Research Advances and Assessment Review on Agroclimatic Resource Divisions in China
-
摘要: 在回顾我国近几十年农业气候资源区划研究工作的基础上,着重评述了经典区划方法及其缺陷,并列举了现行的(如统计数值化方法、3S信息技术等)各种新技术方法。还展望了农业气候资源区划需要深入研究的关键问题:必须首先解决科学选取具有气候物理与农作物生物机理相结合的区划指标体系,在先进的数值化区划方法前提下,借助于以3S为代表的遥感技术和信息技术平台,实现精细化农业气候资源区划。Abstract: 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.
