中国分省主要畜种产污系数数据集

为了提升中国分省畜禽产污量估算精度，在系统收集已有文献中各省畜禽产污系数的基础上，基于单位变换、畜禽当量转换、异常值修正、分阶段加权计算以及误差校正等一系列处理，形成了中国分省主要畜禽产污系数数据集。该数据集包含除港澳台外的中国所有省份六种主要畜禽（奶牛、肉牛、猪、蛋鸡、肉鸡和役用牛）的产污系数，可供全国畜禽污染核算、畜禽污染时空分异规律等研究使用。To improve the estimation accuracy of livestock and poultry pollutant production at the provincial level in China, a provincial-level dataset of major livestock and poultry pollutant production coefficients was developed through two core steps: first, systematically collecting the pollutant production coefficients of each province from existing literature; second, conducting a series of standardized processing procedures including unit conversion, livestock equivalent conversion, outlier correction, staged weighted calculation, and error correction. This dataset covers the pollutant production coefficients of six major livestock and poultry species (dairy cows, beef cattle, pigs, laying hens, broilers, and draft cattle) across all provinces in China except Hong Kong, Macao, and Taiwan, and is applicable to research such as national livestock and poultry pollution accounting and investigations into the spatial-temporal differentiation patterns of livestock and poultry pollution.
