摘要
以内蒙古中西部山地的白桦(Betula platyphylla)次生林为研究对象,选择了具有代表性的23块样地,对其生境和生长等因子进行了全面调查,在此基础上,应用主成分分析和聚类分析法,将白桦林划分为5种经营类型,根据其特点分别提出了经营林下栽针改造、移植引针改造、封山育林局部抚育、皆伐复壮改造和抚育间伐并结合修枝改造5种经营措施。
A survey on habitat and growth factors was conducted in Betula platyphylla secondary forests in the Midwest of Inner Mongolia by choosing 23 representative sample plots.B.platyphylla forests were classified into five management types by the principal component analysis and cluster analysis.According to their characteristics,five management measures were put forward：transformation by planting coniferous trees,transformation by transplanting and introducing coniferous trees,partial cultivation by closing hillsides to facilitate afforestation,transformation by clear cutting and rejuvenation,and tending and intermediate cutting by pruning.
