永安市巨尾桉人工林生长的区位效应初步研究
Study on Effect of Topography of Eucalyptus grandis × E.urophylla Plantations in Yong’an City
【摘要】 依据调查样地资料,分别对永安市巨尾桉人工林在不同小地形、不同坡位和不同坡向上的生长进行了研究,结果表明:山脊和山坡的林分生长量相差不大;山洼林分生长最好,其次为山脊和山坡,山顶林分生长最差;不同年龄、不同坡向的林分中,不同坡位的生长差异不大;巨尾桉在阳坡上生长明显优于半阴半阳坡的林分。
【Abstract】 Based on the field investigation in industrial raw material forest of E.grandis × E.urophylla in Yong’an city,growth status in different topography,slope site and slope direction were studied.Stands on the valley grew best,then the one on the slope and ridge,and worst the one on the top.The influence of slope site on growth of different type of stands was slight.Stands on east or west slope grew worse than those on southern slope.
