【摘要】 为达到将南亚热带名优晚熟果树引种至其地理北界的目的,对闽东地区的果树区域选择,进行新的技术应用,拟提高其区划精确性,具体做法是采用GIS技术,对福鼎、霞浦等闽东地区,坡度小于25°、朝南坡向、温度模型适宜的避冻区域及山地相对高差在0.5～0.8之间的区域,进行晚熟果树生态区域选择,并制作相应的专题图和区域面积统计。最终区划结果符合技术实现要求。更多还原

【Abstract】 Aiming at introduce latterly mature fruit tree to her northern boundary, we get to zone selection by new techniques in order to improve its precision. Applying GIS, suitable ecological zone selection comes true, and some pictures about special topic were made, according to factors: less than 25° gradient, towards south, suitable temperature avoiding frost, relative height between 0.5 and 0.8.Results adapt to techniques applying requests.更多还原
