摘　　要：对元谋干热河谷封禁9年区域内山合欢天然林地、加勒比松人工林地相关水文侵蚀效应进行了研究,得出了一系列有关在雨季中末期林地土壤水分动态变化、树干流量与林内雨量以及截流率、林地枯落物含水量、林地径流量、滴溅侵蚀效应等变化规律。The hydrology and erosion effect rules of Albizia kalkora wild woodland and Pinus caribaea artificial woodland in dryhot valley are researched, including the change rule of soil water content in woodland during midend rainy season, runoff on trunk and rainfall in woodland, the ratio of keeping rainwater, the water content of withering branches and leaves on woodland, runoff on woodland and rainwater striking erosion rule. 
