摘要
桤柏混交林是紫色土的主要人工混交类型,在长江防护林建设中有重要作用。根据1983年营造的8种混交模式林分,研究了桤柏混交改良土壤、促进柏木生长的效果,用模糊综合评判方法,提出了不同立地类型的混交模式。
Mixed alder and cypress forest is a main mixed type on purple soil,playing an important role in the construction of protection forests in the Changjiang River basin. Researches have been conducted on eight patterns of mixed stand established in 1983 ,focusing on effects of mixed alder and cypress forests in improving the soil and promoting the growth of cypresses . On basis of a fuzzy comprehensive evaluation method,some mixed patterns are suggested for different site types.
