云南蔗区自然气候特点与生态区划

系统分析了云南甘蔗产区的自然气候条件和特点。根据作物生态区划的基本原理,以温度为一级指标,年降雨量、干燥度及农业意义为二级指标,将云南蔗区划为6个生态类型蔗区,即:北热带湿润区、北热带半湿润区、南亚热带湿润区、南亚热带半湿润区、中亚热带湿润区、中亚热带半湿润区,为云南甘蔗产业发展规划提供了科学的依据。

The Natural Climate Characteristics and Ecological Regionalization in Yunnan Sugarcane Area

The natural climate characteristics were analyzed in Yunnan sugarcane area.On the fundamental of crop ecological regionalization with the temperature as the primary guideline and rainfall per year,dryness and agricultural significance as the secondary guideline,the six ecological zones were compartmentalized in the Yunnan sugarcane area.i.e.the north tropic humid zone,the north tropic hemi humid zone,the south subtropical humid zone,the south subtropical hemi humid zone,the central subtropical humid zone,and the central subtropical hemi humid zone.This regionalization will provide a scientific basis for developing the Yunnan sugarcane industry.
