福建柏木荷混交林生长及生态效益研究

Fokienia hodginsii and Schima superba Mixing Efficiency Analysis

对福建柏木荷混交林、福建柏纯林中的福建柏生长量、林分物种多样性及林地土壤理化性质进行对比研究,结果表明,33年生的福建柏木荷插花混交林与福建柏纯林相比,福建柏胸径、单株材积分别增加20.6%、53.2%,林分总蓄积量增加34.9%,差异达显著水平;植物种类和数量增多,土壤更加疏松透气,养分含量也更高。

This paper comparatively studied the Fokienia hodginsii growth amount,species diversity and soil physical and chemical properties of Fokienia hodginsii pure forest and Schima superba mixed forests,the results showed that 33-year-old Fokienia hodginsii and Fokienia hodginsii flowers mixed forest Fokienia hodginsii DBH and individual volume of Fokienia hodginsii and Schima superba mixed forests increased by 20.6% and 53.2% respectively as compared with Fokienia hodginsii pure forest,the stand total volume increased by 34.9%,reached the significantly difference;plant species and populations increased;the soil was more loose and breathable,soil nutrient content was also higher.
