| 摘 要： | 基于连续10年的观测，本文对比研究了3种植被类型的地表径流效应，证明了混交林的水文效益无论从哪方面都较桉树林和裸地明显，并且随着年度的的推移，混交林的水文效益更加突出。发生产流的最小降雨量条件为：混交林30.2mm，桉树林5.1mm，裸地6.0mm。产流发生时饱和上层厚度分别为12.6mm，3.4mm，和6.3mm。理论上，作者阐明了3种植被类型下的产流类型，提出了桉树林下地表更易形成击实层这样一个设想，这就为水土保持林的营造提供了一个极富实际意义的例子，为在海岸台地这样一个特殊生境下综合研究水土保持效益提供了资料。

| Abstract: | Based on the consecutive measurement (1981～1990), we studied the surface run off in three types of vegetation. The results show that the hydrological profit of the mixed forest was far higher, by every means, than those of the Eucalypt forest and the Naked land. Furthermore, the profit was more and more evident with time. The minimum rainfall of initiating surface runoff was 30.2mm in the mixed forest, 5.1mm in the Eucalypt forest and 6.0mm in the naked land. The depth of saturated soil was 12.6cm, 3. 4cm and 6.3cm, respectively. Theoretically, the authors demonstrated the ways in which surface runoff generates in the three types of vegetation and proposed that the land of the Eucalypt forest is more susceptible to forming the surface crusting because of the bigger rain drop going through the Eucalypt canopy. All above provide a very meaningful result for water and soil conservation, and thus bridge the gap of research on the multiple profit of forest in water and soil protection for coastal land. |
