| 摘 要： | 森林的保土功能是其生态功能的重要体现。在对重庆四面山5种林分枯枝落叶层和土壤层保土功能指标定性评价的基础上，通过坐标综合评定法对不同林分保土功能进行综合评价。结果表明:不同林分之间存在明显的功能差异，其中保土综合能力最强的林分类型是杉木 马尾松 木荷针阔混交林（其综合评定值为1.158 1），杉木 马尾松针叶混交林（1.415 2）和石栎 木荷阔叶混交林（1.459 5）差别不大，杉木纯林（2.558 0）保土综合能力最弱，明显弱于其他林分。从排序可看出，树种组成丰富、枯落物储量多的针阔混交林保土能力最强，要优于针叶混交林或阔叶混交林，单一针叶林保土功能最差。

| Abstract: | Soil conservation capacity is one of the important ecological functions of a forest. The soil conservation capacity of several plantations in Simian Mountain of Chongqing City,southwestern China,was evaluated by comprehensive coordinate method based on evaluation of litter and soil layers. Plantations with the lowest score have the best soil conservation capacity. Results showed that different plantations had significant difference about soil conservation capacity. The plantation of Cunninghamia lanceolata-... |
