玉米种植分布与气候关系研究

从世界角度来看,玉米的种植范围仅次于水稻和小麦,可以看出其种植范围之广,并且产量较高,是我国当前第一大作物。许多研究表明,农作物对气候的变化影响非常敏感,而我国的玉米种植在很大程度上仍然依赖于农业气候资源,玉米的空间分布格局深受气候条件的影响。基于最大熵模型,本文对影响玉米种植分布的主导其后因子进行分析,并对我国玉米种植区分布的气候适宜性进行划分,为制定玉米应对气候变化的措施提供一定的科学依据。

Maize in China: The Relationship Between Planting Distribution and Climate

Corn is the world"s most widely grown cereal crops, rice and wheat acreage behind, but the first of the three cereal production ranks, has become China"s first major crops. Many studies show that the impact of climate change on crops is very sensitive, and our corn is still largely dependent on agricultural climate resources, spatial distribution pattern of corn by the effects of climate conditions. Maximum entropy model, this paper affect the distribution of corn dominant factor was subsequently analyzed and divided climatic suitability distribution of maize growing areas, provide a scientific basis for the development of maize response to climate change.
