The photosynthetic and water characters of 19 representative garden trees were measured by using the Li-6200 photometer in Urumqi. The text took the 19 tree species as example and evaluate the ecological characters of tree species, and studied the arrangement mode of tree species, combining structure theory of ecological community with the ecological characters of tree species, then analyzed tree selection, the intraspecific and interspecific relationship, the tree arrangement mode in courtyard greenland, the science reference for arranging garden plants in Urumqi.
Landscape Tree Information System apply VB6&Access2000 to set up the background database and proscenium searching system, uses Photoshop and Photoedit to edit image, use software engineering to develop Landscape Tree Information System and establishes a friendly and beautiful user interface and abundant database.
园林树木信息系统(LTIS, Landscape Tree Information System)以Access2000开发后台数据库以VB6开发前台界面,采用PHOTOSHOP、PHOTOEDIT等图形图像工具编辑图片,采用件软件工程的原理进行系统开发,建立了友好美观的人机交互界面和信息丰富的数据库。
From the analyses, the conclusions were drawn out that: 1) Net photosynthetic rate, photosynthetic radiation-use efficiency, transpiration rate and water use efficiency were determined and queued up for guiding the choice and arrangement of landscape trees.
No clear climatic trend was found in the foliar Δ13C values of common garden trees.
Gene frequencies were investigated in the α-Est1 locus between Japanese populations of Panonychus citri occurring on some fruit trees and on the garden trees, Osmanthus trees and Ilex crenata.
It infests Osmanthus species, which are evergreen roadside and garden trees.
For the countermeasure areas, cultivation of non-edible crops such as garden trees, flowers, and fiber crops; landreformation; and heavy application of finered earth (up to 30 cm) were strongly recommended.
However, small patches of vegetation-cover, such as roadside trees and garden trees, are excluded from the land-use data.
