人促米槠、闽粤栲速生丰产林调查研究报告

顺昌县郑坊乡榜山村14.9hm~211年生人促米槠速生丰产林的树高、胸径蓄积量及生物量（干重）平均生长量分别为1.07m·a~（-1）、0.66cm·a~（-1）、18.0m~3·hm~（-2）·a~（-1）及10.78t·hm~（-2）·a~（-1）;顺昌县际会乡谢屯村13.1hm~210年生人促闽粤栲速生丰产林平均生长量分别为1.31m·a~（-1）、0.88cm·a~（-1）、23.5m~3·hm~（-2）·a~（-1）及11.64·t·hm~（-2）·a~（-1）。本文还对其林分起源、树相、树种组成、径阶分布等进行详细的研究。

A Report on Investigation of the Artificially Stimulated Fast-growing and High-yield Broad-leaf Forests

The investigations were made on 11 years' Castaopsis carlesii stand and 10 years' C. fissa stand, whose natural regeneration is accomplished by means of artificial stimulating, respectively in Banshan, Zhengfan, Xietun and Jihui, Shunchang County. And it is shown that, for C. carlesii stand, the average annual increment of height, dbh, volume and biomass ( dry weight ) of the stand are respectively 1.07ma-1, 0.66cm·a-1, 18.0m3·hm-2·a-1and 10.783t hm-2a-1, the mean breast height form factor is 0.535 and the total investment is 322 yuan·hm-2, and for C. fissa stand, the corresponding fignres are respec -tively 1.31m·a-1, 0.89cm·a-1, 23.5m3·hm-2·a-1, 11.635t·hm-2·a-1, 0.588 and 322yuan·hm-2. The results show that two stands are of the fast-growing and high-yield broad-leaf forests. The studies of stands origin, forest form, species composition, diameter distribution, growth process of average tree were also conducted.
