鄱阳湖生态经济区植被固碳研究

对鄱阳湖生态经济区的植被固碳研究表明,该区森林碳储量364.3×106 t,草地植被固碳量90.65×104 t,水稻固碳量18.51×106 t,其他农作物固碳量20.64×106 t;鄱阳湖湿地固定CO2量为609 120 t/a。因此,建议对现有森林进行科学抚育与合理采伐,进而形成合理的树种结构、林龄结构与林层结构,提高森林生态系统的稳定性与碳汇能力;运用保护性耕作、灌溉节水和合理施肥技术,培育新型氮素高效利用的农作物新品种,提高光合作用率,从而提高该区农作物的固碳能力;进行合理放牧和草地资源生态监测,严格控制养殖数量和规模,实现草地生态系统减少与固定CO2的重要功能;严禁围湖造田,健全水域环境监测网络,保护湿地生态功能。

Study on Carbon Sequestration of Vegetation in Eco-Economic Zone of Poyang Lake

According to the study on carbon sequestration of vegetation in Eco-economic Zone of Poyang Lake,the total carbon storage of forest is 364.3 x 106(t),the carbon sequestration of grassland vegetation is 90.65 x 104(t),the carbon sequestration of rice is 18.51 x 106(t),the carbon sequestration of other crops is 20.64 x 106(t).The total CO2 storage of wetland is 609120t/a in Poyang Lake.There were some suggestions given,includes: For existing forest,tending wood scientifically and felling reasonably to form ra...
