摘要
以淄博市城市周围破坏山体为研究对象,根据野外调查结合植被恢复的影响程度分析,选定破坏山体外貌形态、坡度、边坡高度、土层厚度和砾石含量5个立地因子,并对之进行分级量化;利用聚类分析法将破坏山体划分为7个立地条件类型和16个亚型;不同立地条件类型植被恢复难易程度不同,在分析各立地条件类型特征的基础上,因地制宜地提出不同的植被恢复措施。研究成果可为破坏山体的植被恢复提供科学依据。
The breakage hill pits around Zibo City was regarded as the research object of the paper. Based on the field investigation combined determined including morphology, with the influence degree of vegetation restoration, five site factors were slope height, slope degree, soil thickness and gravel content, and then were classified and quantified. The breakage hill pits was divided into seven site types and sixteen subtypes with the method of Cluster analysis. The difficult degree of vegetation restoration was different for site types On the basis of analyzing site types characteristic, vegetation restoration measures were put forward properly to provide the scientific basis for vegetation restoration of the breakage hill pits.
