摘　　要：城市水源地保护是社会经济发展的关键,目前对水源地保护的研究主要集中于水环境质量和水资源数量两个方面。从水源涵养能力角度出发,以松华坝水源区为研究典型区,对不同土地利用类型土壤层对水源涵养能力的影响进行研究,得出不同土地利用类型条件下土壤容重、自然含水量、饱和含水量、有效涵蓄量、涵蓄降水量、毛管孔隙度、非毛管孔隙度、总孔隙度、毛管蓄水量、非毛管蓄水量、全磷含量、全钾含量和有机质含量等指标的变化规律。在此基础上,定量分析不同土地利用类型土壤层对水源地的涵养能力,并进行综合评价,以期从水源涵养的角度为水源地水资源数量保护策略的制定提供科学依据。It is essential for social and economic development to protect urban water sources.At present,the research on water source protection mainly focuses on two aspects: quality of water environment and quantity of water resources.From the aspect of water conservation capacity,this paper takes Songhuaba water source area as the typical area,and studies the influence of soil layers in various land use types on that capacity.Meanwhile,an attempt is made to get the changing process of the indexes from various land use types,such as soil bulk density,natural water content,saturated water content,effective water conservation amount,water conserving precipitation,capillary porosity,non capillary porosity,total porosity,capillary storage,non-capillary storage,total phosphorus content,total potassium content and organic matter content,etc.On this basis,quantitative analysis and comprehensive evaluation of water conservation capacity of soil layers in various land use types should take place to provide a scientific basis for the formulation of water resource protecting strategy in water source area from the aspect of water conservation.
