金叶莸在北京不同立地条件绿化效果评价

Evaluation of greening effect of Caryopteris×clandonensis ‘Worcester Gold’ in different site conditions in Beijing

对北京地区7种不同立地条件下栽植的金叶莸进行了实地调查,并运用层次分析法建立了综合评价体系,从其适应性、观赏性和景观配置效果3个方面,对不同立地条件下金叶莸的绿化效果进行了综合评价.结果表明:在无遮阴的平地和缓坡地栽植的金叶莸绿化效果最好,遮阴的平地条件下的绿化效果次之,低洼条件下的最差,认为北京地区金叶莸最佳的栽植立地条件为光照充足,无遮阴地段,低洼水湿地段不宜栽植金叶莸.
