The analyzed results show that it is a concise,precise project and well fitted with terrain spatial interpolation project of temperature under complicated terrain conditions. For eliminating the effect on precipitation from terrains, the project that all the elements concerned with the interpolation are unified on the same height and the terrain characteristics are taken into account has been put forward, which also displays a better effect. Furthermore, the results analyzed spatially of the climatic elements under the different special resolution have been investigated , which denotes that the resolution of 4km is the most suitable for the research on the hydrologic processes of the Changjiang River drainage area and is prone to coupling with the regional climatic model.
