    摘要:在大量野外调查和驯化试验的基础上,采用层次分析法对华南地区140种野生观赏地被植物进行综合评价。综合评价模型由引种难易、生长状况、抗逆性与观赏效果4个评价准则及相关的12个评价因子构成。结果表明:薏苡、山蒟、粽叶狗尾草、千里光等综合得分在4以上的30种植物易于驯化,具较高观赏价值,可作为重点开发利用对象,2~4分者可适度开发,低于2分者暂不推荐开发。此外,进一步探讨了优良种类在不同绿地中的应用形式及特殊种类的引种栽培要点,展望野生地被植物的应用前景及驯化引种要点。研究结果可为华南地区野生地被植物开发应用提供科学参考。

    Abstract:Based on extensive field investigation and domestication experiment, 140 wild groundcover species were synthetically assessed by analytical hierarchy process (AHP). The assessment model is made up of 4 evaluation criteria that is introduction adaptability, growth state, stress resistance and ornamental effect, along with 12 related evaluation factors. Results demonstrate that 30 wild species with an overall score larger than 4 such as Coix lacryma-jobi, Piper hancei, Thysanolaena latifolia and Senecio scandens have greater decorative effect with less difficulty in domestication, those with a score between 2-4 can be selectively developed and species scored lower than 2 are not recommended. Moreover, we further probe into how to use these excellent species in different green spaces and the essentials in introducing and cultivating species that need special care, alongside the important points in introducing wild groundcover plants and the application prospect of them. The results will provide a scientific reference for using wild groundcover plants in South China.
