陆地生态系统干扰 - 农田碳收获

我们制作了一个数据集，对 1981 年至 2020 年 40 年间中国作物生产收获的碳进行了全面分析。该数据集的空间分辨率为10x10 km，将耕地分为五种类型，并显示粮食作物在收获总碳中占比最大，为75.9%。过去40年，农田生态系统平均收获碳为0.31 Gt C yr-1。该数据集有望帮助估算耕地生态系统和整个中国的碳收支。这些数据通过开放数据存储库提供，为可持续农业和减缓气候变化的研究和政策制定提供了宝贵的见解。We have created a dataset that conducts a comprehensive analysis of carbon harvested from crop production in China over a 40-year period from 1981 to 2020. This dataset has a spatial resolution of 10x10 km, categorizes arable land into five types, and shows that cereal crops account for the largest proportion of total carbon harvested, at 75.9%. Over the past 40 years, the average carbon harvested in agricultural ecosystems was 0.31 Gt C yr-1. This dataset is expected to aid in estimating the carbon budget of arable ecosystems and of China as a whole. The data are available through open data repositories, providing valuable insights for research and policy-making aimed at sustainable agriculture and mitigating climate change.
