摘　　要：运用巢式样方法对雾灵山自然保护区中的7个不同植物群落(Ⅰ.油松、Ⅱ.华北落叶松、Ⅲ.云杉林、Ⅳ.山杨林、Ⅴ.白桦林、Ⅵ.蒙古栎林、Ⅶ.紫椴落叶阔叶林)进行了数据调查,根据调查结果采用非饱和的曲线方程对雾灵山7种类型植物群落乔木拟合种-面积曲线,根据拟合结果确定了各个群落的表现面积:当精度达到100%时Ⅰ-Ⅶ乔木群落的基本面积分别为:653m2、461m2、978m2、719m2、891m2、913m2、803m2;而精度达到90%时Ⅰ-Ⅶ乔木群落的表现面积为:430m2、284m2、656m2、474m2、592m2、579m2、528m2。可见不同群落类型表现面积有很大的差异,群落表现面积随着精度的增大而增大。因此应在精度要求和综合分析各个群落的基础上确定乔木层的表现面积。This article uses nest patterns method to investigate the data of seven different plant communities in the Wuling Mountain Nature Reserve Area （ I . Pinus tabulaeformis, [I ~ North China larch, HI. Spruce for- est, IV. Aspen forest, V. Birches, Y[. Mongolian oak forest, ~. Linden deciduous broadleaf forests）. Based on the survey results, it estimates the species--area curves, according to the fitting results to determine the expression area of each communtty, when me precision , respectively653 m2,461 m2,978 m2,719 m2,891 m2,913 m2,808 m2. When precision reaches 900/oo ,the performance area of I -- ＂~ arbor communities arerespeetively 430 m2,284 m2,656 m2,474 m2,592 m2,579 m2,528 m2. Thus the conclusion can be drawn that different community types show differences in the performance area,andthecommu- nity area increases with the increase of precision performance. Sothe community area should be detemined by tree lay- er. on the basis of accuracy and comprehensive analysis.
