[Carbon sequestration characteristics and regional differences of typical warm and tropical grasslands in Henan Province, China.].

In this study, we examined the vegetation and soil carbon density characteristics and carbon distribution differences of four typical grasslands in two climatic zones, including warm-tempe-rate tussock (WT), warm-temperate shrub tussock (WS), tropical tussock (TT), and tropical shrub tussock (TS) in Henan Province. The results showed that the average aboveground biomass of grasslands was significantly higher in Northwest Henan (327.4 g·m) than that in South Henan (221.
