利用GPS绕测,定位南方铁杉分布边界的坐标,输入GIS系统中绘制分布图并求算面积。发现江西武夷山国家级自然保护区的南方铁杉主要分布在海拔1 300～2 000 m的阴坡或谷地,最大株胸径有127.0 cm,最高分布于海拔2 070 m,分布最低海拔1 105 m,自然更新良好,分布面积达1 560 hm2,全国罕见。

The boundary coordinate of distribution of Tsuga chinensis var.tchekiangensis was positioned by the GPS,the coordinate was input GIS system to draw distribution figure and calculate area.The results showed that T.chinensis var.tchekiangensis of Jiangxi Wuyisahn national nature reserve was mainly distributed in the shade slope or valley in south of the elevation of 1 300 ~ 2 000 m,the biggest diameter at breast height（DBH） was 127.0 cm,highest altitude of distribution was 2 070 m,and the lowest was 1 105 m,natural update was good,the distribution area of 1 560 hm2,It was the rare distribution of T.chinensis var.tchekiangensis.
