摘　　要：本文运用ARC/INFO地理信息系统结合趋势面分析,对福建省大田桃源林场引种的25年生的89个马尾松种源的树高、胸径、材积的地理变异进行空间分析和基于GIS的表述。研究结果表明:各种源树高生长的趋势面高值区主要分布在福建、江西、湖南的南部,广西的东部及广东。各种源胸径和材积生长的趋势面高值区在广西中部、南部,广东、福建和江西三省交接地带。从上面的结果可以看出,马尾松的高产种源主要分布在我国广西的中南部和广东、福建和江西三省交接地带。这为马尾松种源的合理区划和种子调拔提供了理论依据。In this paper,the geographical variation of height,diameter at breast height and timber volume of 89 species of 25-year-old provenances of Pinus massoniana planted in Taoyuan Stated-own Forest Farm of Datian County in Fujian Province were spatially analyzed and described based on GIS by using ARC/INFO geographic information systems combined with trend surface analysis.The results showed that the high-value areas of trend surface in height growth were mainly distributed in Fujian Province,Jiangxi Province,the southern part of Hu,nan Province,the east of Guangxi Province and Guangdong Province;the high-value areas of trend surface in diameter at breast height and timber volume were mainly distributed in central and southern areas of Guangxi Province,and the joint zone of Guangdong,Fujian and Jiangxi Province.From the above results,the conclusion can be drawn that high-yielding provenances of Pinus massoniana were mainly located in central and southern areas of Guangxi Province,and the joint zone of Guangdong,Fujian and Jiangxi Province.It provided theoretical basis for reasonable division and seeds adjustment provenances of Pinus massoniana.
