文山自然保护区土壤现状与保护

通过对文山自然保护区土壤现状的调查，以及对其土壤形成条件、土壤类型特征及分布规律的研究，将其划分为淋溶土纲，铁铝土纲，初育土纲3个土纲，暗棕壤、棕壤、黄棕壤、红壤、黄壤和石灰土6个土类，暗棕壤、棕壤、黄棕壤、红壤、黄红壤、黄壤、红色石灰土和黑色石灰土8个亚类，并对保护区土壤生态的脆弱性及其对生物多样性的影响进行了探讨，提出了保护对策和措施。

Present Status and Conservation of Soils in Wenshan Nature Reserve

By surveying the soil types and their distribution, and their forming condition in Wenshan Nature Reserve,the authers divided the soils into 3 orders (Alfisolf,Ferralsol and Inceptisol), 6 groups (Dark-brown earths, brown earths,Yellow-brown earths, Red earths, Yellow earths and Limestone soils) and 8 subgroups (Dark-brown earths, brown earths, Yellow-brown earths, Red earths,Yellowish red earths,Yellow earths, Terra rossa and Rendzina). The soil ecological fragility and its impact on biodiversity were studied and the countermeasures and the strategies of protection were put forward.
