Research Advances and Assessment Review on Agroclimatic Resource Divisions in China

Based on the review of researches on agroclimatic resource divisions in recent decades, the classical division methods and their defects are assessed. The current new techniques such as statistical numerical method, GIS, RS,GPS techniques, etc. are described with examples as in the Appendix. The key issues related to the agroclimatic resource divisions that need studying in great depth are discussed. The first issue which needs resolving is a scientific selection of index system of division that combines climate physics with crop biological mechanism. Using the advanced numerical division method, refinement of the agroclimatic resource divisions can be achieved with the aid of remote sensing and information techniques typically represented by GIS, RS,GPS.
