首先通过对克拉玛依及邻近城市现有园林树木的种类、生长状况及其它有关指标现状进行实地调查记录,对克拉玛依土壤剖面调查取样分析,同时收集克拉玛依的自然条件资料并进行补充调查,较系统地掌握了克拉玛依自然条件特点及园林树木种类及生长状况的第一性资料。其次在7 至8 月树木生长旺期,对克拉玛依园林绿地中常用的26 种园林树种进行了部分生理指标的测定,包括:净光合速率、光能利用效率、光饱和点、光补偿点和蒸腾速率、水分利用效率等指标,并对测定结果进行了比较分析。根据以上调查及测定的结果,查阅大量的相关资料,对克拉玛依现有的96 种园林树种(为本次调查的树种数量)的喜光性、水分特性、对土壤养分需求程度、对低温的反应、抗风性等各生理生态指标进行了分析与评价,并做了分类,最后对各项指标进行了综合评价,从而对每一树种的生理生态特性有一个综合的、全面的认识。此外,还从园林树木的树形、叶、花、果、枝干五个方面对克拉玛依园林树种的观赏特性进行了评价。在此基础上对克拉玛依不同类型绿地分别选择适宜的树种。
First, first hand data of feature of natural condition, the kinds and growing states of ornamental treeshas been grasped by investigating and recording, by analysing the soil and by collecting natural data inKelamayi.Second, some physiological characteristics of 26 species mainly ornamental trees have been measured,inculding net photosynthetic rate, light use efficiency, light saturation point for net photosynthetic rate, lightcompensation port for photosynthesis, transpiration rate and water use efficiency,and the comparison andthe analysis have been done in July and August.Analysis, evaluation and classification of physiological and ecological indexes have beendone ,including light characteristics,water characteristics,extent of need to nutrition of soil,lowtemperature characteristics and wind characteristics of 96 species ornamental trees of Kelamayi, based onthe result of the investigation, measurement and looding up a large amount of relative data. And thenworked out the integrate evaluation of the indexes so that can get an integrate and total understanding tophysiological and ecological characteristices of each kind of ornamental trees.Additional, decorative characteristic of ornamental trees of Kelamayi has been evaluated throughappearance, leaf, flowers, fruits,branches of trees.Finally, proteral ornamental trees for different kinds of urban green space of Kelamayi has beenselected.
