摘要: 对浙江庙山坞自然保护区天然次生常绿阔叶林的水文生态特征进行定位样地和径流场观测研 究,以揭示其林内降雨分配规律及林分水土保持功能。结果表明:观测期内(2009年3—10月)林外 总降雨量达1 220.8 mm,乔木层穿透雨量和树干茎流量分别为降雨量的60.2 %和6.0 %,灌木层穿 透雨量为降雨量的53.2 %。林冠截留占总降雨量的40.8 %,其中乔木层截留33.8 %,灌木层截留 7.0 %。林地凋落物层现存量平均为5.31 t/hm2,最大持水率为298 %,最大蓄水潜力为1.58 mm。 观测期内径流场的地表径流1.25 mm,占总降雨量的0.1 %,泥沙总流失量31.99 kg/hm2,庙山坞自 然保护区天然次生常绿阔叶林水土保持效应较好。

Abstract: In order to reveal the precipitation partitioning of forest and the function of soil and water conservation, the ecohydrological characteristics of the natural secondary evergreen broadleave forest in Miaoshanwu Nature Reserve were observed and studied for a short period time of from March to October, 2009 at level of individual stand and runoff plot. The results showed that during the observation period, the total precipitation was 1 220.8 mm. Throughfall under tree layer and stemflow contributed to 60.2 % and 6.0 %, and throughfall under shrub layer contributed to 53.2 % of the total precipitation. Interception loss occupied 40.8 %, including 33.8 % for tree layer and 7.0 % for shrub layer. The litter on forest floor was 5.31 t/hm2, and maximum water retention rate and waterholding capacity of litter were 298 % and 158 mm. The surface runoff from plot was low at only 1.25 mm, which accounted for 0.1 % of the total precipitation; the total sediment was 31.99 kg/hm2, or a soil erosion of 0.262 kg/(hm2·mm); In all, the function of soil and water conservation of natural secondary evergreen broadleave forest was quite good.
