| 摘 要： | 采用定位实测法,对辽东山地老秃顶子濒危植物双蕊兰居群斑块栖居的森林群落及土壤环境特征以及森林枯落物和土壤环境的小尺度空间变异性进行了定量研究.结果表明:(1)双蕊兰居群斑块栖居于蒙古栎(Quercus mongolica)+色木槭(Acer mono)+紫花槭(Acer pseudo-sieboldianum)落叶阔叶林中,群落环境以庇荫凉湿为主要特点;(2)双蕊兰居群斑块内覆盖有厚度为5.8~9.0cm的森林枯落物,枯落物中所含C、N、Si、Ca、Al、Fe、K、Mg、S、Mn、P元素的平均含量分别为64.84%、9.23%、8.87%、8.68%、2.32%、2.13%、1.30%、0.62%、0.47%、0.41%和0.24%,变异系数分别为15.5%、15.3%、72.7%、10.1%、79.5%、57.2%、61.8%、21.5%、12.4%、25.1%和6.6%;(3)双蕊兰居群斑块内棕壤土层厚约60cm,pH为6.22,土壤中SiO2、CO2、Al2O3、K2O、Fe2O3、Na2O、CaO、MgO、N、SO3、P2O5和MnO的平均含量分别为50.86%、26.02%、12.07%、2.44%、2.41%、1.78%、1.56%、0.99%、0.81%、0.19%、0.13%和0.11%,变异系数分别为7.1%、17.1%、6.0%、10.1%、2.5%、6.0%、13.7%、1.7%、12.3%、14.7%、2.2%和2.0%.

| Abstract: | By using the positioning measurement method ,the authors studied the characteristics of forest communities and soil environment ,forest litter and the small scale spatial variability of soil envi-ronment quantitatively of endangered plant Diplandrorchis sinica population in Mt .Laotudingzi of eastern Liaoning Province .The results show that ：（1）Patchy distribution area of Diplandrorchis sini-ca population inhabited in deciduous broad-leaved forest with Quercus mongolica＋ Acer mono＋ Acer pseudo-sieboldianum .Shady ,cold and wet is the main characteristics of the community environment ;（2）There is forest litter covered on the Patchy distribution area of Diplandrorchis sinica population w hich thickness is 5 .8 to 9 .0 cm ,forest litter contains several elements such as C ,N ,Si ,Ca ,Al ,Fe , K ,Mg ,S ,Mn ,P and their average contents are 64 .84% ,9 .23% ,8 .87% ,8 .68% ,2 .32% ,2 .13% , 1 .30% ,0 .62% ,0 .47% ,0 .41% ,0 .24% respectively ,coefficient of variation is 15 .5% ,15 .3% , 72 .7% ,10 .1% ,79 .5% ,57 .2% ,61 .8% ,21 .5% ,12 .4% ,25 .1% ,6 .6% ,respectively ;（3 ）T he brunisolic soil’s thickness is 60 cm of the patchy distribution area of Diplandrorchis sinica population ,pH is 6 .22 ,contains SiO2 ,CO2 ,Al2 O3 ,K2 O ,Fe2 O3 ,Na2 O ,CaO ,M gO ,N ,SO3 ,P2 O5 and M nO ,their average contents are 50 .86% ,26 .02% ,12 .07% ,2 .44% ,2 .41% ,1 .78% ,1 .56% ,0 .99% ,0 .81% ,0 .19% , 0 .13% ,0 .11% respectively ,coefficient of variation is 7 .1% ,17 .1% ,6 .0% ,10 .1% ,2 .5% ,6 .0% , 13 .7% ,1 .7% ,12 .3% ,14 .7% ,2 .2% ,2 .0% ,respectively . |
