摘要
滇中亚热带山地主要森林群落取样的最小面积:常绿阔叶林 400m^2(20×20m)～361m^2(19×19m);云南松林 324m^2(18×18m);华山松林 289m^2(17×17m)～324m^2(18×18m);滇油衫林 289m^2(17×17m)～324m^2(18×18m)。采用400m^2(20×20m)的样方面积可满足该地区一切森林群落取样的需要。
The minimun areas of the sampling forest are as follaws: Evergreen broad-leaved forest 400m^2 (20×20m)~361m^2 (19×19m), Pinus yunnanensis forest 324m^2(18×18m), Pinus armandii forect 289m^2 (17×17m) ~324m^2 (18×18m), and Keteleeria evelyniana forest 289m^2(17×17m)~ 324m^2(18×18m). The sampling area 400m^2(20×20m) is applicable all to the forest com- munities in the region.
