摘要：为了解不同经营方式对林地理化性质的影响,对哈尔滨市丹清河林场近自然经营、传统经营和未经营3种方式下的天然次生针叶林土壤物理和化学性质进行了研究。结果表明:1)近自然经营一定程度上影响了天然次生针叶林的土壤物理性状,但这种干扰远小于传统经营;2)不同经营方式间土壤有机质、全N质量分数与贮量没有明显差异,全P质量分数及贮量以近自然经营最大,经营强度最大的传统经营林分土壤中全K质量分数和贮量最大;3)经营方式对速效N和有效P没有明显影响,但近自然经营林分的交换性K离子质量分数和贮量最大;4)近自然经营林分土壤C/N比降低、pH值升高,为土壤微生物活动提供了较好的生活环境,有利于土壤肥力的增强和长期生产力的提高。
An investigation on three natural secondary coniferous forests under close-to-nature management, traditional manage- ment and non-management in Danqinghe forest farm of Harbin was conducted to analyze the influence of different forest management mode on physieoehemieal properties of soil. The results show that the close-to-nature management can influ- ence the physieoehemieal properties of soil to a certain degree, but this disturbing is less than the traditional management. There is no significant difference for total C and total N in soil among different management modes, and the largest content and the storage of total P and total K are in the close-to-nature management and traditional management forest, respective- ly. There is no influence of management modes on available N and effective P, while the content and the storage of ex- changeable K in soil are the largest in close-to-nature management forest. The decrease of soil C/N ratio and the increase of pH in the close-to-nature management forest provide a better living condition for soil microorganisms and develop the soil fertility and long-term production.
