Towards the research on two flood water of yuhe river in datong city during 2004, by measuring and comparing their discharge, sediment concentration 、 nutrient include organic, phosphorus, potassium, azote, the result shows that the nutrient content of the sediment is greatly larger than that of supernatant fluid
摘要以2004年大同市御河乾渠兩場洪水為研究對象,對其流量、含沙量、養分(包括有機質,氮,磷,鉀)做了測定和比較,研究結果表明:洪水中下層泥沙中的養分含量遠大於上清液中的養分含量;洪水中整體養分含量隨著含沙量的增大而增大,並且養分含量和含沙量呈近似線性關系。Abstract : digital basinis made from digital elevation model considering spatial variability within a catchment. on the basis of digital basin, the digital approach to describing hydrological processes within a catchment is investigated. digital hydrological model is regarded as a modern physically - based modeling technique that includes a large amount of information. the case study on the shiguanhe catchment in the huaihe river basin, intensified observation field of gewex asian monsoon experiment project, has shown that the digital mode lperforms very well not only in simulating runoff processes at any specific site, but also in simulating spatial distribution and temporal variation of hydrological elements and state variable ( especially soil moisture ), if compared with traditional hydrological models. that provides solid foundation for full use of now available observation in formation and in - depth mining of hydrological data
文摘:考慮流域下墊面空間變異性,基於數字高程模型構建了數字流域,並在此基礎上對描述流域水文物理過程的數字方法進行了探討.文章認為,數字水文模型是一種有物理基礎的包含大容量信息的現代模擬技術.史灌河流域實例研究表明,數字水文模型可以十分方便地輸出水文要素和狀態變量的空間分佈與時間序列,這對充分利用現有觀測信息進行水文信息的深層挖掘創造了條件Vulnerability of karst aquifers in houzhai river basin and its relations with landuse change
后寨河流域巖溶含水層脆弱性及其對土地利用方式的響應( 4 ) at the height of the summer, the surface and bottom water of the creeks differed in n and p loadings. nh4 +, soluble p and total reactive p in the bottom water were higher than those in the surface ; while no3 - and no2 - in the surface were higher than those in the bottom. such water - quality stratification inevitably resulted from the enhancement of phytoplankton in the surface water and intensified release of nh4 + and p from the sediments
( 4 )在盛夏高溫季節,水流滯緩的小河流表層水和底層水的氮磷指標存在明顯分異:底層水nh _ 4 ~ + ,水溶態磷和總反應態磷( trp )含量高於表層水;而表層水no _ 3 ~ -和no _ 2 ~ -含量高於底層水;表層水的ph和do高於底層水。With the increase of temperature and biomass, nh4 + and no3 - in the surface water were largely consumed and decreased as a result ; while organic n and particle p increased as the enhancement of suspending biological particles. no2 - in the surface water increased with temperature as nitrifying bacteria became active
隨著氣溫升高和河流表層生物量的增大,表層水nh _ 4 ~ + 、 no _ 3 ~ -因大量消耗而降低;有機氮和顆粒態磷含量因生物顆粒的增加而加大; no _ 2 ~ -也會因硝化細菌活動的加劇而增加。Changing of the riverbed conductance provides high change in river gaining rate compared to change in river losing rate. this difference can be attributed to aquifer anisotropy, river penetration, hydraulic balance between groundwater head and river stage
其中河床沉積物滲透性的改變引發的河流得水率變化明顯大於河流失水率的變化,分析其原因為含水層的各向異性、河流的滲漏、河水與地下水的水力均衡。This research is proposed to formulate a new approach that used for the first time for quantitative groundwater vulnerability assessment ( gva ) through gis programs, based on visual modflow as comparative technique ; evaluate river - aquifer interaction and assess the effect of riverbed conductance on river leakage using the natural field conditions instead of hypothetical models that used in the pervious researches
本研究使用了一種新的地下水脆弱性評價方法? ?基於gis與可視化modflow地下水流數值模擬結果上的地下水脆弱性評價,並用數值模擬結果作為其對比技術;評價了河流與附近含水層的相互作用。The river package of visual modflow code was used to understand the interaction between songhuajiang river and the nearby aquifer and the effect of riverbed conductance on river leakage. induced infiltration, reduced baseflow, river losing and river gaining are the main factors used to demonstrate these phenomena
用modflow的河流程序包對松花江與附近含水層以及河床沉積物滲透性的互聯系進行分析,並用誘發入滲、基流減少、河流失水和河流得水等4個主要因子來證明。分享友人
