昆明市三个主要广场园林植物绿量研究(英文)

Quantity of plant leaf area on three major public squares in Kunming City, China

通过对昆明市区三个主要广场上30种园林植物的调查测定,建立了其中13种园林植物绿量计算的回归方程,直接测算出另外17种园林植物的绿量,并分别得出三个广场园林植物的总绿量。研究结果表明,乔、灌、草结合的胜利广场的绿地率和单位面积绿量均为三个广场之最,这种多层次立体栽培模式既有利于提高单位面积的绿量,也有利于植物群落生态效益和景观效益的充分发挥。在综合分析三个广场园林植物绿量特点的基础上,认为设计合理的复层结构、良好的抚育管理可以有效提高人工植物群落的单位面积绿量并据此提出相关建议。表3参7。

Regressive formulae to calculate the quantity of plant leaf area for 13 species of ornamental plants were set up based on investigation data of 30 species on 3 major public squares (Dongfeng square, Shengli square and Guandu square) in Kun-ming City, China, which were applied to calculate quantities of plant leaf area of these 13 species. The quantities of plant leaf area for the other 17 ornamental plant species on these squares were directly measured, and the total quantity of plant leaf area of each studied square was obtained individually. The results showed that the quantity of plant leaf area on Shengli square with ornamental plants structure composed of arbor tree species, shrub tree species and turf grass was highest among the three squares. It is believed that the design model of multi-storied vertical structure and proper tending of plant community could not only increase the quantity of plant leaf area, but also play an important role in generating ecological and landscaping benefits. Some corresponding suggestions were put forward on the basis of comprehensive analyses on the plant leaf area quantity of the three representative squares in Kunming urban area.
