The water, which is the source of life, has a close relation with the growing of the human beings and the development of the city. the shore of river, ocean and lake is the cradle of humankind civilization. there is the original city in drainage areas of some rivers. the waterfront which has internal permanent attraction for humankind is the most sensitive area in urban environment and culture. however, at present days of the industrial civilization, with accelerating of urbanization and fastly enlarging of city size, some problems, such as the pollution of the environment, the lack of resource, the expanding of population, the traffic confusion, the unbalance of culture and the ecosphere crisis, have arised. these problems have badly influnced the development of urban waterfront. the whole world has know the importance of ecosphere crisis and the protection of environment but, how to treat the urban waterfront which is the typical environment of human living ? this article try to study the protection and utilization of resource, the development of economy and culture and the shaping of space landscape about the urban waterfront with the aspect of sustainablity development

    但是在工業文明日益發達的今天,隨著城市化進程的加快和城市規模的飛速擴大所帶來的環境污染、資源衰竭、人口膨脹、交通混亂、文化失衡和生態危機等問題,嚴重地影響了城市濱水區的發展。生態危機和環境保護已經引起了全球的重視,而城市濱水區作為人類聚居的一個典型環境,該何去何從呢?本文試圖以生態學理論為基礎,用可持續發展的觀點從生態持續、經濟持續和社會文化持續等幾個方面對城市濱水區的資源保護和利用、經濟、文化的發展和空間景觀的塑造進行研究。
  4. ( 5 ) the maximum water level risen by the enclose tideland cultivation around the reservoir is 0. 66m, the responding quality is 2000mvs, which heavily effect the environment around the reservoir. the reservoir " s water level is risen because cross section and flood canal become narrow, which caused by building dam, this makes groundwater unsmooth, drainage, even flow from a lower to a higher space and soil salinized

    66m ,且為2000m 』兒的常年洪水,對庫區周邊環境的影響較大,因打壩築堤縮小過水斷面和行洪通道造成水庫水位進一步抬升,致使庫區周邊灌區地下水排水不暢,乃至倒灌,型成士地鹽堿化。
  5. China is a large country with complex natural conditions. there are much inconsistency between the distributing of water resource and the requirement of industry, agriculture and life on time and space. pumping station is very important in the delivery, supply of water resource, especially the large - scale irrigation and drainage pumping station, which has very important contribution in fighting droughts and waterloggings

    我國地域遼闊,自然條件復雜,水資源在時間和空間上的分佈與工農業及生活的用水需求存在很多矛盾,泵站在水資源調配及工農業供水等方面起著十分重要的作用,尤其是泵站中較典型的大型排灌站,在抗旱排澇、減輕災害中發揮著巨大的功能。
  6. Thirdly, the mathematics model of forecasting low flow was established in fengcong and fenglin regions according to these factors influencing the amount of low flow in karst drainage ( the area of drainage, lithology, the type of landforms and its special assembly and forest ) the conception of low water resources carrying capacity was first put forward according to the changing law of low water resources in space and the situation of exploitation and utilization in karst drainage ( ie, under the condition of the virtuous ecological environment and the available technology, the explorable amount of water resources in certain areas is capacity and limitation which is able to coordinate the development of population, enviroment and economy during the period of low flow seasons ) and preliminarily analyzed its connotation, characteristic and established the index system of low flow in karst drainage

    三是根據影響喀斯特流域枯水徑流的下墊面因素(空間尺度、巖性、地貌類型、植被) ,分別對峰叢和峰林等喀斯特地區建立枯水徑流預測模型。根據喀斯特流域枯水資源的空間變化規律以及實際開發利用狀況,首次提出了枯水資源承載力的概念,即在枯水季節期間,保持良性的生態環境和現有的技術條件下,某一區域內可開採的水資源量對支持該地區人口、經濟與環境協調發展的能力和限度。並初步分析了枯水資源承載力的內涵、特性,從水資源的供需方面確立了喀斯特流域枯水資源承載力的指標體系。
  7. By the study, it proved gis to be an indispensability means in the hydrological study. it will exert important function on reasonably using real time space distributing information of hydrology and weather obtained by remote sensing technology, conveniently and rapidly updating hydrological subject database, setting up distributing course model that can reflect hydrologic phenomena and discipline, realizing hydrologic forecast real time, linking up the drainage area model, ground water model and surface water model and then establishing the gis of hydrology theme

    利用gis技術進行水文模擬,仍有許多難題需逐步解決,模擬精度也有待提高,但是地理信息系統在水文研究中的作用卻顯得日益突出,它將在合理利用水文遙感技術獲得的水文、氣象等實時空間分佈信息,方便快速地更新水文專題數據庫,建立反映水文現象客觀規律的分佈過程模型庫,實現實時水文預報,實現流域地面模型、地下水模型和地表水模型的定位銜接及最終建立水文專題地理信息系統等方面發揮重大作用。
  8. Because of modis predominant space and spectral differentiate rate, it ’ s has been broadly applied to various field, in the aspect of snow monitoring, modis has been successfully using a normalized difference snow index ( ndsi ) to provide global automated binary maps of snow cover. the ndsi is a spectral ratio that takes advantage of the spectral difference of snow in short - wave infrared and visible spectral bands, although it has higher precision, it can only discern one pixel to snow or other features, can not satisfy accurate drainage basin snow cover mapping and snow parameter extracting

    Modis數據因其優越的空間解析度、波譜解析度,已被廣泛的運用於各個領域,在積雪監測方面,已成功地運用歸一化差分雪蓋指數( ndsi )製作每天的全球雪蓋分布圖, ndsi是基於雪對可見光與近紅外波段的反射特性和反射差相對大小的一種測量方法,然而它只能將一個像元辨別為積雪或非積雪,滿足不了高精度應用要求。
  9. Therefor, in the light of theory and methods of karst hydrogeomorphology and the knowledge of transformation, balance and variation of matter and energy in karst drainage basin, we can examine stone forest within a specific scope of time and space, and reveal the mechanism and the development model of stone forest with the help of the principle of the mutual response processes among base - level, water flow and forms. just based on the understanding above, the paper, with a special reference to the lunan stone forest which is the best developed one in china, discusses the hydro - geomorphlogical structure of the bajiang river, geomorphological types and spacial distribution feature of the stone forest, and studies the erosion rate on the top of stone forest, soil erosion rate, sub - soil dissolution rate and their combined influences on the evolution of stone forest, furtherly brings forward and demostrates the " tri - level erosion " mechanism for the development of stone forest
