摘要
干旱区河岸植被对保护种质资源、稳定河岸、调节微气候和美化环境、提供人类活动场所均有重要的潜在和现实价值。研究认为河道断流,自然环境的脆弱,人类活动对植被的直接和间接破坏导致干旱区河岸植被退化。进行植被重建、应急输水、自然恢复过程中减少人类干扰是恢复退化植被的主要方法。本文以生态学和水文学为基本理论框架,利用3S技术和评价模型,研究纵向、横向、垂直与时间4维的大尺度河岸植被稳定与河岸生态系统稳定及关系,提出退化植被恢复技术。
Riparian vegetation has a potential and practical significance to the protection of resources of species,river bank fixation, climate regulation and environmental beautification, and it also can provide humans niceliving sites in arid region. Study results showed that dry river, fragile natural environment and human activitiesdamaged the vegetation directly or indirectly which led to the degradation of riparian vegetation in arid region.The emergency water supply, reducing human interference in the process of vegetation, and rebuilding naturalrecovery are the main methods to recover vegetation. Based on ecology and hydrology theoretical framework, weput forward a recovery method on riparian vegetation using 3S technology and evaluation model to study thelarge-scale riparian vegetation structure stability and riparian ecosystem stable condition and relationship at 4dimensions such as lengthways, crosswise, verticality and time.
