摘要
对福建省浦城县36a生栓皮栎人工造林效果进行了调查研究。结果表明,栓皮栎人工林具有较高的林分生产量,林分总生物量达266.560t/hm^2,乔木层为257.149t/hm^2;林分平均树高20.4m,平均胸径19.5cm,蓄积量达201.87m^3/hm^2。与杉木人工林相比,栓皮栎人工林具有良好的土壤结构和较强的养分供应能力。其表层土壤>0.25mm水稳性团聚体含量比杉木人工林高9.99％,土壤有机质含量比杉木人工林高0.695％。栓皮栎人工林还具有良好的水源涵养能力,林分总持水量比杉木人工林高10％。
In this paper, the effects of silviculture of 36 year - old oriental oak plantation in Puchen County, Fujian Province were studied. The results showed that the oriental oak plantation has high productivity, the stand biomass is 266.560t/hm2, the tree stratum biomass is 257.149t/hm2, the tree stratum biomass is 257.149t/hm2, the tree stratum biomass is 257.149t/hm2, the stand average DBH, height and volume are 19.5cm, 20.4m and 201.87m3/ hm respectively. And the stand has better soil structure character and has stronger nutriment supply ability, total content of >0.25mm Water-stable soil aggreagate of 0-20 cm top soil is 9.99 % highter than that of Chinese fir plantation and organic materials of 0-20 cm top soil is 0.695 % higher than that of Chinese fir plantation. Oriental oak plantation also has better function of water conservation, total content of water- holding of stand is 10% higher than that of Chinese fir plantation.
