黄土高原生态恢复与重建研究

从黄土高原地区主要生态环境问题出发,综述了该地区生态恢复研究的现状,展示了稳定群落参照标准的选择、物种配置、生态恢复主要措施及其影响因素的不同观点和看法,指出了存在的问题。认为研究应通过建立大尺度的生态水文相互作用过程的模型、利用成熟的物种配置结果开展生态恢复的方案措施、将点上或地块尺度上的研究成果扩展到大流域土地、科学地进行资源利用和生态管理等来恢复生态系统的良性循环,建立这一地区自我维持的、与周围环境相协调的生态安全体系,以此来指导黄土高原生态恢复和重建的实践。

Study on Ecological Restoration and Reconstruction in the Loess Plateau

Aiming at the main issues of ecological environment in the Loess Plateau,the current study achievements of ecological restoration in the area was reviewed.The different opinions of reference standard choice for stable plant community,species allocation,main measures of ecological restoration and its affecting factors were laid out,and in further,the current existing issues were pointed out.And analysis results concluded that the content of ecological restoration and reconstruction study should includes the following items:(1) establish large scale eco-hydrologic interaction model;(2) take fully advantage of well-mastered species allocation technology to study schemes of ecological restoration measures;(3) extend research achievements from small scale experiment plot to large scale basin;(4) return virtuous ecological cycle through scientifically taking use of resources and ecological management;(5) build up self-sustainable ecological security system which could be harmonious to surroundings to guide practice of ecological restoration and reconstruction in the Loess Plateau.
