| 摘 要： | 通过应用气候生产潜力估算模式,结合气候资源的GIS空间分析方法,探讨了广西冬季的气候资源分布特征,估算了该时期冬作系统的生产潜力,并对各冬种时期(从11月上旬到次年3月下旬)的冬作区域适宜性进行了分析。结果表明,广西冬季气候资源基本呈南多北少、东多西少分布趋势,冬作主要以发展马铃薯为主,南部兼顾发展番茄。百色右江河谷和南部沿海一带积温比同纬度地区的偏高300℃,热量资源丰富,因此适宜在该区域建立冬种发展的主基地。

| Abstract: | Using evaluation modes of climatic potential productivity and combining with the method of GIS spatial analysis,the distribution characteristics of climatic resources in Guangxi region during winter was explored,the potential productivity and the regional adaptation capacity of winter crops system during the cultivation period of winter crops(from the early November to the late next March) were also estimated.The results show that the distribution of Guangxi climatic resources in winter are more in the South than North and more in the East than West,the winter crops are mainly in potato,and taking into account the development of tomato in the South.The accumulated temperature in the region of Youjiang River Valley in Bose areas and the southern coastal areas of Guangxi,in which the thermal resource is abundant,is over more 300 ℃ higher than regions in the same latitude,therefore,it is appropriate to construct main bases for winter crops development in those areas. |
