This paper expatiated on define,function and correlative technique index of soil water reservoir,made certain its research depth,and calculated static state capacity of soil water reservoir.The results showed:In 5 m depth soil of research area,total holding capacity is 1 419.78 mm/416.156 million m3.Unavailable volumetric capacity is 21.08% of total holding capacity.Gravitational volumetric capacity is 13.82% of total holding capacity.Available volumetric capacity is 65.10% of total holding capacity.The greatest available volumetric capacity is 78.92% of total holding capacity.
