Suitability of agro-climate;subordinative-degree function;systemic analysis;model of agro-climatic suitability

With the dynamic characteristics and systematicness, the theory of suitability-degree of agro-ecological climate resources opens up a new way for systematic analysis of agro-ecological climate resources. During last 20 years, the research on suitability of agro-ecological climate resources had been improved in the following aspects: (a) the curves, states and functions of subordinate-degree of climatic element have been established; (b) the model of agro-climate subordinate-degree has been established; (c) the agro-ecological climate resources on different regional scales have been regionalized and clustered; (d) the guidance of the theory of suitability-degree of agro-ecological climate resources for agriculture production has been explored. In the future, research on the suitability-degree of agro-ecological climate resources will focus on the following aspects: (a) establishing and forming better states and functions of agro-climatic subordinate-degree; (b) improving the model of subordinate-degree of agro-ecological climate resources; (c) enhancing research on application of systemic analysis of agro-ecological climate resources.
