摘　　要：通过实地调查和计算分析,水稻生长过程中稻田地表长期存水这一特性对地下水循环的影响是:增加了地下水的补给,减小了其排泄。以豫北沿黄河水稻种植区为例,在总结以往均衡计算成果和计算方法的基础上,定量计算和分析了水稻种植区对均衡计算的影响程度。结果表明在进行地下水资源均衡计算时如果考虑水稻种植的影响,资源量将比以往的计算结果增加8%左右,而且增加量均为可采资源量。Through field survey and calculation analysis, it is concluded that the influences of water ponding in paddy field during rice growing stages on groundwater cycle include groundwater recharging and discharge drainage. Taking the rice cropping area along the Yellow River in the northern Henan Province as an example, the extents of influence of rice cropping on the equilibrium calculation are calculated and analyzed quantitatively on the basis of the calculation results and methods before. The results show that the total quantity of water resources considering the influences is 8 % bigger than the calculation before; and the increased water resources are exploitable.
