中文摘要	以高密市林业局苗圃内进行区域适宜性研究表现良好的5年生9个杨树无性系为研究对象,从耗水特性方面,对9个杨树无形系生长的区域适宜性进行了综合评价。结果表明:不同杨树无性系的生长量和耗水特性指标差异较大,在α=0.01水平上都存在显著性差异,L35、I-107胸径、树高、单株材积的生长量较大,明显高于其它杨树无性系。对单株材积、单株耗水量、耗水速率和蒸腾速率4个指标的综合评价结果表明,在高密市应选择生长迅速、耗水量大的L35、I-107在供水充足的沙壤土栽植;选择生长较快、耗水量小的T26在天然降水条件的沙壤土栽植;选择生长较慢、耗水量中等的NL895、NL80106、中林2025在需水关键时期进行灌溉的沙壤土栽植。
英文摘要	Nine superior 5-year-old poplar clones,selected from the nursery garden of the Forestry Bureau of Gaomi City,were used to study the suitable sites for poplar growth based on water consumption characteristics. Results showed that there were significant differences in growth increment and water consumption characteristics for different poplar clones. The increments in diameter at breast height,tree height and individual tree volume of clones L35 and Ⅰ-107 were significantly higher than those of other poplar clones. Comprehensive evaluation on individual tree volume,water consumption of a single tree,water consumption rate and transpiration rate shows that the fast-growing clones of L35 and Ⅰ-107 with large water consumption should be planted in sandy soil in Gaomi City where there is sufficient water stored in the soil; the faster-growing clone T26 with low water consumption should be planted in sandy soil at high rainfall conditions; the slow-growing clones with moderate water consumption,such as NL895,NL80106 and zhonglin 2025,should be planted in sandy soil where irrigation is available during the most critical period for water requirement.
