辽东山区人工红松林降雨截留分配效应

以辽东山区人工红松林为对象,在大气降雨基础上观测林间穿透雨、树干流特征,结果表明:2016年本溪大气降雨47场,降雨总量677.7 mm,平均每场为14.4 mm,单次最大降雨量为75.4 mm,最小为1.1 mm;8月份降雨量最大,为205.8 mm,占总量30.3%;10月降雨量最小,为7.0 mm,占总量1.01%。人工红松林林间穿透雨量为504.4 mm,占大气降雨总量74.43%;树干流水量为173.3 mm,占大气降雨总量25.57%,林分减少了降雨对地表面的侵蚀和水土流失。

The rainfall retention distribution effect of artificial Pinus koraiensis forest in Liaodong mountain area

The woodland penetrating rain and tree trunk stream characteristics were observed on the basis of atmosphere rainfall by taking artificial Pinus koraiensis forest in Liaodong mountain area as object.The result showed that there were 47 atmosphere rainfall in Benxi in 2016.The total rainfall amount was 677.7 mm.The average amount was 14.4 mm.The once maximum rainfall was 75.4 mm.The minimum was 1.1mm.The maximum rainfall amount occurred in August was 205.8 mm which accounted 30.3 % of total.The minimum rainfall amount occurred in October was 7.0 mm which accounted 1.01 % of total.The woodland penetrating rain amount of artificial Pinus koraiensis forest was 504.4 mm which accounted 74.43 % of total atmosphere rainfall.Tree trunk stream of water was 173.3 mm which which accounted 25.57 % of total atmosphere rainfall.The stand decreased the erosion and water and soil loss of rainfall on the earth's surface.
