析模型,应用 ArcGIS 的空间分析和多层复合方法,制作广东双季稻种植适宜性区划专题图,
将区划分为最适宜、适宜、次适宜、不适宜四个等级并就各区水稻生长气候条件优劣进行评
述,提出了有针对性的生产建议,为广东双季稻种植生产布局提供科学依据。

Abstract: Using of 86 weather stations Climate data from 1980 to 2012 and data of geographic
information in Guangdong Province, according to the requirement of the eco-climate conditions
for Double-Crop-Rice, accumulative temperature (≥10℃) ,the growth period of safety and
number of days 10℃ to 15℃ were chosen as the planting climatic suitability and regionalization
indicator of Double-Crop-Rice in Guangdong. The spatial analysis model of the indicators were
constructed with longitude, latitude, altitude, and other geographic information, and the planting
suitability regionalization thematic map of Double-Crop-Rice was produced in Guangdong with
