We compiled a nationwide dataset of carbon dioxide (CO ) efflux from 1405 measurements, and found that lakes, reservoirs, and rivers emit a total of 61.9 ± 55.3 TgC as CO each year, corresponding to ~6.3% of the annual total national CO emission in 2020. Our analysis showed that the presence of anthropogenic disturbances in catchments strongly influences the emission of CO from these waters in the non-pristine areas, masking the catchment productivity effect on the emission of CO . Our results highlight the need for adjusting climate change models for taking into account anthropogenic effects on CO emissions from inland waters.
我们汇编了一个全国范围内的二氧化碳（CO ）排放数据集，其中包含 1405 项测量结果，发现湖泊、水库和河流每年总共排放 61.9±55.3TgC 的 CO ，相当于 2020 年全国 CO 年排放总量的~6.3%。我们的分析表明，集水区人为干扰的存在强烈影响了这些非原始水域中 CO 的排放，掩盖了集水区生产力对 CO 排放的影响。我们的研究结果突出表明，需要调整气候变化模型，以考虑内陆水域中人为因素对 CO 排放的影响。
