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 waterlogging of the surface in the region. Combined using the spatial analysis in GIS with calculating the Isochrones in the confluence of regional waterlogging, 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-loggings confluence. The research evidence that the confluences strength in time is closed to the elevation of the research region, and the confluences distribution in space is closed to the distribution of the river.
