浙江省棉花农业气候区划

Regionalization of Agricultural Climate for Cotton Growing in Zhejing Province:

本文分析了影响浙江省棉花生产丰、歉的气候因素,选用积温和春、秋两季降水量2个关键性气候因素作为区划指标;并按热量指标将其区分为植棉热量适宜区和热量不足区;以水份为指标又将热量适宜区区划为适宜区、适宜亚区、次适宜亚区和不适宜区。

Two key factors,cumulative temperature and precipitation in spring and autumn were chosen as the indexes for regionalization on the basis of the analysis on the climatic factors affecting good or short coming harvesting for cotton production in Zhejiang Provincc.According to the extent of the climatic condition fitting for cotton growing,the province was regionalized to 4 regions,i.e.most suitable (no). suitabl, sub-suitable and not suitable regions for cotton growing. Some suggestions on the rational distribution for cotton growing have been made in line with the results of the regionalization.
