Low-flow resources impact analysis based on Guizhou karst multivariate statistical of land use type

In the karst basins,the unique basin system and the hydrology geology causes the influence of Low-flow resources factor to be extremely intriguing,besides the climatic conditions,plants and the environmental condition which the pad surface institute composes also had some thing with the waterless resources,the land type is one of the important factors which attribute respectively.The basin which controls by the independent hydrologic station is the statistical unit,withdraws and counts various basins the land utilization categorical data of various basins,with the aid of the Arcview software's computation function to determine drainage area as well as the land utilization type area's data,carried on the land utilization type characteristic through the SPSS software carries on the examination to the Low-flow resources influence multiple regression analysis and to the regression equation effect between the regression equation quota revelation land utilization type and the waterless resources relations.
