| 摘 要： | 基于江西省抚河流域内25个雨量站20年(1986～2005年)的雨量观测资料,采用SWAT模型划分子流域,结合标准差分级法,对抚河流域降雨进行时空变化分析,利用ArcGIS对子流域平均坡度和降雨进行栅格加权计算非点源污染风险值,并据此将流域划分非点源污染风险等级,为流域降雨与地形变化特征分析,以及流域非点源污染的影响作出了有益的探索,可供同行借鉴. |

| Abstract: | Besed on the observation data on rainfall from 25 stations within Fuhe watershed in Jiangxi province,for the time period from January 1st,1986 to December 31st,2005,the statistical analysis is carried out on their characteristics of the spatial and temporal variation of rainfall in Fuhe basin,Combined with the standard deviation gradational method and by using SWAT model to divide sub-basins.This paper utilized average slope and rainfall to calculate a weighted value of the risk of NPS pollution,by using the grid calculation method in the ArcGIS tools.And the basin was compartmentialized four grades of the risk of NPS pollution.It make a good explorations for analyzing the impacts of NPS pollution and basin rainfall and topographical variation.It can be referred for the relevent technicians. |
