广西森林水文研究是在广西中亚热带的桂东北龙胜里骆林区、南亚热带的桂东南岑溪七坪林场、桂中的宜山庆远林场、桂西的田林老山林场进行的。研究的林型有:杉木人工林、常绿阔叶林、常绿与落叶阔叶混交林、马尾松林、柠檬桉与马尾松混交林。其地貌有中山、低山、丘陵和台地。每一种林型都在林内、林外建起400m~2的径流场,用三角溢流堰和水位计测定地面径流量。同时,在林内、外设置气象观测场,观测林内、外降雨量和林冠截留雨量、树干茎流
Guangxi forest hydrology research is carried out in the Luanlin district of Longshengli in Guangxi northeast subtropical Guangxi, Qixian Qipin forestry center in southeastern Guangxi, Qingyuan forest farm in Yishan of Guizhong, and Tianlin Laoshan forest farm in Guangxi. The forest types studied include: Chinese fir plantation, evergreen broad-leaved forest, evergreen and deciduous broad-leaved mixed forest, Pinus massoniana forest, Eucalyptus citriodate and Pinus massoniana mixed forest. The landscape has Zhongshan, low mountains, hills and terraces. Each kind of forest type is in the forest, and a runoff field of 400m ~ 2 is built outside the forest. The ground runoff is measured by a triangular overflow weir and a water level gauge. At the same time, meteorological observatories were set up inside and outside the forest to observe the rainfall inside and outside the forest,
