河北南部平原地下水位变化趋势及其对农业生态环境的影响

简要介绍了河北南部平原石家庄市、衡水市与沧州市地下水位平均埋深、影响与对策,建立了石家庄市地下水位平均埋深与粮食总产、降水量的回归关系。较详细地分析了地下水水环境问题及其对策,这些水环境问题有:地下水超采、地下水降落漏斗与地面沉降、地下水污染(农药、化肥污染、饮水型氟中毒)等,建立了石家庄漏斗、冀枣衡漏斗和沧州漏斗中心水位埋深与降水比率、地下水累积开采量的回归关系。

Changing Tendency of Groundwater Level and Its Effects on Agro-Ecological Environment in the South of Hebei Plain

Average depth, effect and countermeasures of groundwater level in Shijiazhuang City, Hengshui City and Cangzhou City of the South Hebei Plain are briefly described in this paper, in which regression relationship among average groundwater level depth and total yields of grain and precipitation in Shijiazhuang City are established. Aquatic environmental issues of groundwater and their countermeasures were minutely evaluated, including over-use of groundwater, drawdown funnel of groundwater and ground descension, groundwater pollution (pesticide or chemical fertilizer pollution, fluorine poisoning in drinking water) and so on, in which the regression relationships among the centre water table depth of Shijiazhuang Funnel, or Jizaoheng Funnel or Cangzhou Funnel and the precipitation rate, the accumulative exploitation of groundwater were set up, respectively.
