母岩母质类型与坡位对湿地松林分生长的影响
|
摘要
对板页岩红壤和四纪红壤2种不同母质土壤和3种不同坡位上的湿地松林分进行调查与分析。结果表明:在四纪红壤与板页岩红壤中生长的湿地松林分其生长量差异显著,说明母质对湿地松林分的生长具有显著影响;位于上坡位的湿地松林分在四纪红壤中的生长表现要显著优于板页岩红壤中的,相反,位于下坡位的湿地松林分在板页岩红壤中的生长表现要显著优于四纪红壤中的。不同母质土壤的湿地松林分受坡位影响程度不同,但生长指标都一致呈现出下坡位>中坡位>上坡位的趋势;四纪红壤中,下坡位林分平均胸径分别高出上坡位、中坡位林分的10.6%和4.0%;板页岩红壤中,下坡位林分平均胸径高出上坡位林分的45.6%,高出中坡位林分的22.2%,差异达极显著(P<0.01)。总体上在不同母质土壤中生长的湿地松林分生长量差异显著,并且板页岩红壤湿地松林分坡位间生长量差异大,四纪红壤湿地松林分坡位间生长量差异较小。
Investigation and analysis of the Pinus elliottii stand growth in two different soil parent materials of plate shale red soil and quaternary red soil with three differentslope position. The result showed that: there was significant difference between quaternary red soil and plate shale red soil in the growth of P. elliottii stand,which shows that soil parent materials have significant effects on the growth of P. elliottii stand. The growth of P. elliottii stand on the plate shale red soil is better than on the quaternary red soil in uphill position, but in lower slope the growth of P. elliottii stand on the quaternary red soil is better than on the plate shale red soil.The influence of different parent material soil on P. elliottii stand is different.However, the growth indicators showed a trend of downhill position > mid-slope position > uphill position. For example, the average DBH of the quaternary red soil P. elliottii stand on the lower slope was 10.6% and 4.0% higher than the uphill position stand and mid-slope position, while the average DBH of the downhill position of the plate shale red soil is 45.6% higher than that of the uphill position stand and 22.2% higher than that of mid-slope position. The difference among different slope position in Pinus elliottii stand is extremely significant(P<0.01). The soil properties of two parent materials directly affected the stand structure of P. elliottii stand directly. The stand structure of P. elliottii distinguish clearly with the slopes on plate shale red soil land.While the P. elliottii stand structure on the quaternary red soil was more consistent.
