- 摘要:
- 以宜昌市区和三峡坝区的边坡为调查对象，采用典型取样法，共调查边坡51处，样方192个，统计了边坡的基本情况，对边坡绿化效果进行了评价，对边坡绿化植物的物种数量特征、结构组成和配置模式进行了分析。结果表明：被调查区域边坡绿化整体效果较好，评价等级达到好和较好的占到了总数的60.7%；该地区的常见边坡植物有40种，包括草本23种，藤本7种，灌木10种；草本植物中外来种占到了50%；草本层和灌木层的多样性水平明显高于藤本层；该地区的边坡绿化植物配置模式主要有3种：草坪（草花）型、藤-灌型、灌-草型，其中灌-草型应用得最多。最后，探讨了目前边坡生态防护存在的问题并提出解决对策。
- Abstract:
- The slopes in the three gorges dam and Yichang city were taken as the investigation objects，and the typical sampling method was used.The number of investigated slopes was 51；the number of samples was 192.The statistics about the basic situations of these slopes were made，the slope greening effects were evaluated，the species quantity characteristics，structure，composition and configuration mode of slope greening plants were analyzed.The results indicated that the slope greening effect was fairly good overall in the surveyed area，and the very good and fairly good evaluation levels accounted for 60.7% of all surveyed slopes；there were 40 species of common slope plants in this area，and they included 23 species of herbs，7 species of lianas，10 species of shrubs；the exotic species accounted for 50% in herbs；the levels of diversity of the herb layer and shrub layer were obviously higher than the liana layer′s；there mainly were three kinds slope greening plant configuration mode in this area,herb type，liana-shrub type，shrub-herb type；and the shrub-herb type was most used.At last，the problems existing in the ecological slope protection were discussed and the countermeasures were put forward.
