论水土保持措施的碳汇效应若干问题
Issues of carbon sink effect of soil and water conservation measures
全球CO2 浓度的持续升高是引起全球气候变暖的重要因素,在这种大背景下,局部地区的水资源短缺也将成为新常态。水土保持改变地表覆被和结构、土地利用方式和陆地生态系统的经营措施等,可以增加植被和土壤碳库的碳储存能力。本文综述了林草措施恢复对植被碳库的影响,并探讨了植被恢复、梯田、淤地坝和免耕等措施与土壤碳库的关系,认为水土保持措施具有明显的碳汇效应,可以缓解气候变化的不利影响。研究可为区域高质量发展和实现"碳中和"提供有效支撑。
The continuous elevation of global CO2 concentration have an important effect on global warming.Concurrently,water shortage may be intensified in many areas of the world.Soil and water conservation measures can increase the carbon storage capacity of vegetation and soil carbon pool by changing the land cover and structure,land use pattern and management measures of terrestrial ecosystem.In this paper,the effects of vegetation restoration on vegetation carbon pool were reviewed,and the relationship between vegetation restoration,terraces,silting dam and no-tillage and soil carbon pool were discussed.It was concluded that soil and water conservation measures had obvious carbon sink effect and may alleviate the adverse effects of climate change.The research can provide effective support for regional high-quality development and the realization of"carbon neutrality".
