摘　　要：2008—2009年在我国南方红壤区,研究了3种典型森林恢复方式(自然恢复的天然次生林、人工恢复的本地种马尾松人工林和引进种湿地松人工林)对林地土壤质量的影响.结果表明:天然次生林的土壤含水量、土壤容重、土壤粒径构成、土壤全碳、全氮、全磷、有机碳、速效氮、速效磷、速效钾含量均优于两种人工林.综合土壤物理性状、化学性状和微生物性状得到土壤质量综合指数.天然次生林土壤的综合质量指数(1.20±0.10)显著高于马尾松人工林(0.59±0.03)和湿地松人工林(0.59±0.06),而两种人工林之间差异不显著.在我国南方红壤区,自然恢复的天然次生林土壤质量优于人工恢复的马尾松林和湿地松林.In 2008-2009, an investigation was conducted on the effects of three typical forest resto- ration approaches, i. e. , naturally restored secondary forest, artificially restored native species Pi- nus massoniana plantation （Masson pine plantation）, and introduced species Pinus dliottii planta- tion （slash pine plantation）, on the soil quality in red soil region of Southern China. The results showed that the soil moisture content, bulk density, particle composition, and the contents of total carbon （C）, total nitrogen （N）, total phosphorus （P）, organic C, available N, available P, and available potassium （K） in natural secondary forest were all superior to those in artificial planta- tions. The soil physical, chemical, and microbial properties were integrated into a soil quality index, which was significantly higher （1.20±0.10） in natural secondary forest than in Masson pine plantation （0.59±0.03） and slash pine plantation （0.59±0.06）. Our results suggested as com- pared with the restoration with native species P. massoniana and with introduced P. elliottii, natu- ral restoration could be a better forest restoration approach to improve the soil quality in red soil region of Southern China.
