福建中部沿海山地生态林建设中混交造林树种搭配试验研究

对福建中部沿海山地不同树种混交造林进行试验研究。结果表明:不同树种搭配由于种间关系及树种适应性差异,混交林的经营效果不同,以火力楠、福建柏、木荷和枫香4个树种为主林木,以湿地松和台湾相思为伴生树种是该区营造混交林较为适宜的树种,在生态林建设中应用是可行的。针对福建中部沿海山地的土壤条件状况,结合树种适应性、改良土壤效果和防火性能,火力楠、木荷+台湾相思(伴生树种)混交组合适合在山谷、山脊营造以增强防火性能,火力楠、木荷、福建柏、枫香(主林木)+湿地松以及福建柏、枫香(主林木)+台湾相思可在防火线以内营造。

Collocation Testing of Mixed Species on Ecological Forest Construction in Middle Fujian Coastal Mountain Areas

The study aboat mixed forest of different species collocation in middle Fujian coastal mountain areas was carried out.The results showed that working effect of mixed forest was different because the discrepancy of varied interspecific relation and adaptability.Feasible species of mixed forest were Michelia macclurei,Fokienia hodginsii,Schima superba and Liquidambar formosana as main trees,Pinus Massoniana and Acacia confnas as associated tress.According to soil condition,combined with trees’ adaptability,soil effects and fire resistance,the combined planting of Michelia macclurei,Schima superba and Acacia confnas was suited on the valley or ridgeing resisting the fire perfect.Other species could be planted within the fire line.
