Marsh vegetation swamp vegetation Growth in the soil is too wet or under water all year round, perennial marsh plants dominant vegetation types. Is a hidden field vegetation. The herbal-based. Floristic composition is more complex, mainly by Cyperaceae, Gramineae, Rosaceae, Asteraceae, Ericaceae such as species composition. Aquatic and terrestrial plants for the transition between types. Most marsh plants have well-developed aerenchyma, roots not in water or wet soil, and water with a leaf stem elongation. Dominant species composition of vegetation by life form can be divided into herbaceous swamps, marshes and woody peat swamp. ① herbaceous swamp. A typical low marsh by surface water or groundwater recharge, Carex and grasses dominate. ② peat bog, also known as the high marsh. By the water supply, nutrient-poor, cold, mainly in the boreal forest, peat moss to become dominant plants, there are a few herbs, low shrubs and trees such as blueberry, larch, etc. ③ woody swamps, marshes, also known as the median. Mix of rain and surface water supplies in the boreal forest zone, forest tundra subzone, tundra with the most widely distributed. Marsh vegetation in the Qinghai-Tibet Plateau in China's Sanjiang Plain in Northeast Ruoergai and more concentrated, herbaceous swamp-based, species composition is relatively simple.

zhaoze zhibei Marsh vegetation swamp vegetation According to the source of water marsh soil, bog can be divided into three types: low marsh, by surface water or groundwater recharge, contain minerals, also known as nutrient-rich swamps; high marsh, the water supply and poor nutrition, also known as oligotrophic swamp; median swamps, rain and surface water from the mixture of supply, also known as swamp in nutrition. (See color pictures Jilin Dehui marsh aquatic vegetation (China), Inner Mongolia Hunshandake aquatic vegetation (China), lakes (Finland), Gannan plateau bog altitude of 3,800 meters (China), Heilongjiang Sanjiang Plain Carex lasiocarpa swamp (China) ) Marsh vegetation types in China, widely distributed, and the northeast of Qinghai-Tibet Plateau Ruoergai Sanjiang Plain is more concentrated, larger. Mainly herbaceous swamp swamp type, followed by woody swamp, bog moss at least. Marsh vegetation species composition is relatively simple. Marshes have important ecological benefits, including peat, plant fiber, forage, etc. have great economic value. (Li, C. □)
