- Abstract:
-
Monthly rainfall data in 16 meteorological stations in Poyang lake basin through 1960 to 2008 were used to analyze spatial distribution of rainfall based on geostatistic and GIS technology. The results show that: (1) the spatial distribution of the average annual rainfall shows an increasing tendency from the southwest to the northeast and from the northwest to northeast; (2) the high value center of inter-generational rainfall have generally arisen in Lushan Mountain and Yushan, and the low value center of that occurs in Ganzhou, Suichuan of the southern of Jiangxi; (3) spatial analysis of the seasonal rainfall change shows that the seasonal average annual rainfalls belong to a weak or moderate variability level. In addition, it is good to make use of Gaussian model to simulate spatial distribution of seasonal rainfall, so Gaussian model should be used for seasonal rainfall spatial interpolation.
