1) complex storey
复层结构
1.
Experimental study on tree species, disposition, mixed forests (pure forest) in different sites, and fire forest belt with new complex storey or transformed storey with Schima superba.
选择木荷、红花油茶、杨桐等树种，采用随机区组设计和简单机械设计方法，分别进行了不同树种、不同配置、不同立地条件的混交（单层纯林）和复层结构的新建型、改建型防火林带试验研究，结果表明：木荷（杜英）＋红花油茶；木荷（杜英）＋杨桐１：１比例梅花型混交复层结构林带，是较理想的生物防火林带结构模式，具有良好的生长效益、混交效益、立地适应效应，同时还提出了在６种不同条件下较适用的防火林带类型，为今后防火林带体系建设提供了依据。
