摘要:
以凤凰县4年生马尾松混交林为研究对象,于轻度、中度、重度石漠化区的混交林中分别随机设置标准样地,研究石漠化程度对马尾松幼林生长的影响。结果表明:马尾松幼龄林的平均树高和胸径随着石漠化程度的加深而逐渐降低。在中度石漠化区的马尾松幼龄林平均树高比轻度石漠化区的降低8.71%,重度石漠化区的比轻度石漠化区的降低27.55%;在中度石漠化区的平均胸径比轻度石漠化区的降低22.87%,重度石漠化区的比轻度石漠化区的降低43.25%。轻度石漠化区、中度石漠化区以及重度石漠化区间胸径差异均达极显着。轻度石漠化区与中度石漠化区以及中度石漠化区与重度石漠化区的树高差异不显着,轻度石漠化区与重度石漠化区的树高差异极显着。
Abstract:
Taking 4yearold Pinus massoniana mixed forest in Fenghuang County as the research object, and randomly set standard samplein the mild, moderate, severe rocky desertification area of mixed forests, to study the effect of rocky desertification degree of sapling forest growth in PMassoniana.The results show that the average tree height and DBH of PMassoniana sapling forest as the degree of rocky desertification were gradually reduce the average height in moderate rocky desertification area and severe rocky desertification area of PMassoniana sapling forest is lower than slight rocky desertification 8.71% and 27.55% respectively.The average DBH in moderate rocky desertification and rocky desertification area is lower than slight rocky desertification area 22.87% and 43.25% respectively.Slight, moderate and severe rocky desertification interval up to extremely significant difference were observed in DBH.There is no significant different in the height between slight and moderaterocky desertification, or moderateand and severe rocky desertification, and significant different in the height between slight and rocky desertification.
