松嫩平原水文地理区划与分析

Analysis of Hydrogeological Regionalization in Songnen Plain

水文地理区划是对研究区水资源进行开发与利用的基础。为了给松嫩平原地下水的开发与利用以及地下水资源量的计算提供参考,在总结松嫩平原现有水文资料的基础上,运用Arc-GIS将松嫩平原进行地形地貌、行政、流域、生态以及含水层分区,并对松嫩平原含水层与地形地貌进行双因素耦合,得出24个子区;对松嫩平原地形地貌、含水层以及流域进行三因素耦合,得出70个子区。松嫩平原水文地理区划的明确,能够更准确地计算松嫩平原降雨入渗以及含水层之间相互补给的问题。

Hydrogeographical regionalization is the basis for the development and utilization of water resources in the study area,providing reference for the conservancy and exploitation of groundwater and the calculation of groundwater resources in Songnen Plain.On the basis of summarizing the existing hydrological data of Songnen Plain,Arc-GIS was applied to divide the Songnen Plain into topographical,administrative,watershed,ecological and aquifer areas,and 24 sub-areas were obtained by coupling the aquifer and topography and 70 sub-areas were obtained by coupling topography,aquifer and watershed.It can more accurately calculate the rainfall infiltration and mutual recharge aquifers in Songnen Plain.
