The water contents in 1m soil layer of eight vegetation types in Yuanmou dry and hot valley in rainy season(August 2 to September 2) were measured and analyzed.These eight vegetation types are Pinus caribaea plantation,Pinus caribaea+Dodonaea viscosa plantation,Albizzia kalkora natural regeneration forest;Dodonaea viscosa+Tephrosia candida plantation,eucalyptus plantation,grassland,waste land and expansive soil.

通过对元谋干热河谷区加勒比松人工林、加勒比松+车桑子人工混交林、山合欢天然更新林、车桑子+山毛豆人工混交林、桉树人工林、草地、荒坡、膨胀土8种植被类型林地1 m土层内不同层次雨季(8月2日~9月2日)土壤水分含量的分析研究得出：在雨季8种植被类型林地土壤的水分含量均较低，因其土壤的物理性能较差，故蓄水保水能力也较差；各植被类型林地土壤的有机质、养分含量均极低，按照土壤养分含量分级标准，各植被类型林地土壤的养分含量均在6级以下。
