【摘要】:隨著秦皇島市市政府對石河資源開發(fā)力度的逐漸增大,以及對石河“城市生態(tài)景觀名片”的重新定位,科學(xué)、先進(jìn)的管理技術(shù)勢必會很快地運(yùn)用到石河的水環(huán)境信息管理工作中。為了提高石河水環(huán)境信息的管理水平和決策依據(jù),本論文主要構(gòu)建了基于地理信息系統(tǒng)(Geographic Information System, GIS)的水環(huán)境管理系統(tǒng)。在對秦皇島市石河水環(huán)境現(xiàn)狀進(jìn)行分析和總結(jié)后,收集和提取了石河流域相關(guān)的水資源信息,建立了包括河流地理形態(tài)、周邊環(huán)境、水質(zhì)監(jiān)測等數(shù)據(jù)在內(nèi)的石河水環(huán)境信息空間數(shù)據(jù)庫,然后采用C樣為程序設(shè)計(jì)語言,Access為后臺數(shù)據(jù)庫,通過嵌入式GIS組件庫-ArcGIS Engine,并結(jié)合水質(zhì)預(yù)測模型,構(gòu)建了基于GIS的水環(huán)境管理系統(tǒng)。該系統(tǒng)總體構(gòu)架分為系統(tǒng)管理、信息查詢、數(shù)據(jù)管理、預(yù)測模擬四大功能模塊,各模塊間相互獨(dú)立、互相調(diào)動,在每一個(gè)模塊的功能上又進(jìn)行了詳細(xì)的劃分。論文重點(diǎn)對預(yù)測模擬模塊進(jìn)行了研究,針對石河的水力、水質(zhì)特征以及污染物的排放情況,選擇二維穩(wěn)態(tài)預(yù)測模型對石河水體中COD和NH3-N的濃度分布進(jìn)行模擬,并驗(yàn)證了所選取的水質(zhì)參數(shù),預(yù)測結(jié)果和模擬值擬合度較高(大部分模擬誤差在30%以下)。然后通過GIS組件將COD和NH13-N的濃度分布在河流層面上通過漸變色的形式直觀展示出來,為水環(huán)境相關(guān)部門提供決策依據(jù)。同時(shí),選取瞬時(shí)點(diǎn)源二維模型對石河突發(fā)污染狀況進(jìn)行預(yù)報(bào)預(yù)警,預(yù)測突發(fā)性污染對石河的影響程度和范圍。本系統(tǒng)操作界面簡便、友好,基本實(shí)現(xiàn)了空間可視化技術(shù)、數(shù)據(jù)庫技術(shù)和水質(zhì)預(yù)測模型的有機(jī)結(jié)合,提高了石河水環(huán)境管理管理效率,同時(shí)對石河后續(xù)的相關(guān)研究提供了參考。
[Abstract]:Along with the Qinhuangdao Municipal Government's gradual increase in the intensity of exploitation of the Shihe River resources, as well as the re-orientation of the Shihe's "card of urban ecological landscape",Advanced management technology will soon be applied to the water environment information management of Shihe River.In order to improve the management level and decision-making basis of water environment information in Shihe River, a water environment management system based on GIS (Geographic Information system) is constructed in this paper.After analyzing and summarizing the present situation of the water environment of Shihe River in Qinhuangdao City, we collected and extracted the relevant water resources information of the Shihe River Basin, and established the water resources information, including the geographical form of the river, the surrounding environment,The water environment information spatial database of Shihe River, including water quality monitoring data, and C sample programming language access is used as backstage database, through embedded GIS component library -Arc GIS engineer, and combined with water quality prediction model.The water environment management system based on GIS is constructed.The overall framework of the system is divided into four functional modules: system management, information query, data management, prediction and simulation. Each module is independent and mobilized, and the function of each module is divided in detail.This paper focuses on the prediction simulation module. According to the hydraulic, water quality characteristics and pollutant discharge of Shihe River, a two-dimensional steady-state prediction model is selected to simulate the concentration distribution of COD and NH3-N in the water body of Shihe River.The results show that the predicted results and the simulated values fit well (most of the simulation errors are less than 30%).Then the concentration distribution of COD and NH13-N on the river level is displayed directly by GIS component, which can provide the decision basis for the relevant departments of water environment.At the same time, the instantaneous point source two-dimensional model is selected to predict the sudden pollution situation of Shihe River, and the influence degree and range of sudden pollution on Shihe River are predicted.The operating interface of the system is simple and friendly, which basically realizes the combination of spatial visualization technology, database technology and water quality prediction model, improves the efficiency of water environment management and management of Shihe River, and provides a reference for the subsequent research on Shihe River.
