摘要
对黄土高原景观生态学特征的分析表明:黄土高原景观在空间上具有明显的分带性,显著的黄土垂直节理特征,独特的坡面景观结构、微地貌景观以及农业景观,呈现以景观带为基质,斑、廊、缘为点缀的复杂景观镶嵌格局;在时间上存在明显的季节景观变化和地质时间尺度景观变化,沟蚀系统的发展决定了其地貌景观的基本骨架和发展方向.黄土高原的生态恢复要遵从景观生态学原理,科学理解黄土高原生态恢复的涵义,合理选择林草恢复措施等.
The landscape ecological characteristics of the Loess Plateau of China were analyzed by using the landscape ecology. The results showed that the landscape of the Loess Plateau spatially appeared apparent zonation and loess vertical joint characteristics, distinctive slope structure, micro-landform and agricultural landscape which had a mosaic structure with patches, corridors, edges and matrixes based on the landform difference, climatic difference, vegetation difference, soil difference etc. Chronologically, the landscape of the Loess Plateau obviously showed seasonal and geological changes. Thus, the eco-restoration of the Loess Plateau was processed by use of the theory of landscape ecology. The signification of eco-reconstruction must be scientifically apprehended and some reasonable measurements of restoring woods and grasses selected.
