In 2008-2009, an investigation was conducted on the effects of three typical forest restoration approaches, i. e., naturally restored secondary forest, artificially restored native species Pinus massoniana plantation (Masson pine plantation), and introduced species Pinus elliottii plantation (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 plantations. 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 compared with the restoration with native species P. massoniana and with introduced P. elliottii, natural restoration could be a better forest restoration approach to improve the soil quality in red soil region of Southern China.
2008 - 2009年，对三种典型森林恢复方式，即天然恢复的次生林、人工恢复的乡土树种马尾松人工林和引种树种湿地松人工林，在中国南方红壤地区土壤质量方面的影响进行了调查。结果表明，天然次生林中的土壤含水量、容重、颗粒组成以及总碳（C）、总氮（N）、总磷（P）、有机碳、速效氮、速效磷和速效钾（K）含量均优于人工林。将土壤物理、化学和微生物性质综合纳入土壤质量指数，天然次生林的该指数（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）。我们的结果表明，与乡土树种马尾松和引种树种湿地松的恢复相比，天然恢复可能是改善中国南方红壤地区土壤质量的更好的森林恢复方式。
