2015-2030年中国各省用水紧张度多情景数据

在5种未来情景下（SSP1、SSP2、SSP3、SSP4、SSP5）利用水文水资源模型（ECHO）模拟未来用水紧张度。用水紧张度等于人类活动总用水量与总的可利用水量比值。总用水量包括农业灌溉用水、工业用水、生活用水和生态环境用水。农业灌溉用水（agricultural）利用蒸散发模型（SWAT内置Penman-Monteith）法。工业用水（industrial）的方法包括定额法、趋势法。定额法的公式：Wi=V*Ki；Wi为工业需水量，V为工业产值（万元），Ki为每万元产值需水量。生活用水（Domestic）选用定额算法，按人均用水乘以人口密度和计算生活用水量。生态环境用水（Eco-environment）选用蒸散发模型（SWAT内置Penman-Monteith）法，模拟生态环境用水量。总的可利用水量等于降水产生的径流量。

Future water stress was simulated using the hydrological and water resources model (ECHO) under five Shared Socioeconomic Pathway (SSP) scenarios (SSP1, SSP2, SSP3, SSP4, SSP5). Water stress is defined as the ratio of total human water consumption to total available water resources. Total human water consumption includes water for agricultural irrigation, industrial use, domestic use, and eco-environmental use. Water for agricultural irrigation is calculated using the evapotranspiration method based on the Penman-Monteith equation implemented in the SWAT model. Methods for calculating industrial water use include the quota method and the trend method. The formula for the quota method is $W_i = V imes K_i$, where $W_i$ represents industrial water demand, $V$ is industrial output value (in ten thousand yuan), and $K_i$ is water demand per ten thousand yuan of industrial output value. Domestic water use is calculated using the quota method, which is derived by multiplying per capita water consumption by the total population. Eco-environmental water use is calculated using the evapotranspiration method based on the Penman-Monteith equation implemented in the SWAT model to simulate eco-environmental water consumption. Total available water resources are equal to the runoff generated by precipitation.
