Yield degraded grassland area has more than doubled
"Water Conservation in the Upper Yangtze River wetlands Ruoergai grasslands, lush plants, has been reproduced gull Cheung Hok dance." Yesterday, the reporter was informed by the provincial Science and Technology Department to implement the "Eleventh Five-Year" National Key Technology Program "Research Zoige Wetland Restoration and demonstration "for Zoige Wetland desertification increased, vegetation is severely degraded, biological disasters, ecological functions of wetlands degradation and other issues, has successfully established a plateau wetland ecosystem restoration and protection of integrated technology system, will be degraded grassland areas of Yield Improvement more than doubled, sandy grassland vegetation cover 50% or more, for the degradation of wetlands provides important ecological management of technical support.
Wetland flowers into Block 1 Weather Stations
Overgrazing, mouse pest outbreak, climate change, drainage ditch leading to degradation of Ruoergai grassland desertification in recent decades the most important reason, of which over-grazing is the most important. In 2007, Sichuan's "two sessions", the deputies put forward on the development of "Wetland Protection Regulations of Sichuan Province," the motion by the "two sessions" on behalf of members of the broad response. Provincial government also issued a "decision on building an ecological province," clearly required by 2010, deterioration of the ecological environment has been effectively curbed. This has also allowed the western region of Sichuan to become the first province started building an ecological province.
Provincial Science and Technology Department official says, "Zoige wetland restoration technology research and demonstration" project since the Sichuan University, Beijing Normal University, Sichuan Grassland Research Institute, Lanzhou University, Ruoergai National Authority, outside the province rely on wetland protection units of the joint efforts of the multidisciplinary, industry, academia, and research proposed by combining the "plateau wetland ecosystem restoration and protection of integrated technology systems", that is, the wetland ecological water security and water, degradation of wetland ecosystem restoration, sandy grassland restoration of degraded grassland ecosystem restoration and other technical patterns. Wetland in the flower into Block 1 of meteorological stations, dynamic record pressure, temperature, humidity, wind direction, wind speed, rainfall and other weather changes in values, determination of the different vegetation types and use patterns, wetland peat, greenhouse gas emissions, absorption and fixed effect.
Sandy grassland vegetation cover more than 50%
Alpine wetland and sand for the ecological recovery of the lack of forage species, experts and scholars were selected from local plants to the degradation of wetland vegetation, desertification, a variety of suitable grassland plants, which ABA rod Zhongbin grass, oats and Phalaris grass Aba ecological management has been the national grass seed grass seed registration and seed breeding and established a technical system, also studied at the Wang was born in waterside grass wet ripening stage, germination conditions, the first time applied to wetland management .
Provincial Science and Technology Department of Social Development, said at Pei Wei Zheng, for different degrees of degradation of wetlands, the project team has established 10 demonstration areas and a seed breeding base, with a total area of 2850 ha, meadow vegetation cover is 100% , the degraded grassland areas of grass production more than doubled, sandy grassland vegetation coverage reaches over 50%. In Ruoergai flowers around the lake, after the flowers Lake area, the red of the original Japanese dry Joe Moon Bay wetlands and Longriba wetlands, radiation to promote alpine wetland ecosystem restoration technology 5000 hectares, to effectively improve the radiation zone of the vegetation cover of 20% above.

Chinese and foreign experts Ruoergai prairie known as the "kidney of the plateau in western China", "China's most beautiful wetlands prairie," is one of six prairie, the largest highland peat swamp is an important source of water in the Yellow River. Ruoergai County is located in the northeast edge of Qinghai-Tibet Plateau, Aba Prefecture in Sichuan Province, northwest and northern provinces of Sichuan northern gate leading to the Northwest. Ruoergai Zoige Wetland Nature Reserve is located in County, is China's largest area of peat swamp centralized distribution. The main object of protection for the alpine wetland ecosystem and black-necked cranes and other rare animals. The protection zone is not only the key areas of biological diversity and the world alpine region with one of the most abundant species, or important water conservation area. Source: Huaxi Dushi Bao
