闽西北不同类型毛竹林生物量分布格局
The biomasss distribution of different Phyllostachys edulis forest types in Northwest of Fujian Province
摘要
Abstract
The distribution pattern of biomass was studied in pure bamboo stand (I), bamboo stand mixed with broadleaves trees (II), and bamboo stand mixed with coniferous trees(III) in Yong'an county, Fujian Prov ince. The result showed that the biomass and productivity of bamboo forest was in the order of I > II >III . The biomass of I, II ,and III was 143 418.06, 135 469.53, and 131 782.78 kg·hm-2, respectively. The productivity of Ⅰ,Ⅱ,and Ⅲ was 59 786.55, 54 921.44, and 38 418.68 kghm-2·a-1, respectively. The productivity of pure bam boo stand was higher than that of other bamboo forest types. The biomass distribution was different with different bamboo forests types. The stem mass fraction in pure bamboo forest was higher than the fraction in forest II and III, while the mass fraction of bamboo root and leaf was lower. The more economic benefits come from the higher stem mass fraction in forest I. The characteristics of bamboo number and biomass were different in different bamboo forest types. The DBH of I and II forest was mainly between 10.5 cm and 12.5 cm and biomass ac counted for 54.25% and 53.71% of forest I and Ⅱ. The DBH of Ⅲ was mainly between 9.5 cm and 11.5 cm and biomass accounted for 54.34% in forest HI. The biomass and productivity of bamboo stand mixed with broad-leaves trees was higher, meanwhile the bamboo stand mixed with broadleaves trees had better physical and chemical properties of soil and better nutrient cycling characteristics. The bamboo stand mixed with broadleaves trees may be a better cultivation pattern.关键词
