摘要/Abstract

摘要： 根据野外调查及资料引证，对山西省崖壁植物物种组成、植物区系、生长型、生活习性和资源类型进行统计分析。结果表明：山西省崖壁植物共241种，隶属于53科133属。其中，含10种以上的科有7个，共55属105种，以蔷薇科的种数最多。在种的水平上，中国特有分布和温带分布性质的种共188种，隶属于80属。生长型以多年生草本植物为主，其次为落叶灌木。调查发现，崖壁植物具有生态适应广、耐性强等特点。通过对崖壁植物的驯化培育，可为难造林地的绿化造林提供有价值的种质资源。

Abstract: Based on the field survey and data citation, species composition, flora, growth form, living habits and resource types of cliff plant species in Shanxi Province were analyzed. The results showed that there were 241 species of cliff plants in Shanxi Province, belonging to 53 families and 133 genera. Among them, 7 families, containing more than 10 species, included 55 genera and 105 species; Rosaceae had the most species. At the level of species, 188 species were endemic to China and characteristic of temperate distribution, belonging to 80 genera. Growth form was mainly composed of herbaceous perennials, followed by deciduous shrubs. Our investigation found that cliff plants had the characteristics of wide ecological adaptability and strong tolerance. Domestication and cultivation of cliff plants can provide valuable germplasm resources for afforestation at unsuitable sites.
