“5·12”汶川大地震后,白龙江流域生态环境破坏严重,滑坡、泥石流等山地自然灾害频发,水土流失加剧,生态环境十分脆弱。以甘肃省陇南市武都区段河坝流域为研究区,根据立地条件和植物的生物学特性,遵从生态学原理,研究筛选出适宜当地滑坡体生态修复采用的主要植物29种,其中乔木7种、灌木10种、草本10种、藤本2种,总结出了撒播或条播、水平台造林、鱼鳞坑造林和带状穴植植物篱等4种生态修复技术措施,为当地灾后生态修复与重建提供了理论依据。
After the Wenchuan Earthquake, the ecological environment in Bailongjiang River basin was seriously damaged. Natural disasters such as landslides and debris flows frequently occurred in mountainous areas, soil and water loss intensified and the ecological environment was very fragile. Based on the site conditions and the biological characteristics of plants, the dam of Daba dam in Wudu District of Longnan City of Gansu Province was studied in accordance with ecological principles, and 29 species of plants suitable for ecological restoration of local landslide bodies were screened and identified. Trees 7 10 kinds of shrubs, 10 kinds of herbs and 2 kinds of rattan were summarized. Four kinds of ecological restoration measures were summarized, such as sowing or sowing, watering platform afforestation, fish-scale pit rearing and hedgerow planting for local ecological restoration and reconstruction Provided a theoretical basis.
