Abstract: During the past 100 years, the global climate has experienced a major change——become warmer and warmer. Along with this change, its influence has become increasingly remarkable. How to adapt to this change has been a world concerned hot spot. China has abundant practices on adjusting agricultural planting structure to adapt to climate change, but systemical carding is lacking. There is no clear cognition about the rich connotation on the existing practices to adapt to climate change. In order to better reply to climate change, this paper expounded the effect of climate change on China adjustment of agricultural planting structures from the following 3 aspects, including cropping system, crop distribution, cultivars layout. The paper also discussed the connotation on different ways of adjusting agricultural planting structures for adapting to climate change, including multiple-crop index, inter-cropping model, crops collocation, boundary of planting, proportion of crops, drought resisting varieties, disease and insect pests resistant varieties, combining with the typical cases, such as expansion of rice and corn planting areas in Northeast China, moving boundary of winter wheat further north, “two-later” technology in North China, changing double cropping rice in the middle and lower valley of the Yangtze River, exploiting winter agriculture in Southern China, etc.. The key issues facing the adjustment of agricultural planting structure for adapting to climate change were put forward. Studies on integrated impacts of each climate change factor on adjustment of agricultural planting structures should be further enhanced. The agricultural exquisite regionalization, optimal allocation of crops layout, and multi-objective breeding decision should be studied in depth.

Key words: climate change, adaption, planting structure, cropping system, crops distribution, cultivar layout
