摘　　要：根据枇杷生长发育与气象条件的关系,确定了影响枇杷种植的气候生态区划指标,并建立了各区划指标与经度、纬度和海拔的多元回归模型。应用混合插值法完成了区划指标的细网格化,采用加权指数求和法,建立区划评估模型,借助GIS技术制作枇杷种植精细化的气候生态区划图。结果表明:适宜种植区占评价区域的16.26%,主要集中在杭州东部的平原地区;一般适宜区占评价区域的16.27%,主要在杭州东北部的杭嘉湖平原和沿富春江周边的低丘陵地区;但是杭州将近70%的面积都不适宜枇杷种植,主要在杭州西部海拔较高的山区。According to the relationship between loquat growth and meteorological conditions,the climatic ecological division indices were defined for loquat planting,and the multiple regression models of various division indices were established by using the longitude,latitude and altitude as variables. These indices were refinedly gridded by the mixed interpolation method,the division evaluation model was established by using the weighted index sum method,and the refined division map for loquat planting was drawn by GIS technology. The results showed that： the areas suitable for loquat planting were mainly distributed in the eastern plain of Hangzhou,and accounted for 16.26% of the evaluated area; the sub-suitable areas accounted for 16.27%,and were distributed chiefly in the Hang-Jia-Hu plain of northeastern Hangzhou and the low hilly area along the Fuchun River; the unsuitable areas accounted for about 70%,which were distributed in mountain area of western Hangzhou.
