沙区碳汇同湿地碳汇、草原碳汇一样,是我国陆地生态系统中最重要的碳库之一。沙区碳汇研究有利于加强环境保护建设、进行防沙固沙工作、提高应对气候变化水平。内蒙古自治区的沙区面积占全国的一半以上,有发展种植碳汇林的广阔空间,因此沙区碳汇的研究将对区内的经济发展和环境保护都具有现实意义。
Sand carbon sinks, like wetland carbon sinks and grassland carbon sinks, are one of the most important carbon pools in terrestrial ecosystems in China. Study on carbon sequestration in sand area is conducive to strengthening environmental protection construction, sandification and sand fixation, and improving the response to climate change. Inner Mongolia Autonomous Region accounts for more than half of the sand area in the country and has broad space for planting carbon sink forests. Therefore, the study on carbon sinks in the sand areas will be of practical significance to the economic development and environmental protection in the region.
