摘    要:采用标准木法(乔木层)及样方收获法(灌木层、草本层、枯落物层),研究了马尾松低效林的4种混交林及马尾松纯林的生物量及其分配规律。结果表明:马尾松-木荷、马尾松-板栗、马尾松-南酸枣、马尾松-枫香4种混交林的乔木层生物量分别为135.501、31.499、22.138及69.725t/hm^2,而马尾松纯林的生物量为37.043t/hm^2。在各器官生物量组成中,干材生物量最大,占总生物量的40.39%~74.87%,其他组分所占的比例依次为枝(11.40%~32.67%)、叶(9.31%~26.94%)。马尾松纯林的林下植被生长旺盛,其生物量高达6.649t/hm^2;而马尾松一木荷混交林的林下植被生物量仅为3.825t/hm^2。枯落物生物量则是马尾松-木荷混交林的最多,马尾松一枫香混交林最少。所有林分的生物量平均值为68.095t/hm^2。

关 键 词:马尾松  低效林  生物量  混交林

Abstract:By the methods of sample tree(for tree layer) and quadrat yield(for shrub layer,herbaceous layer and humus layer),the biomass of four deteriorated Pinus massoniana mixed stands and one pure P.massoniana plantation and its allocation were studied in this paper.The results showed that the biomass of tree layer in the mixed forest of Schima superba and P.massoniana,Chinese chestnut and P.massoniana,Sour jujube and P.massoniana,and Liquidambar formosana and P.massoniana was 135.501 t/hm2,31.499 t/hm2,22.138 t/h...
Keywords:Pinus massoniana  Deteriorated forests  Biomass  Mixed forest
