摘　　要：生态节约型园林是风景园林的未来发展方向,是城市园林绿化健康发展的必由之路。苗木是园林工程的重要物质基础,其优劣状况直接影响着园林工程的质量。在介绍工程苗木质量评价意义的基础上,从生态节约的角度出发,重点剖析了苗木的品种、规格、树形、根系4大因子对园林生态功能和工程经济成本的影响,并在此基础上构建了基于AHP分析法的生态节约型园林工程苗木质量评价体系,并应用该方法对福建省龙岩石锣鼓公园园林工程苗木质量进行了评价.结果表明:石锣鼓公园32种苗木的评价分数符合正弦曲线,I级苗木有3种,分别为红榕、朴树与枫杨,它们是石锣鼓公园的基调树种;Ⅱ级、Ⅲ级苗木可占总苗木种数的74.99%,红花风铃木、无忧树等归化树种生长势一般,是否能够适应龙岩市种植,仍需要进一步观察实验;IV级的黄花槐、大花紫薇,它们均是著名的观赏树种,但是在石锣鼓公园未表现出应有的景观效果;V级为3种,垂柳、樱花、银杏表现出生长势不良,有濒临死亡的迹象。该方法为工程设计、施工监理、苗木采购、标准制定等提供参考和借鉴。Eco-saving type landscape garden will be the direction for future development for landscape architecture, which is the only way to healthy development of urban garden greening. Seedlings makes up the important material foundation in landscape engineering, whose status will exert immediate influence on quality of landscape engineering. On the basis of the significance of evaluation engineering seedling quality, from the perspective of ecological conservation, the impacts of the four factors composed of the seedling varieties, speciifcations, tree, the root on landscape ecological function and engineering economic costs were analyzed. Then, the method of ecological landscape architecture engineering seedling quality evaluation system by using AHP analysis method was constructed, and the engineering seedling quality of Longyan Shiluogu garden, Fujian province was evaluated based on the analysis data. The results show that the scores of 32 seedlings conformed to the sine curve, and the there were 3 I-grade seedling, they are red rongping, hackberry and Chinese beech, these were the keynote tree species in this park; The II-grade and III-grade seedlings accounted for 74.99 % of the total tree species, the naturalized species such as safflower wind Suzuki, worry-free tree and so on grew with general growth potential, whether can the three tree species adapt to plant in Longyan city still needs further experimental observation; The IV-grade of seedlings, yellowflowers, big beautiful crape myrtle tree, they are both famous ornamental tree species, but they showed no proper landscape effects; The V-grade seedlings, including weeping willow, cherry blossoms, blossom ginkgo, showed poor growth situation and signs of dying. As a result, this method can provide some references for engineering design, construction supervision, nursery stock purchase and standard setting.
