为了解薛公岭自然保护区辽东栎(Quercus liaotungensis)的天然更新情况,采用样方法进行了调查。结果表明:本保护区内辽东栎的更新总量随着郁闭度的增加呈现先增加后降低的趋势,在0.6~0.7的郁闭度下总量最多,比>0.9的郁闭度提高了33.5%;坡上比较适合辽东栎的更新生长,更新总量最大,达到7 967株/hm2;陡坡的辽东栎的更新总量最大,比平坡提高了35.6%;辽东栎最适宜在半阳坡上生长,更新总量为8 356株/hm2,阳坡和半阳坡差异不显著。综合郁闭度及地形条件的调查结果,辽东栎更新最适宜的郁闭度为0.6~0.7,地形条件为坡上、陡坡、阳坡及半阳坡。
To understand the natural regeneration of Quercus liaotungensis in Xuegongling Nature Reserve, a sampling method was used to investigate the natural regeneration of Quercus liaotungensis. The results showed that the total amount of Q. liaotungensis in the reserve tended to increase at first and then decrease with the increase of canopy density. The total amount of canopy was the highest under 0.6 ~ 0.7 canopy density, and the canopy density ratio> 0.9 increased 33.5% of the total area. The slope was more suitable for the regeneration and growth of Quercus liaotungensis. The total amount of regeneration was the highest, reaching 7 967 plants / hm2. The total amount of Quercus liaotungensis on the steep slope increased 35.6% Slope growth, the total updated amount of 8 356 plants / hm2, sunny and semi-sunny slope difference was not significant. Based on the survey results of canopy density and topography, the most suitable canopy closure degree of Q. liaotungensis is 0.6-0.7. The topographic conditions are slope, steep slope, sunny slope and semi-sunny slope.
