摘要
过去水资源总量定义为流域产水量,即由降水量减去包气带蒸散发量、水体蒸发和植物截流量。本文认为应将包气带蒸散发量分为包气带地表蒸散发量和植株蒸腾两部分,后者应包含在水资源的总量中。
This paper presented a new thinking of water resources aggregate quantity,which divided evapotranspiration in aeration zone and plant transpiration,and the latter should be included in water resources aggregate quantity.
