摘要
对福建三明不同更新方式的米槠林经营效果进行定量评估。结果表明:林分蓄积连年生长量、林分生产力:人促更新>人工造林>天然更新;林分生物量:人促更新>天然更新>人工造林。营林生产每hm2、每年投资:人工造林>人促更新>天然更新。活立木蓄积年增长经济价值和间接经济价值:人促更新>人工造林>天然更新。3种更新方式的林分间接经济价值远大于直接经济价值。
This paper evaluated their management values in different regeneration patterns of Castanopsis carlesii forest in Sanming, Fujian. The results indicated that the change regular of the productivity of stock and stand of Castanopsis carlesii forest was A. M. P. R. stand 〉 A. R. stand 〉 N. R. stand; and the regular of biomass of stand was A. M. P. R. stand 〉 N. R. stand 〉A. R. stand; and the annual investment per hm2 was A. M. P. R. stand 〉A. R. stand 〉 N. R. stand;and the an- nual gain of standing wood per hm2 was A. M. P. R. stand 〉 A. R. stand 〉 N. R. stand. The indirect economic values were far greater than the direct economic value of standing forest of the three different regeneration patterns.
