摘要
以昆明市松华坝水源保护区四种典型的水源涵养林(针叶林、针阔混交林、阔叶林、灌木林地)为研究对象,分别对林冠截留能力、枯落物层持水和截留能力以及土壤水源涵养能力三个方面分析比较。结果表明:四种森林类型中,针阔混交林水源涵养效果最好,灌木林地水源涵养效果最差。
Four types of forests including coniferous forest,mixed broadleaf-conifer forest,broadleaf forest,and shrub land were selected in Kunming Songhuaba Water Resource Protection Area to compare their water conserva-tion capabilities.The capacity of canopy interception,the capacity of litters water-holding,and the capacity of soil water conservation of these four forest types were analyzed.The results showed that mixed broadleaf-conifer forest has the highest water conservation capability.However,shrub land indicates the least capability.
