豫南山区不同群落类型近地表层持水特性
Water-holding properties of the near surface layer of different communities types in mountains of south Henan province, China
摘要
Abstract
In order to analyze the water-holding capacity and different characters of different communities in different growth stages in near surface layer, the study choose 50 typical plots of different communities of different growth stages in south of Henan mountain area to mensurate and analyze the related water-holding capacity of ahoveground grass and litters of water conservation in near surface layer. Results showed that the biomass of aboveground that had the high significant positive correlation(P＜0.01) with water holding capacity declined as the age increased. The interception ability of the grass's trend was: Grass＞ Shrub＞ Coniferous forest(20 a) ＞ Coniferous forest(40 a)＞ Mixed conifer and broad-leaved forest (20 a) ＞ Mixed conifer and broad-leaved forest (30 a)＞ Broad-leaved forest(10 a) ＞Mixed conifer and broad-leaved forest (50 a) ＞broad-leaved forest (20 a)＞ Broad-leaved forest (30 a);The maximum water-holding capacity and available interception ability had significant correlation with standing crop of the litter.Maximum water-holding capacity of the litter for the comprehensive trend was: Broad-leaved forest (20 a)＞ Broad-leaved forest (30 a)＞ Mixed conifer and broad-leaved forest (30 a)＞ Mixed conifer and broad-leaved forest (20 a)＞ Mixed conifer and broad-leaved forest (50 a)＞Coniferous forest (20 a)＞ Broad-leaved forest (10 a)＞ Coniferous forest ( 45 a)＞Grass. The comprehensive trend of gross water holding capacity of near surface layer in this area was: Shrub ＞Coniferous forest ＞Broad-leaved forest＞Mixed conifer and broad-leaved forest＞Grass, which showed that the better protection measures should be given to under storey vegetation of arbor forest to have a better soil and water conservation effect.关键词
