摘  要:
在喀斯特地区,独特的流域系统及水文地质使影响枯水资源的因素极其错综复杂,除气候条件外,各种下垫面所组成的环境条件也对枯水资源产生影响,土地利用类型是其中的一个重要因素。在分析土地利用类型对枯水资源影响时,以单独的水文站所控制的流域为统计单元,提取和统计各流域的土地利用类型数据,借助Arcview软件的计算功能确定流域面积以及土地利用类型面积的数据,通过SPSS软件进行土地利用类型特征对枯水资源影响的多元回归分析并对回归方程的效果进行检验,研究结果表明,回归方程定量地揭示了土地利用类型和枯水资源之间的关系。

摘  要:
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.
