在广泛调查常绿阔叶林标准样地的基础上,又对样地的土壤类型土壤养分进行了初步分析。结果表明:主要土壤类型有红壤、山地红壤、山地黄壤、山地黄红壤和山地草甸土。土壤全磷的含量,18年生、34年生和65年生分别为0.217%、0.099%、0.109%和每百克干土分别含速效磷0.74、0.53、0.44毫克当量。与马尾松林、杉木林相比,常绿阔叶林地土壤有机质、全氮、全磷、水解性氮、速效磷、速效钾和代换盐基总量7项指标均高于杉木林和马尾松林,以马尾松林最差。土壤养分随海拔高度上升其含量有下降的趋势。
On the basis of extensive investigation of standard sample plots of evergreen broad-leaved forest, the soil nutrients in the sample plots were also analyzed. The results showed that the main soil types were red soil, red soil from mountain, yellow soil from mountain, red soil from mountain and meadow soil. The content of total phosphorus in soil was 0.217%, 0.099% and 0.109% respectively at 18th, 34th and 65th years, and available phosphorus 0.74,0.53,0 per 100 grams dry soil respectively. 44 mg equivalent. Compared with Pinus massoniana forest and Cunninghamia lanceolata plantation, the contents of soil organic matter, total nitrogen, total phosphorus, hydrolyzable nitrogen, available phosphorus, available potassium and substituted salt in the evergreen broad-leaved forest were higher than those in Chinese fir and Pinus massoniana forest, Masson pine is the worst. Soil nutrients with the altitude increased its content has a downward trend.
