The Rainstorm Space and Time Characteristic Analysis Based on GIS

Base on the theory of rainstorm and flood, concept of spatial image and geographical, the elementary and computing technique foundation of gis. In experimental plot data quite complete situation, Summary science reasonable, both accurate and highly effective rainstorm flood space and time structure evolution rule research technique, And key discussion and research spatial data pretreatment and quality analysis, space and time structure differentiation analysis, spatial reckoning analysis, spatial pattern analysis and spatial autocorrelation analysis in rainstorm flood space and time structure evolution research concrete application.
