闽南丘陵区长周期桉树人工林综合效益评价

S718.5%S792.39; 运用层次分析法对闽南丘陵区保留密度分别为600、900、1200、1415株·hm-2的15年生桉树人工林综合效益进行评价.以林分蓄积量、出材量、持水量、生物多样性指数、土壤密度、总孔隙度、有机质及速效养分等因子为指标,分别分析了桉树林经济效益、生态效益和地力维持状况,通过综合评判得到长周期桉树林综合效益最高的为保留密度1200株·hm-2的林分,从而为桉树人工林可持续发展提供理论依据....

The analytic hierarchy process was applied to assess comprehensive benefit of 15-year Eucalyptus plantation with four different densities including 600,900,1 200 and 1 415 trees per hechare in the hill area of southern Fujian Province. The economical, ecological, and soil fertility maintenance values for the Eucalyptus plantation with different density were categorized by integrating eight factors involving stand stock, timber output, water holding capacity, biodiversity of underlayer, soil density, total porosity, organic matter and available fertility. The model with best comprehensive value was the tree density of 1 200 trees per hectare for Eucalyptus Plantation according to the assessing, which provided a reference for s
