摘要
全球大气氮沉降急剧增加对内陆水生态系统产生不良影响。中国是全球三大氮沉降热点地区之一,为了充分了解氮沉降对中国内陆水体的影响,制定合理的水污染治理方案,需要清楚地量化内陆水体的氮沉降通量。为此,本文利用LMDZ-OR-INCA模型结合内陆水体面积数据,获得了近三十年中国内陆水体氮沉降数据集,为进一步了解中国内陆水体氮沉降的时空格局及其影响机制奠定了基础。同时,我们公开共享该数据集(https://ecodb.scidb.cn/detail?dataSetId=892431070195089408),并提供在线访问和下载服务。
Dramatic increases in global atmospheric N deposition have had adverse effects on inland water ecosystems.China is one of the three hot spots of N deposition in the world.In order to fully understand the impact of N deposition on inland waters in China and formulate a reasonable water pollution treatment plan,we need to clearly quantify the N deposition flux in inland water.Therefore,using the LMDZ-OR-INCA model combined with inland water area data,we obtained the dataset of inland water N deposition in China from the 1990s to the 2010s,which lays a foundation for further understanding the spatial-temporal pattern of inland water N deposition and its impact mechanisms.At the same time,we publicly share this dataset and provide online access and download services at https://ecodb.scidb.cn/detail?dataSetId=892431070195089408.
