通过集水区6年定位观测并对毛竹林、杉木林的森林水文基本特征进行对比观测和分析,基本结论是:在丘陵山地森林覆被率70％～80％的条件下,比同等条件的空旷地降水量多26.1mm,而林地蒸发量则比空旷地小;杉木林内降水量比毛竹林大,截留量和茎流量比毛竹林小;地表径流量及泥沙流失量采伐迹地>杉木林>毛竹林;林地贮水量毛竹林>杉木林>采伐迹地;林地土壤水分渗透速度毛竹林>杉木林地。
Based on the 6-year positioning observation of the catchments and the comparison and analysis of the basic forest hydrology features of Moso bamboo forest and Cunninghamia lanceolata forest, the basic conclusion is that under the condition of 70% ~ 80% forest cover in hilly and mountainous area, The amount of precipitation in the open area was 26.1mm, while the evaporation in the forestland was smaller than that in the open area. Precipitation in the fir forest was larger than that in the bamboo forest, and the interception and stemflow were smaller than that in the Phyllostachys pubescens forest. > Moso bamboo forest; woodland water storage Moso bamboo> Cunninghamia lanceolata> deforestation; forest soil water infiltration rate Moso bamboo forest> Cunninghamia lanceolata forest.
