摘　　要：以赣无系列油茶良种为研究对象,集成网络上公开的经济林数据和地理空间数据,将地理环境变量表达为空间上连续的地理栅格单元,并通过GIS栅格数据模型和空间分析的方法进行信息挖掘,构建了应用地理栅格的赣无系列油茶良种适宜种植区域评价方法;对典型的原产地、种植地进行遥感图像解译获取地理栅格地图,利用数理统计和样本点的方法计算生态幅,同时进行多个环境栅格变量的空间交集运算和空间分析处理,评估赣无系列油茶良种的种植适宜区域。结果表明:①利用构建的评价方法,可将油茶良种的栽培种植适宜区定位分析到小尺度的地理区域上;②赣无系列油茶良种适宜种植区域,主要包括湖南、江西、浙江省的大部区域以及南方其他省份的部分区域。With Ganwu Camellia as the research object, integrated with economic forest data and geospatial data published on the network, the geographical environmental variables were expressed as spatially continuous raster units. We carried out through the model of raster and spatial analysis methods to construct an evaluation method for suitable planting areas of Ganwu Camellia . Remote sensing interpretation of typical origins and planting areas was used to obtain raster maps, and mathematical statistics and sample points were used to calculate ecological breadth. At the same time, the calculation of spatial intersection and analysis processing of multiple environmental variables were carried out to evaluate the suitable areas for planting Ganwu Camellia . By using the constructed evaluation method, the suitable areas for cultivation and planting of Ganwu Camellia could be analyzed on a small-scale geographic area. The suitable planting areas for Ganwu Camellia mainly include Hunan, Jiangxi and Zhejiang Province and some areas in other provinces in the south of China.
