摘  要：
实行最严格水资源管理制度的关键在于耗水管理,明确区域/流域的耗水规律是水资源管理的基础和前提,为此,借助分布式水文模型研究了淮河中游北岸半湿润典型区的耗水规律。研究区主要的耗水方式为土表蒸发和植被蒸腾,约占总耗水的70%;人类活动所引起的水分消耗约占总耗水的12%;除了人类活动耗水外,其他耗水方式均与降水存在一定的相关性;耗水强度(耗水深)居民区最小(不考虑工业耗水),水域最大,且在空间分布上呈现向水域逐渐增大的趋势。基于水量平衡的水循环模拟为区域/流域耗水研究提供了一种新的途径,研究成果也为当地的水资源管理提供部分依据。

摘  要：
Water consumption management is the key to the strictest management system of water resources,and clarifying the rule of region/basin water consumption is the basis and premise of water management.In this paper,the water consumption of the typical sub-humid area in the north shore region of the Huaihe middle reach was studied with the help of a distributed hydrological model.Soil evaporation and vegetation transpiration are the main ways of water consumption in the study area,account for about 70% of the total water consumption.Water consumption caused by human activity is about 12% of the total quantity.Every way of water consumption has certain correlation with precipitation except human activity.Residential areas have the minimum water consumption intensity(or water consumption depth)in which the industrial water consumption is excluded.Water areas have the maximum water consumption intensity,and the water consumption intensity has the trend of increasing from other LUC to the water areas gradually in the spatial distribution.The water cycle simulation based on water balance provides a new way to study the region/basin water consumption,and the research results also provide some basis for the local water resources management.
