| Abstract: | Making use of the climate data from 1961 to 2006 and geographical information of 90 weather stations in Guangxi, spatial analyzing model for indices of cold damage of early rice were built. Based on the GIS software platform, and using Guangxi fundamental geographic data on the scale of 1 to 250000, the indices of cold damage in Guangxi were reckoned on the little grids of 1 km x 1 km. the spatial distribution of cold damage for early rice in Guangxi were analyzed by the GIS technique, which gave out the divisional result of cold damage; zero, light, moderate and serious degrees, the assessment and suggestion for different cold damage regions were put forward. |
