| 摘 要：对于鼎湖山的马尾松林、针同混交林、季风常绿阔叶林等三种植被类型，普遍认为，其演替是依次由低级向高级发展的过程。但是，通过对鼎湖山这三种植物群落的土壤结构厦某些水文效应分析表明：① 土壤中含有粒径小于0.001 mm粘粒的量，季风常绿阔叶林>马尾松林>针阔混交林；②土壤中含有粒级大于0.25 mm土壤团聚体的量，季风常绿阔叶林>马尾松林>针阔混交林；③ 土壤吸持水分能力、土壤的抗侵蚀能力等水文效应与土壤中粒径小于0.001 mm 粘粒、粒级大于0.25 mm 土壤团聚体的量呈正相关，表现为季风常绿阔叶林最好，针阔混交林最差。可见，三种植物群落的土壤结构厦某些水文效应与其演替过程并不完全一致。 |

| 摘 要(英文)：In general view，the succession processe of three plant communities in Dinghushan is from lower to higher stage，that is to say，from coniferous forest，mixed forest to monsoon evergreen broad—leaf forest．This paper analyzed soil structure and hydrological effects of these communities．The results showed that：①The content of grain dlameter<0.001mm clay in soil is monsoon evergreen broad—leaf forest> coniferous forest>mixed forest．②The content of grade> 0.25 mm group in soil is monsoon evergreen broad—leaf forest> coniferous forest>mixed forest．③Some of the hydrological effects including the capacities of water retention，resistance erosion and so on are bound up with the content of graln diameter< 0.001mm clay and grade> 0.25mm group in soil．The monsoon evergreen broad—leaf forest is the best and the mixed forest is the worst．So the conclusion is that the soll structure and its characteristics of hydrological effects are not completely consistent with their successlon processes for three plant communities． |
