【摘要】：當(dāng)前鄱陽湖流域環(huán)境的污染和生態(tài)環(huán)境惡化等現(xiàn)象已經(jīng)嚴(yán)重威脅了人類的生產(chǎn)生活，為了改善當(dāng)前情況，開展了鄱陽湖流域生態(tài)的調(diào)度研究工作，論文以鄱陽湖流域?yàn)檠芯繀^(qū)域，應(yīng)用鄱陽湖流域基礎(chǔ)數(shù)據(jù)、地理數(shù)據(jù)、遙感影像、生態(tài)數(shù)據(jù)以及監(jiān)測數(shù)據(jù)等數(shù)據(jù)源，結(jié)合目前應(yīng)用廣泛的3S、WebGIS等先進(jìn)技術(shù)，建立了鄱陽湖流域生態(tài)數(shù)據(jù)庫和信息共享平臺，并進(jìn)行應(yīng)用分析，在鄱陽湖流域生態(tài)數(shù)據(jù)庫的建設(shè)方面，主要從設(shè)計(jì)原則、空間數(shù)據(jù)結(jié)構(gòu)設(shè)計(jì)、屬性數(shù)據(jù)庫的設(shè)計(jì)和空間數(shù)據(jù)的組織與管理等進(jìn)行探討和實(shí)現(xiàn)，在信息共享平臺的開發(fā)方面，主要從共享平臺的需求分析出發(fā)，重點(diǎn)討論其總體設(shè)計(jì)和功能設(shè)計(jì)，，實(shí)現(xiàn)鄱陽湖生態(tài)數(shù)據(jù)庫智能高效的一體化管理，具備實(shí)時(shí)更新、維護(hù)、查詢、存儲、檢索、分析修改地理數(shù)據(jù)的功能。結(jié)合現(xiàn)代遙感技術(shù)，構(gòu)建了鄱陽湖生態(tài)數(shù)據(jù)的生態(tài)指標(biāo)體系，解決了鄱陽湖生態(tài)環(huán)境的評價(jià)等問題。系統(tǒng)從真正意義上實(shí)現(xiàn)了生態(tài)數(shù)據(jù)的網(wǎng)絡(luò)共享，能實(shí)時(shí)查詢鄱陽湖的生態(tài)成果數(shù)據(jù)，解決了各部門、單位之間數(shù)據(jù)冗余、重復(fù)采集、資源嚴(yán)重浪費(fèi)問題，提升了整個(gè)信息系統(tǒng)的服務(wù)價(jià)值，加速了我國數(shù)字流域的進(jìn)程，為保護(hù)鄱陽湖的“一湖清水”提供科學(xué)的依據(jù)。
[Abstract]:At present, the pollution of the environment and the deterioration of the ecological environment in the Poyang Lake basin have seriously threatened the production and life of human beings. In order to improve the current situation, the study of ecological regulation in the Poyang Lake basin has been carried out.Taking Poyang Lake Basin as the research area, the paper applies the data sources such as basic data, geographical data, remote sensing image, ecological data and monitoring data of Poyang Lake Basin, and combines with the advanced technologies such as 3s Web GIS, which are widely used at present.The ecological database and information sharing platform of Poyang Lake basin are established and analyzed. In the construction of ecological database of Poyang Lake basin, the design principles and spatial data structure design are discussed.The design of attribute database and the organization and management of spatial data are discussed and realized. In the development of information sharing platform, the general design and function design are discussed mainly from the requirement analysis of sharing platform.Poyang Lake ecological database intelligent and efficient integrated management, with real-time update, maintenance, query, storage, retrieval, analysis and modification of geographical data functions.Combined with modern remote sensing technology, the ecological index system of Poyang Lake ecological data was constructed, and the evaluation of Poyang Lake ecological environment was solved.The system realizes the network sharing of ecological data in real sense, can query the ecological achievement data of Poyang Lake in real time, solves the problem of data redundancy, repeated collection and serious waste of resources among various departments and units.It enhances the service value of the whole information system, accelerates the process of digital watershed in our country, and provides scientific basis for protecting Poyang Lake's "one lake clear water".
