• Context Coarse woody debris (CWD, ≥10 cm in diameter) is an important structural and functional component of forests. There are few studies that have estimated the mass and carbon (C) and nitrogen (N) stocks of CWD in subtropical forests. Evergreen broad-leaved forests are distributed widely in subtropical zones in China. • Aims This study aimed to evaluate the pools of mass, C and N in...
Storm runoff, which has some special characteristics such as random, abrupt and changing largely in water quality, is difficult to be treated by conventional wastewater treatment. Constructed wetlands has advantages including low operation cost, simple in process, strong resistance to shock loading. The performance of an experimental constructed wetland system was simulated and monitored in Southern...
The purple soil in hilly area in southern China is experiencing severe erosion. Understanding the effects of forest management approaches on soil quality is very important during the vegetation restoration. Three replicated plots of four forest stands with different forest restoration approaches, including natural secondary forest, plantations of Robur tree plantation (Lithocrpus glabra) (RTP), sweetgum...
A dated surface sediment core and surface sediment samples from the Pearl River Estuary (PRE) were analyzed for the spatial distribution and the temporal evolution of light stable isotope (C, N, and S) signals, besides organic contaminants (PAHs, DDTs, HCHs and PCBs). The sediment core was recovered from about 6.5m water depth and was deposited with a sedimentation rate of about 4.5mm/a. The stable...
