黄土高原植被群落演替规律和演替中土壤理化特性变化研究进展

Research Progresses of Vegetation Succession Law and Variation of Soil Physical and Chemical Properties in the Loess Plateau

植被演替是生态学的重要研究内容,也是生物界最常见的自然现象之一,而土壤理化特性是影响植被的主要环境因子之一。由于黄土高原地区生态环境日趋恶劣,该区的植被演替规律和演替过程中土壤理化特性变化的研究一直颇受研究人员关注。本文综述了关于黄土高原植被演替规律和演替中土壤理化特性变化的研究进展,并对其发展做了展望。

Vegetation succession is an important research content of ecology and one of the most common natural phenomena. The soil physical and chemical properties are the main environmental factors affecting the vegetation. Because of the harsh natural environment of the I_oess Plateau, the law of vegetation succession and the variation of soil physical and chemical properties in the succession process have been well concerned by the msearchers. Their progresses were reviewed and their developments were prospected in the paper.
