[Effects of simulated nitrogen and sulfur deposition on litter decomposition rate in an evergreen broad-leaved forest in the Rainy Area of Western China.].

To examine the effects of nitrogen and sulfur deposition on litter decomposition rate, a one-year field experiment was conducted with the litter bag method from April 2013 to April 2014 in an evergreen broad-leaved forest in the Rainy Area of Western China. There were nine treatments with three nitrogen levels and three sulfur levels, including control (CK), low nitrogen deposition (LN, 50 kg N·hm·a), high nitrogen deposition (HN, 150 kg N·hm·a), low sulfur deposition (LS, 200 kg S·hm·a), high sulfur deposition (HS, 400 kg S·hm·a), low nitrogen and low sulfur deposition (LNLS), high nitrogen and low sulfur deposition (HSLS), low nitrogen and high sulfur deposition (LNHS), and high nitrogen and high sulfur deposition (HNHS). The results showed that the leaf litter residual rate ranged from 57.

[Effects of simulated nitrogen deposition on soil microbial biomass carbon and nitrogen in natural evergreen broad-leaved forest in the Rainy Area of West China].

To understand the effects of increasing nitrogen deposition on soil microbial biomass carbon (MBC) and nitrogen(MBN), an in situ experiment was conducted in a natural evergreen broad-leaved forest in Ya'an City, Sichuan Province. Four levels of nitrogen deposition were set: i.e.

[Characteristics of carbon stock in artificial forest ecosystem in Sichuan Province of China].

By using forest inventory data in combination with plot measurement, the characteristics of carbon density, stock, and partitioning in artificial forest ecosystem in Sichuan Province of China were studied. The results showed that the carbon density in this forest ecosystem was averagely 161.16 Mg C x hm(-2), being ranked in the order of soil layer (141.

[Spatiotemporal variation of carbon storage in forest vegetation in Sichuan Province].

Based on the modeling of forest biomass and timber volume and the 1974-2004 forest inventory data, the spatiotemporal variation of carbon density and storage in forest vegetation in Sichuan Province was studied. The results showed that the forest carbon storage was increased from 300.02 Tg in 1974 to 469.
