Abstract:

With the development of science and technology and social economy, the connotation of climate resources has changed significantly. Deepening the understanding of climate resources was an urgent need to promote agricultural development. Authors reviewed the conceptual evolution of agricultural climate resources, their connotations and characteristics, and summarize the new situation of agricultural climate resources and their utilization in the context of climate change. The results showed that: (1) agricultural climate resources were the climate resources and climate environment that could be used by agriculture in the climate system, including the dynamic changes of material, energy, information and other forms and their space−time. They were an essential part of the natural resources of agricultural. (2) As a part of climate resource, the common characteristics of agricultural climate resources included: infinite cycle of renewable and limited in a certain space−time range, borderless wide distribution and regional imbalance, continuity, periodicity and unstable fluctuation interdependent constraints and irreplaceability, nonsubstance, resource value of multiple suitability and relativity. Unlike other types of nonlinear resources, it was characterized by nonlinearity, correlation, synergy and potential value. (3) Climate change had brought new trends to China's agricultural climatic resources and active adaptation to climate change was the basic principle that should be adhered to in the development and utilization of China's agricultural climatic resources at present. The main methods were: dynamic and moderate adjustment, taking care to leave room. The three diversities of agricultural biology, climate and agricultural activities, were coordinated. Taking full advantage of modern technology focused on the development and utilization of agricultural climate resources in the form of information. Based on agricultural climate resource surveys and refined zoning, regional climate response technology systems for crop cultivation and animal health feeding should be constructed.
