摘要:
采用样地、样方调查等方法,以黑松纯林为对照,研究了包括对照在内的9种临沂市云蒙湖湖区周边主要人工水源涵养林林枯枝落叶层和土壤的持水能力,结果为9种林分枯落物层自然含水率、饱和持水率分别为6.34%~23.27%和114.92%~318.23%,最大拦蓄率、最大拦蓄量分别为108.58%~294.96%和2.12~9.63 t·hm-2,有效拦蓄率、有效拦蓄量分别为91.34%~247.23%和1.78~8.08 t·hm-2,这4个指标侧柏×刺槐林都最高,黑松×侧柏林都最低,差异显著(P<0.05); 土壤贮水量为206.11~685.32 t·hm-2,白蜡×山杏林土壤持水能力最强,垂柳×刺槐林土壤持水能力最差,差异显著(P<0.05),从枯落物持水能力和土壤持水特性综合来看,核桃×板栗混交林地持水能力最好,应优先选择。
Abstract:
Quadrat and sampling plot were applied to investigate into the water holding capacity by soil and litter in different forests surrounding Yunmeng lake of Linyi city, with Pinus thunbergii Parl forest as CK.The result showed that natural water content and saturated water holding capacity in litter of nine forest stands have ranging from 6.34%~23.27% and 114.92%~318.23%.Maximum retaining rate and maximum retaining content are respectively 108.58%~294.96% and 2.12~9.63 t·hm-2 and effective retaining rate and effective retaining content are 91.34%~247.23% and 1.78~8.08 t·hm-2, with highest performance in forest of Robinia pseudoacacia and Platycladus orientalis and poorest performance in forest of Pinus thunbergii and Platycladus orientalis.Water storage of soil ranges from 206.11~685.32 t·hm-2, highest in forest of Fraxinus chinese and Prunus armeniaca and lowest in forest of Salix babyloncia and Robinia pseudoacacia(P<0.05).Integrating water holding capacity of litter and soil, forest of Juglans regia and Castanea mollissima is of highest performance.
