陕北西阳湾植被恢复的特点初探

A Preliminary Study on Features of Vegetation Restoration on Xiyang River Bend in North Shaanxi

分析了西阳湾地区主要植物群落类型的种类组成、空间结构、物种多样性、生物量及土壤特性。结果表明 ,该区的植被恢复经历了禾草草原群落阶段、半灌木草原群落阶段、灌丛草原群落阶段 ,最终将到达顶极群落——疏林草原群落。在植被恢复过程中 。

Number of individuals and species, diversity indices, Shannon Wiener diversity index, biomass and soil fertility of the main plant community types in Xiyang River Bend region were analysed. It was found that the vegetation restoration in this region went through poion steppe community stage, semi shrub steppe community stage, shrub steppe community stage and reached the climax community-open wood steppe community stage. Plant community and habitat are interdependent in the process of vegetation restoration, that is the essential motive power of succession.
