中国耕地利用环境影响数据集

中国耕地利用环境影响数据集涵盖了2020年中国范围内（港澳台数据暂缺）主要作物生产环境影响栅格数据，所有环境影响指标地图空间分辨率均为5×5弧分（约10×10km）。
中国耕地利用环境影响数据集采用国际普遍关注认可并可量化的4个指标（灌溉用水量、氮肥盈余量、磷肥盈余量以及温室气体排放量）来衡量粮食生产带来的水资源压力、面源污染和气候变化影响。数据全面展示了中国主要农作物生产过程中对各方面环境带来的影响值，有利于从空间格网尺度分析中国粮食生产系统可持续性，有助于支撑绿色农业相关政策的制定与推进，保障中国当前及未来粮食安全。

China Cultivated Land Use Environmental Impact Dataset covers gridded data of environmental impacts from major crop production across mainland China in 2020 (data for Hong Kong, Macau and Taiwan are temporarily unavailable). The spatial resolution of all environmental impact indicator maps is 5×5 arcminutes (approximately 10×10 km).
This dataset employs four internationally recognized and quantifiable indicators: irrigation water consumption, nitrogen fertilizer surplus, phosphorus fertilizer surplus and greenhouse gas emissions, to quantify the water stress, non-point source pollution and climate change impacts caused by grain production. This dataset comprehensively presents the environmental impact values generated during the production of major crops in China across various aspects. It facilitates the analysis of the sustainability of China's grain production system at the spatial grid scale, supports the formulation and advancement of green agriculture-related policies, and safeguards China's current and future food security.
