灌溉入渗补给系数
coefficient of irrigation recharge into ground water
guan’gai rushen buji xishu灌溉入渗补给系数(eoeffieient of irriga-tion reeharge into ground water)灌溉水补给地下水的数量指标，是灌溉入渗补给地下水的量与灌溉水量之比。影响因素主要有灌溉定额，土壤含水量、土壤质地、地下水埋深、植被情况和气候条件等。 灌溉水入渗，只有在土壤含水量超过田间持水量时，多余的水才能补给地下水。一般在相同的条件下，灌溉定额小、土壤质地粘重与植被差时，灌溉入渗补给系数小(如果灌溉定额很小，可能无入渗补给);反之则大。田间的地下水埋深大(即非饱和带上壤的厚度较大)，故灌溉入渗补给系数小;反之亦然。当引外区的河水或井水时，由灌溉入渗补给系数算得补给地下水量，作为本区的地下水补给量。引河水灌溉，一般灌水定额较大，灌溉入渗补给系数大;引井水灌溉，灌水定额较小，此系数亦小。(金光炎)
