摘要
通过对30年生福建柏马尾松混交林、福建柏火力楠混交林与福建柏纯林生长量、林下植被多样性和土壤理化性质的比较分析,进行福建柏不同林分类型生态效益研究。结果表明:福建柏马尾松混交林和福建柏火力楠混交林中福建柏与福建柏纯林相比,树高、胸径和单株材积分别提高了14.6%、13.9%、46.9%和19.2%、11.1%、45.9%,林分总蓄积量增加了70.4%和57.9%,而且生长量和蓄积量的差异达到显著和极显著水平。混交林和纯林植物多样性指数接近。混交林土壤比纯林土壤疏松透气,持水性强,肥力高。
Based on the comparison and analysis of increment, diversity of undergrowth and physical and chemical properties of soil in the Fokienia hodginsii and Pinus massoniana mixed forest, the Fokienia hodginsii and Michelia macelurei mixed forest and the Fokienia hodginsii pure forest, the ecological benefits of different forest types was studied. The results showed that, the height, DBH and in- dividual volume of Fokienia hodginsii in 30-year-old mixed forests increased by 14. 6%, 13.9% ,46.9% and 19.2%, 11.1%, 45.9% compared with the pure forest,the total volume increased by 70. 4% and 57.9% ,and the differences of increment and vol- ume were significant and extreme significant,the plant diversity of mixed forest was similar to pure forest. The soil of mixed forests was looser and ventilating than pure forest, and the water-keeping ability and soil fertility were batter too.
