| 摘 要： | 对 3 2 0国道云南境内从曲靖到大理的旧线公路路域的防护植物作了初步的调查 ,在不同路龄的路线上选择了 2 6个样方 ,统计了其植物的物种多样性 ,并对其中 1 1个样方做了生物量测定。结果初步表明路龄的长短、路域坡度及周围植被状况对路域植被的恢复和植物组成均有影响 ,但哪一种因素起主导作用以及各因素的互作情况仍有待以后进一步的研究。通过分析不同路域植被的物种组成情况和生长状况 ,发现了 1 8种多度比较高、适应性较强的路域广布种 ,它们对公路路域尤边坡的稳定起了重要的作用。在此基础上提出了胡枝子属、野古草属等十几种可用于路域防护的优良植物种类 ,这对人工恢复路域植被、用生物方法保护路域有直接的指导作用 ,并对其它裸地的植被恢复具有借鉴意义。 |

| Abstract: | In order to find useful plant species and use them in vegetation restoration on roadsides,this paper studies and analyzes preliminarily the shelter_vegetation and plants on the roadside along the old highway of National Highway No.320 within the territory of Yunnan Province in Southwest China (from Qujing to Dali).Species Diversity was counted in 26 quadrats selected from different road sections.The biomass were measured in 11 quatrats.The result shows initially that the road_age ,soil characteristics and surrounding plant envionments affect the regeneration and structure of vegetation on the roadsides,but that which factor is the most important is valued to search further.Some plant species with potentials for roadside protection are suggested through analyzing the dominant species and their abundance from different roadsides.This result is also able to be used for vegetation regeneration in bare areas. |
