摘要:

测定了豫西伏牛山区日本落叶松林的林冠截流降雨、土壤渗透速度和地表径流。结果表明,生长期林冠截流降雨185.1mm,截流率为24.4 %,饱和截流量5 mm,截流量随降雨量增加而增加,截流率随降雨量的增加而减少;土壤渗透速度在10mm.min-1左右;地表径流系数在11 %~ 20 %之间;泥沙流失量7.5 × 103 kg·hm-2~ 12×103 kg·hm -2;土壤渗透速度、地表径流量随造林整地方式不同而变化。

关键词: 日本落叶松林, 水文效应, 林冠截流, 地表径流

Abstract:

The forest crown interception precipitation, the penetration speed of soil, and the surface runoff of Larix Kaempferi forests in Funiu Mountain in Western Henan Province were measured in this paper.The results showed that the forest crown interception precipitation during the growth period was 185.1 mm and the rate was 24.4 %.It also indicated that the saturation crow n interception was 5 mm.The crown interception increased with increasing of rainfall, but the crown interception rate decreased with it.The penetration speed of soil was about 10 mm·min-1, the surface runoff coefficient was 11 %~ 20 %, the loss of silt was 7.5 ×103 ~ 12 ×103 kg·hm-2.The penetration speed of soil and the capacity of surface runoff varied with patterns of soil preparation for afforestation.
