(1 ) at first, the conception of egis is put forward . and some basic techniques of it are discussed, including the integration of the applied numerical model with gis, the research of creating dem ( digital elevation model ) and the application of dem in ece 本文的主要研究內(nèi)容是:(1)提出建立工程地理信息系統(tǒng)egis,并進行一些基本方法的探討,包括應(yīng)用模型與gis集成模式的討論,數(shù)字地面模型生成的方法比較和應(yīng)用。
At present, many fields remain to further research, especially the profound combination of gis technique with ece ( estuarine and coastal engineering ), which should be developed for the purposes as follows : ( 1 ) to serve the huge comprehensive work in changeable natural conditions and difficult construction conditions which takes a long period and covers a large region, e . g . the regulation work of deepwater channel in the yre ( yangtze river estuary ) ( 2 ) to combine the gis with applied numerical model ( 3 ) to study the hydrodynamic processes and characteristics of waves, tidal currents and sediment transport, as well as the affection carried by the regulation work in an estuary ( 4 ) to monitor and to analyze ees ( evolution of erosion and sedimentation ) and the variation of riverbed ( 5 ) to play a role of dynamic supervising of a engineering project 目前尚有許多有待進一步研究的領(lǐng)域,尤其是以服務(wù)于長江口深水航道治理這樣規(guī)模大、周期長、影響區(qū)域廣、自然條件復(fù)雜、施工情況多變的國家重點工程為目的,將gis與專業(yè)應(yīng)用數(shù)學(xué)模型結(jié)合,對河口海岸波浪、潮流、泥沙運動的動力機制,以及整治工程建筑物對其影響的研究,對入海航道沖淤和河勢演變的監(jiān)測分析,對施工進展和工程效果實現(xiàn)“動態(tài)”監(jiān)控和管理,尚缺乏同gis技術(shù)的深入有效結(jié)合。
