| 摘 要： | 运用层次分析法的原理和方法,通过选取影响林地枯落物层和土壤层水源涵养功能的11个指标,对小兴安岭南坡3种主要林型枯枝落叶层和土壤层的水源涵养功能进行定量评价。结果表明:天然杨桦混交林水源涵养综合能力评价值最大(0.427 1),落叶松人工林次之(0.368 7),天然红松林最小(0.204 1),说明天然杨桦混交林水源涵养功能最强,落叶松人工林中等,天然红松林最弱;3种林型的水源涵养功能的强弱与现实生产实际相吻合,表明层次分析法在不同林型水源涵养功能的定量评价上是可行的。

| Abstract: | In this paper,to evaluate the water conservation capacity on the litter layer and soil layer of three main forest types in southern slope of Xiaoxing'anling Mountains,the eleven indices affecting water conservation capacity were selected,and analytic hierarchy process(AHP) method was employed.The results showed that natural poplar and birch mixed forest performed the best water conservation capacity(0.427 1),followed by larch plantation(0.368 7),and natural Korean pine forest was the weakest(0.204 2).The re... |
