摘要
十年两次间伐的连续观测表明,抚育间伐能促进黄山松林分的直径和单株材积生长:间伐林分总材积增加1%左右,经济价值提高33. 4%,乔木层生物量提高2～5%:不间伐林分9年株数枯损15. 15%,材积枯损4. 74%,凋落物以不间伐林分的最多,达10278kg/ha,其次为弱度和中度间伐林分.
Tending felling twice in ten years to Pinus Taiwanensis Plantation show-
ed the following effects:The growth of diameter and individual tree-volume
was promoted;the total stand volume in creased by 1%,the stand economic va-
lue raised by 33. 4% and the biomass of tree stratum by 2～5%.The quantity
of the dead timber and litter was also under consideration.
