枫香人工造林初期效果分析

研究了不同立地质量等级、不同坡向、不同坡位对7年生枫香混交林生长的影响,结果表明:Ⅱ级立地枫香的生长明显好于Ⅲ、Ⅳ级地;不同坡位、坡向对枫香的生长有显著影响,枫香的生长量大小依次是下坡>中坡>上坡,阴坡>半阴坡>阳坡;枫香适宜与杉木、马尾松混交,混交林生长量均大于杉木、马尾松纯林生长量。

Effect Analysis of Liquidambr formosana Hance Afforestation at the Early Stage

The effects of different site quality grades,different aspects,and different slopes on the growth of 7-year-old Liquidambr formosana Hance mixed forest were studied.The results showed that: Liquidambr formosana Hance atⅡ-level site grew better than those at Ⅲ,Ⅳ-level sites;different slope positions,aspect had significant impact on the growth of Liquidambr formosana Hance,the amount of the order of the growth of Liquidambr formosana Hance: down slope>middle slope>upper slope,shady slope>semi-shady slope>sunny slope;Liquidambr formosana Hance was appropriate to mix with Cunninghamia lanceolata and Pinus massoniana,the mixed forest growth amount was larger than Cunninghamia lanceolata or Pinus assoniana pure forest growth amount.
