摘要
为了确切地选择树种,提高混交造林质量,本文从树种相互关系分析入手,提出了混交造林树种选择的新方法。本方法有以下几个前提条件:(1)经过迹地分析,被选择树种基本适生于同一立地条件;(2)根据效益分析,主栽树种已经确定;(3)密度合理,树种间能够相互影响;(4)树种特性已知。
Starting with the analysis on the correlation among tree species, this paper established the criteria for qualitative determination and differentiation of correlation among tree species, and quantified the norms of qualitative determination. Hence the criteria for the selection of tree species for building mixed forest were obtained. These methods are feasible and have guiding significance in practice through practical tests.
