滹沱河流域平原区人类活动强度的定量评价

人类活动强度的定量评价是分析人类活动对浅层地下水系统干扰的基础,也是有意识控制人类行为、涵养地下水的依据。文中以滹沱河流域平原区为研究区,针对人类活动对浅层地下水影响的特点,筛选人口、耕地面积、开采井数量、粮食产量、河道过水量和水渠引水量作为衡量人类活动强度的指标,采用指标加权和专家打分相结合的方法,对滹沱河流域平原区不同区位、不同年代的人类活动进行定量分析,得到如下结论:上游人类活动强度最大,为0.79,中游和下游地区较小,分别为0.38和0.45;在20世纪70、80、90年代和21世纪,研究区人类活动强度分别为0.35、0.46、0.67和0.71,也就是人类活动表现为不断发展、积累和增强的过程。

Quantintative assessment of human activity intensity in Hutuohe catchment

Quantitative assessment of human activity intensity was a basis for analyzing of effect of human activity on hydrological cycle evolution,and the basis of controlling consciously of human behavior,self-restraint of groundwater.This research chose Hutuohe catchment plain as investigation area,and the population,cultivated land area,total extraction well,foodstuff yield,instream flow and channel water division were selected as indexes of measuring human activity aiming at the characteristics of human disturbing the fellow groundwater.The method of weighted index was applied to quantitatively express human activities,including in different era and regions.The conclusion was: the human activities intersity in the upriver was 0.79,the most;that in the lower reaches was 0.38,the least;that in the catchment area was 0.48,the middle.In 70s,80s,90s of 20 century and 21,the human activities intensity were 0.35,0.46,0.67 and 0.71 respectively,showing the human activities behaved the course of developing constantly,accumulating and builduping.
