| 摘 要： | 利用GIS技术开展八角种植适宜性气候区划的步骤和方法.根据八角生产对气候、地形等环境条件的要求,确定八角种植的适宜性区划指标;利用广西90个气象台站的气候资料和1∶25万地形数据,通过建立区划指标数学模型的方法,将区划指标因子推算到1 km×1 km细网格单元上,实现了气候资源分布的细化;采用GIS技术划分出八角种植的最适宜、适宜、次适宜和不适宜区,给出了细网格区划专题图,为八角的合理布局和发展提供了气候科学依据.

| Abstract: | It was introduced that the steps and method of climatic fitness division for Illicium verum Hook.f.planting with GIS technique.According to the growth requirement of I.verum to the environmental conditions such as climate and landform,it was decided the fitness index for I.verum planting.Using the climatic data recorded by the 90 weather stations in Guangxi and the data of landform on the scale of 1∶250 000,by the method of building mathematical model for division index,the index was reckoned to little grids of 1 km×1 km.With GIS technique,Guangxi region was divided into the fittest,fit,less fit and unfit climatic regions for planting of I.verum,and special maps on little grids was drawn.It provided climatic scientific basis to reasonably distribute and develop the planting of I.verum. |
