| 摘 要： | 采用野外调查与室内分析测定相结合的方法，对珠江上游典型小流域7种立地类型植被、枯落物的持水能力及土壤蓄水能力进行研究。结果表明，不同立地类型的水源涵养能力差异显著，乔木林和梯田具有更好的水源涵养能力。7种立地类型的总蓄水量依次为云南松次生林（5478．46t／hm^2）、杉木次生林（5360．25t／hm^2）、云南松-桉树林（5356．73t／hm^2）、梯田（5351．00t／hm^2）、农坡地（4932．00t／hm^2）、荒草地（4713．58t／hm^2）、灌木林（4679．87t／hm^2），云南松次生林的总蓄水量分别高于杉木次生林、云南松-桉树林、梯田、农坡地、荒草地、灌木林2．21％、2．27％、2．38％、11．08％、16．23％、17．06％。 |

| Abstract: | The study on water-holding capacity of standing vegetation, litter and water storage capacity of soil in seven land types in the Typical Small Watershed of Upper Reaches of Pearl River was conducted by filed work and laboratory analysis and testing. The results showed that there were significant differences in water conservation function among land types. The forests and the terrace had greater water conservation function than other land types. As for the total water storage capacity, the greatest water storage capacity of the seven land types was the secondary forest of Pinus yunnanensis （5 478.46 t/hm^2） which was 2.21%, 2.27%, 2.38%, 11.08%, 16.23% and 17.06% higher than the secondary forest of Cunninghmia lanceolata （5 360.25 t/hm^2） , mixed stand of Pinus yunnanensis and Eucalyptus （5 356.73 t/hm^2） , terrace （5 351.00 t/hm^2） , slope farm land （4 932.00 t/hm^2） , grassland （4 713.58 t/hm^2） and shrubbery （4 679.87 t/hm^2） respectively. |
