摘要:
 对北京地区各类绿地中现有景天属（Sedum）植物资源进行调查。结果表明，各类绿地中栽培的景天属植物有12种（变种）及19个品种；园林绿化中应用频度较高的为八宝景天（S. spectabile）、佛甲草（S. lineare）、景天三七（S. aizoon）和垂盆草（S. sarmentosum）4种；根据观赏特征可分为观叶、观茎、观姿株、观花果4类；主要园林应用方式有花坛花境、园林地被、屋顶绿化和盆栽观赏；园林应用中存在乡土资源开发少、引进种类保护力度弱、应用种类单调、模式单一以及栽培养护管理不到位等问题。最后对北京园林绿化中景天属植物的引种、保护、应用和养护提出建议。
Abstract:
Sedum resources in Beijing were investigated. In different green spaces, 12 species and 19 varieties were found. Those with high application frequency in green spaces were S. spectabile, S. lineare, S. aizoon and S. sarmentosum. According to the morphological types and ornamental values, Sedum could be classified into 4 categories, including foliage, stem, plant-type, flower and fruit ornamental features. The main landscape applications were flower beds and borders, ground covers, roof greenings and potted ornamentals. There were some problems in landscape applications, such as inadequate exploitation of local resources, weak conservation of introduced species, unitary species and patterns and management issues. Some suggestions concerning to the introduction, protection, species selection and application of sedums in Beijing were put forward.
