问题 问答题 简答题

试述居住区植物配植的原则?

答案

参考答案:

1、乔灌结合,常绿植物和落叶植物、速生植物和慢生植物相结合,适当地配植和点缀花卉草坪。

2、植物种类不宜繁多,但也要避免单调,更不能配臵雷同,要达到多样统一。

3、在统一的基调的基础上,树种力求变化,创造出优美的林冠线和林缘线,打破建筑群体的单调和呆板感;

4、在栽植上,除了需要行列栽植外,一般都要避免等距离的栽植,可采用孤植、对植、丛植等,适当运用对景、框景等造园手法,装饰性绿地和开放性绿地相结合创造出丰富的绿地景观;

5、在栽植设计中,充分利用植物的观赏特性,进行色彩的组合与协调,通过植物叶、花、果实、枝条和干皮等显示的色彩,在一年四季中的变化为依据来布臵植物,创造季相景观。
