摘要

根据水文汇流理论，探讨了该地区地表内涝的计算方法。利用GIS空间分析与计算区域内涝汇合点等时线相结合，描述汇合点在空间上的分布和汇合点在时间上的强度。在游行的最后，给出了内涝汇流时空分布的时空图。研究表明，汇流在时间上的强度与研究区海拔高度接近，汇流在空间上的分布与河流的分布接近。

GIS-Based Spatial and Temporal Analysis of Regional Water-Logging Confluence

According to the confluence theory of hydrology, the paper discuss the method of calculating the water-logging of the surface in the region. Combined using the spatial analysis in GIS with calculating the "Isochrones" in the confluence of regional water-logging, to describe the distribution of the confluence in space and the strength of the confluence in time. At the end of the procession, it gives the space and time maps of spatial and temporal distribution of the water-logging's confluence. The research evidence that the confluence's strength in time is closed to the elevation of the research region, and the confluence's distribution in space is closed to the distribution of the river.
