Abstract: Types and characteristics of wetland soil were briefly introduced, and ecological functions of soil in wetland ecosystem were also discussed in this paper. Wetland soils can be divided into five types, including histosol, gleysol, halomorphic soil, paddy soil and underwater soil, containing higher organic matter and situated in intense reduction circumstance. Because of their special physical and chemical properties, wetland soils showed varied ecological functions such as (a) to be as a medium of wetland living things ;(b) to provide nutrients; (c) to release greenhouse gases and (d) to purify or absorb toxic substances in wetland ecosystem.

Key words: high temperature and humidity stress, spring soybean, seed vigor, germination, anatomical structure, pre-harvest seed deterioration resistance.
