| 摘 要： | 采用野外测定与室内实验分析相结合的方法,对高黎贡山南段4种典型植被类型枯落物层持水性能进行对比研究。研究结果表明,(1)枯落物总厚度为天然阔叶林>旱冬瓜林>杉木人工林>次生阔叶林,其中未分解层枯落物厚度为旱冬瓜林>天然阔叶林>杉木人工林>次生阔叶林,半分解层枯落物厚度为天然阔叶林>杉木人工林>旱冬瓜林>次生阔叶林;枯落物总贮量为天然阔叶林>次生阔叶林>旱冬瓜林>杉木人工林,其中未分解层枯落物贮量为次生阔叶林>天然阔叶林>杉木人工林>旱冬瓜林,半分解层枯落物贮量为天然阔叶林>旱冬瓜林>次生阔叶林>杉木人工林;(2)未分解层及半分解层最大持水量均为天然阔叶林>杉木人工林>旱冬瓜林>次生阔叶林;(3)未分解层及半分解层持水速度均为天然阔叶林>杉木人工林>旱冬瓜林>次生阔叶林。因此,4种植被类型枯落物层持水性能以天然阔叶林为最好。 |

| Abstract: | The water holding capacities of litters of four typical vegetations in south section of Gaoligongshan mountain were studied through field determination,indoor experiments and analysis.The study results were as follows: 1) The thickness of litter was in the order of natural broadleaved forest >Alnus nepalensis forest >Cunninghamia lanceolata plantation > secondary broadleaved forest;among which,the thickness of undecomposed litter was in the order of Alnus nepalensis forest > natural broadleaved forest >Cunninghamia lanceolata plantation > secondary broadleaved forest;the thickness of semi-decomposed litter was in the order of natural broadleaved forest >Cunninghamia lanceolata plantation >Alnus nepalensis forest > secondary broadleaved forest.The total storage of litter was in the order of natural broadleaved forest > secondary broadleaved forest >Alnus nepalensis forest >Cunninghamia lanceolata plantation,among which,the storage of undecomposed litter was in the order of secondary broadleaved forest > natural broadleaved forest >Cunninghamia lanceolata plantation > Alnus nepalensis forest,the storage of semi-decomposed litter was in the order of natural broadleaved forest >Alnus nepalensis forest > secondary broadleaved forest >Cunninghamia lanceolata plantation.2) The maximum water holding capacity of undecomposed litter and semi-decomposed litter was in the order of natural broadleaved forest >Cunninghamia lanceolata plantation >Alnus nepalensis forest > secondary broadleaved forest.3) The speed of water holding of undecomposed litter and semi-decomposed litter was in the order of natural broadleaved forest >Cunninghamia lanceolata plantation >Alnus nepalensis forest > secondary broadleaved forest.In conclusion,the water holding capacity of natural broadleaved forest was the best among these four vegetations. |
