The research progress of climate suitability at home and abroad was briefly reviewed in this paper,which was divided into three stages:The initial stage of research,the initial development and application stage,and the application research warming stage. The main achievements and progress of climate suitability in China were also introduced from three aspects as follows:Improvement of climate suitability model,extension of climate suitability applications and development of climate suitability model. Based on the impact of climate change on agriculture and the weak links in climate suitability research,the focus and hotspot of future climate suitability research were proposed,which will be five important directions:The climate suitability model proceed from crop growth model,the climate suitability research proceed from characteristic agriculture,the climate suitability research proceed from climate change,the climate suitability model based on different theories and the climate suitability evaluation index research.
