摘 要:在阐明STRATUM模型的研究思路及研究方法的基础上,选用该模型中与昆明市区相近气候区相应树种综合效益计算的参数数据,采用典型抽样调查对昆明市区悬铃木等16个主要行道树树种群体的经营管理效益成本之比进行了计算和比较分析研究,并针对这些主要行道树树种的选择应用及其经营管理现状加以评价,从而提出优化方案和完善建议。On the basis of elaborating the research methodology of STRATUM model developed by DAVIS Center for Urban Forest Research, Forest Service, USDA, benefit-cost ratios of tending and management of Plantanus sp. and other 15 major species applied as street trees in Kunming urban area were calculated and analyzed through typical sampling investigation and by means of applying the corresponding database set for each tree species in zones with similar climatic conditions as Kunming. Some countermeasures and suggestions were proposed in the light of evaluation on the species selection and the present status of tending and management for these street trees to optimize the tending scheme and improve the management.
