摘要
通过对设于山东抱犊崮自然保护区3种森林植被类型下6块测试样地的土壤理化性状进行分析比较,结果表明：侧柏林下土壤容重、黏粒组成、田间持水量等指标均小于杂木林和刺槐林;而刺槐林下土壤水热条件较好,土壤有机质、氮、磷等养分含量相对较高。另外,侧柏林下土壤呈酸性,而杂木林和刺槐林下土壤呈碱性。
Soil physi-chemical characters of six sampling area under three types of forest vegetation in Baodugu Nature Reserve in Shandong are analysed and compared, the results shows that： the soil bulk density, clay particle content, field capacity under Platycladus orientalis are less than that under the Secondary Forest and Robinia pseudoacacia. Besides, the soil water/ thermal elements, soil organic matter, N and P content are higher. Besides, the soil under the Platycladus orientalis Plantation Forests partial to acidity while the soil under the Secondary Forest and Robinia pseudoacacia partial to alkalescence.
