關(guān)參數(shù)以及海河流域在山東段的馬頰河的實(shí)際情況,確定了河流健康的評(píng)價(jià)等級(jí)標(biāo)準(zhǔn)。3、借鑒了前人的研究成果及馬頰河的具體資料,構(gòu)建了多層次多目標(biāo)的評(píng)價(jià)馬頰河河流健康的模型。4、根據(jù)實(shí)測(cè)數(shù)據(jù)分析了馬頰河典型斷面的水質(zhì)時(shí)空變化規(guī)律,主要包括不同斷面同一元素的時(shí)空變化及同一斷面不同元素的時(shí)空變化特點(diǎn)。5、采取投影尋蹤模型進(jìn)行計(jì)算馬頰河河流健康評(píng)價(jià)的目標(biāo)函數(shù),利用遺傳算法尋找最優(yōu)解,找出最優(yōu)方向,進(jìn)而計(jì)算出不同斷面中各個(gè)指標(biāo)對(duì)河流影響程度,最終計(jì)算出各個(gè)斷面的水質(zhì)情況。采用投影尋蹤模型和層次分析法的結(jié)合進(jìn)行計(jì)算,得到所選典型斷面的健康情況結(jié)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.
