中文摘要 | AnnAGNPS(Annualized Agricultural Non—point Pollutant Loading Model)是一个基于连续事件的分布式流域模型,与地理信息系统软件ArcView3.2a紧密集成,快速提取地面数据,不仅可以模拟非点源污染过程,还可以模拟多尺度流域的水、沙、输移与转化等水文过程。在介绍了该模型的原理、结构、功能及其研究进展后,探讨了模型存在的主要问题和应用前景。 |
英文摘要 | Abstract:Concerns over non-point source pollution(NPS)has been widely raised in many countries.Due to the NPS complexity an d expensive nature of laboratory and field observations,NPS management necessitate the development and use of the water quality models such as AnnAGNPS(Annualized Agricultural Non-point Pollutant Load— ing mode1).AnnAGNPS is a continuous simulation,daily time step and watershed-scMe model developed based on the single—event model AGNPS.It is the result of a joint efort of USDA Natural Resources Conservation Service and Agricultural Research Service to develop a system of models to predict non·-point source pollutant loading within ag·- ricultural watersheds.The model includes significan tly advan ced foamres such as pesticides,source accounting,setfling of sediments due to in-stream impoundments,and the Revised Universal Soil Lo ss Equ ation in addition to many of the important features in the original AGNPS.Th e model divides the watershed into homogenous the cels (1and areas)with respect to soil type,land use,and land management.,which are then integrated together by simulated rivers and streams,routing the runof an d polutan ts from each area downstream .AnnAGNPS simulates surface water,sediment,nutrients and pesticides leaving the cels and their transport through the watershed.Th e hydrology of the model is based on simple water balance approach.Runof qu antities are based on runof Curve num— bers while sediment is determined by using the Revised Universal Soil Loss Equation(RUSLE).Special components are included to handle concentrated sources of nutrients(feedlots and point sources),concentrated sediment sources(gulies),and added water(irrigation).AnnAGNPS with the integration of GIS ArcView 3.2 a facilitates development of input data files an d for analysis of output data.Output is expressed on all event basis for selected stream reaches and as source accounting(contribution to outlet)from land or reach components over the simulation period.It is an efective tool for evaluating the hydrologic and water qu ality responses of a watershed to alternative management practices. In addition,cropping systems,fertilizer application rates,water an d dissolved nutrients from point sources,sediment with a~ached chemicMs from gu llies,soluble nutrient contributions from feedlots,and the effect of terraced fields can also be modeled.Th is paper mainly introduces the issues of the hydrological theory , the structure and functions of AnnAGNPS mode1.Th e research progress at home an d abroad and the existing problems of the AnnAGNPS po lutant transport model are also analyzed.Finaly the prospect of the model in China is evaluated |
