福建含笑杉木混交林幼龄期生产力及生态特性研究

Studies of the Productivity and Ecological Characteristics of the Mixed Forest of Michelia fujianensis and Cunninghamia lanceolata at Its Young Stage

为开发利用优良珍稀阔叶树资源、增加造林树种生物多样性及防治人工林地力衰退 ,对福建含笑纯林及福建含笑×杉木混交林进行造林试验 ,研究了福建含笑杉木混交林幼龄期的林分生产力、小气候特征以及土壤改良效果与机制 .结果表明 ,福建含笑杉木混交林林分生物量和生产力较高 ,具有调节林分小气候、改善土壤环境状况、充分利用营养空间、提高土壤微生物数量及土壤酶活性等生态特性 ,从而促进林木的生长 ,是一种较好的混交组合 ,值得推广应用 .

The pure Michelia fujianensis forest and the mixed forest of Michelia fajianensis and Cunninghamia lanceolata were afforested at a test level. The results show that the stand biomass and the productivity of the mixed forest are relatively high, and the mixed forest has such features as regulating the stand microclimate, improving the soil environment status, utilizing nutritive space fully and increasing the microbial number of the soil and the soil enzyme activities. Therefore, it promotes the forest tree growth. The mixed forest is a nice mixed combination; it should be applied and popularized in the future.
