焦作市常见地被植物及野生乡土植物资源研究

Research on Common Ground Cover Plants and Native Wild Plants Resource of Jiaozuo City

地被植物在净化空气、降低噪音以及保持水土等方面发挥着重要作用,研究通过调查统计焦作市常见地被植物及野生乡土植物资源,以期为其合理利用和开发提供理论依据。调查结果表明:焦作市常见栽培地被植物共有87种(含种下分类单位),其中,多数为引种栽培种,本地种仅占35.6%。灌木类植物种类几乎与草本地被植物各占一半,但应用频度远大于草本地被植物,用于立体绿化的藤本类地被植物种类较少。初步筛选出豫北太行山区具有较高利用价值的野生乡土地被植物资源90种,包括观花类40种、观叶类23种、观果类11种和观姿类16种,初步分析了其园林绿化价值。另外,多种苔藓植物和蕨类植物也是具有利用潜力的地被植物。

Ground cover plants plays an important role in purifying air ,reducing noise and soil and water conser-vation ,the common ground cover plants and native wild plants of Jiaozuo were investigated ,so as to provide theoretical basis for rational utilization and development .The investigation results showed that there were 87 species of cultivated ground cover plants in Jiaozuo city at present ,and many of them were introduced and culti-vated species .Native species accounted only for 35 .6% .The shrub and herb were about half of the total spe-cies .The application frequency of shrub was higher than herb ,and vine was a few in the city .Ninety species of native wild plants had been selected ,including 40 species of flowering plants ,23 species of foliage plants ,11 species of fruit plants and 16 species of plants with ornamental trunks and branches ,potential ground cover plant resources in Taihang Mountains area in north Henan were analyzed .Moreover ,many species of bryophyte and fern also could be used as ground cover plants .
