| 摘 要： | 目的]研究海南3种森林类型的土壤特性及水源涵养功能。方法]以海南岛琼中地区天然次生林、马占相思林和15年生的橡胶林为研究对象,对不同森林类型的土壤理化特性和水源涵养功能进行了研究。结果]不同森林的土壤理化特性及其持水量差异明显,天然次生林和马占相思林土壤容重小、孔隙多、有机质含量丰富、持水量大,而橡胶林土壤容重较大、孔隙少、有机质含量低、持水量低。3种森林类型0~40 cm土层的饱和持水量、毛管持水量从大到小依次为天然次生林、马占相思林、橡胶林。结论]该研究可为海南岛森林生态系统可持续发展提供科学依据。

Soil Properties and Water Conservation Function of Three Forest Types in Hainan Island |
| |
| Abstract: | Objective]To study the soil characteristics and water conservation function of forest types in Hainan Island.Method]The soil properties and water conservation function of three different type forests ( Secondary forest, Acacia mangium forest and Hevea brasiliensis forest) in Hainan Island of Qiongzhong District were studied . Result ] The results showed that existed significant differences in soil properties and water conservation function among three types forest.The secondary forest and Acacia mangium forest had small bulk density, more soil porosity, rich organic matter and large water-holding capacity in soil.But the Hevea brasiliensis forest had large bulk density, fewer soil porosity, low organic matter and low water-holding capacity in soil.The saturation moisture capacity and capillary moisture capacity in soil (0-40 cm) for the three forest types from big to small were secondary forest, Acacia mangium forest, Hevea brasiliensis forest.Conclusion]This study can provide a scientific basis for the sustainable development of Hainan Island forest ecosystem . |
