    Influence of Underlying Surface Change on Hydrogeological Conditions in Arid and Semi-arid Regions

    • 摘要: 土地利用格局的变化导致了流域下垫面环境的改变,进而对该地区水文循环的源汇项产生了影响,对地下水位也产生了较大的影响。为研究下垫面变化与地下水位的关系,对不同时期的海流兔河流域遥感影像进行定量化分析,收集了长序列地下水监测数据,通过计算不同土地类型的转移矩阵,绘制地下水位变幅图,在此基础上,对不同土地类型转移量的地下水位及影响因素进行了分析。结果表明:地下水位变化主要受到下垫面变化的影响;土地利用类型时空转换强烈,土地利用类型变化剧烈的地区均是地下水位急剧变化的区域,说明土地利用类型的变化对下垫面影响较大,和地下水位空间分布存在正相关性。

       

      Abstract: To study the relationship between landuse change and groundwater level, the transfer amount of land use change has been calculated by using transfer matrix based on the remote sensing images of the Hailiutu river basin in different periods. The spatial distribute on map of groundwater level and land use types have been obtained by combining the groundwater monitoring well data and geo-statistics in the catchment of the river, and the spatial and temporal variation of groundwater level and the effect of land use change on groundwater level have been analyzed in this paper. The results show that the variation of groundwater level presents obvious spatial distribution characteristics and the human factors have increased influence on the spatial variation of groundwater level; the land use type in this area has in tense spatial and temporal conversion, and the land use type changes violently in the area where the groundwater level changes sharply, indicating the reispositive correlation between the type change of land use and the spatial distribution of groundwater level.
