最近,到几个绿化较好的住宅小区去参观。一方面体验到小区开发者对绿化树的充分重视,注意了乔、灌、草的合理优化配置,一度出现的“重草轻树”现象已有所扭转,“小树林”取代了“大草坪”;另一方面也感到还存在许多不足之处,其中比较突出的问题是尚未全面发挥绿化树的多种功能。树木作为小区绿化的主体,有以下几种功能要充分发挥:(一)生态功能。采用大片草坪尽管能使小区在短期内见绿,但遍植生长虽然较慢的高大乔木、下铺硬质地面或小面积草坪的绿化形式却更能符合生态和人与自然亲近的需要。 Recently, to a few greening better residential area to visit. On the one hand, we experienced the full attention of residential developers to the greening trees, paid attention to the rational and optimal allocation of trees, shrubs and grasses, and once the phenomenon of “heavy grass and light trees” has been reversed, the “grove” has been replaced “Big lawn ”; on the other hand also felt that there are still many shortcomings, the more prominent problem is not yet fully play a variety of green tree functions. Trees as the main green area, there are several functions to give full play to: (a) ecological function. Although large-scale lawn can make the district see the green in a short time, the greening form of the tall tree, the lower hard ground or the small area lawn which grows slowly is more in line with the need of the ecology and the closeness between man and nature.
