摘要：对广东南岭小坑自然保护区5种林型(常绿阔叶林、针阔混交林、毛竹林、马尾松林、杉木林)土壤肥力主要指标进行了分析测定,采用因子分析方法对各林型土壤肥力状况进行了比较。结果表明:常绿阔叶林的土壤有机质质量分数((5.83±0.34)%)、土壤全N质量分数((0.369±0.019)%)较其他林型高,且林型间存在显著差异(P<0.001)。不同林型的土壤碳氮比不同,其中马尾松林地最高(24.69±6.01),常绿阔叶林最低(15.77±1.59)。各林型间土壤全P质量分数、土壤速效K质量分数均存在显著差异(P<0.001),且均是以毛竹林林地质量分数(P,(0.045±0.001)%;K,(79.00±4.03)mg/kg)最高,表明毛竹林比较适合本地生长,对地力维持有一定作用,可以适当发展。除常绿阔叶林和毛竹林外,其余3种林型土壤均表现出明显的P缺乏,当地在林业经营措施中可适当施加P肥以提高地力。5种林型综合排序为常绿阔叶林(0.576)>毛竹林(0.481)>针阔混交林(0.196)>马尾松林(-0.558)>杉木林(-0.694),说明地带性森林类型常绿阔叶林是当地最佳的林地利用方式。
An investigation of soil nutrients status was conducted in five forest stands in Nanling mountains, northern Guangdong Province, including evergreen broadleaved forest, coniferous and broadleaved mixed forest, moso bamboo plantation, Chinese red pine plantation, and Chinese fir plantation. The factor analysis method was applied to the quantitative evaluation of soil nutrient status of the five forest stands. Result showed that the contents of soil organic matter and total nitrogen in the evergreen broadleaved forest were higher than those of other forests, indicating a significant difference at a 0.001 level. The highest contents of organic matter and total nitrogen were found in the evergreen broadleaved forest, which were （5.83 ±0.34） percent and （0.369 ± 0.019） percent, respectively. The C/N ratio varied with different forest types, and the highest value （24.69 ± 6.01 ） percent was found in Chinese red pine forest and the lowest （ 15.77 ± 1.59） percent in the evergreen broadleaved forest. Extremely significant differences in contents of total phosphorus and soluble potassium were found in different forest types, and the highest values were in the moso bamboo stand, namely （0.045±0.001） percent and （79.00 ±4.03）mg/kg, respectively. Result indicates that moso bamboo plantation is relatively suitable for reforestation in the study area to maintain forest productivity. Application of phosphorus fertilization to the plantation could be a desirable management measure due to the distinct deficiency of phosphorus in the forest stands except for the evergreen broadleaved forest and the moso bamboo plantation. The result of factor analysis showed that the value of integrated nutrient index for the evergreen broadleaved forest （0. 576 ） was the highest, and then followed by moso bamboo plantation （0. 481 ）, coniferous and broadleaved mixed forest （0.196）, Chinese red pine plantation （ -0.558）, and Chinese fir plantation （-0.694）, indicating that evergreen broadleaved forest is the best forest type for local afforestation.
