摘　　要：为深入了解和更好地开发利用湖南云山野生地被植物资源,采用野外调查和查证相结合的方法,运用层次分析法(AHP),对湖南云山野生地被植物资源及其综合评价进行了全面系统的研究与分析。结果表明,云山共有野生地被植物498种,隶属107科254属,其中蕨类植物14科20属30种,双子叶植物80科194属406种,单子叶植物13科40属62种,裸子植物缺乏。生活型以草本类为主,有201种,占总种数的40.36%,而藤本、灌木、蕨类和竹类所占比例较少,分别占总种数的29.52%,23.49%,6.02%和0.60%;其中直立型、缠绕攀援型和蔓生匍匐型地被植物所占比例相差较大,分别占总数的59.84%,29.52%和10.64%,大部分地被植物观赏性高、适应性广、抗逆性强;该区有Ⅰ级地被植物30种,具备良好的地被植物特性,综合评价值最高,是优良的乡土地被植物,可大规模开发利用;Ⅱ级地被植物82种,具备较好的地被植物特性,综合评价值较高,可适度开发利用;Ⅲ级地被植物103种,因个别指标分值相对偏低,可选择性开发利用;Ⅳ级地被植物283种,由于某些指标分值相对较低,只能适当选择,小面积应用。总之,湖南云山野生地被植物资源丰富且大部分具有良好的地被植物特性,在开发利用时应结合工程实际,合理地选择,灵活地运用,以最大限度地发挥其综合效益。In order to fully understand and potentially utilize the wild ground cover plant resources in Yunshan, Hunan,a systemic analysis and evaluation of wild ground cover resources was undertaken.A combination of field investigation and verification methods,and an analytic hierarchy process （AHP）was used.The results show that 498 wild ground cover species were found in Yunshan,belonging to 107 families and 254 genera. These plants include 14 families,20 genera and 30 species of pteridophyte;80 families,194 genera and 406 dicotyledonous species;13 families,40 genera and 62 species of monocotyledonous plants;no gymnosperms were found.Herbs were the dominant vegetation form found in this study,comprising 201 species,40.36% of the total.Lianas,shrubs,ferns and bamboos were also found,accounting for 29.52%,23.49%,6.02% and 0.62% of the total species,respectively.The proportion of erect,creeping and climbing plants differed,ac-counting for 59.84%,29.52% and 10.64% respectively.Most of the wild ground cover plants have good ornamental characteristics,good adaptability and strong resistance.Thirty potentially high （Grade I）value ground cover plants were identified in the study.A further 82 second grade and 103 third grade ground cover species were also identified.The wild ground cover plants resources in Yunshan,Hunan were found to be abundant with many species having excellent ground cover features which could be developed for commercial utilization.
