摘要
碳足迹和水资源生态足迹是衡量人类活动对环境影响程度的重要指标。影响碳足迹与水资源生态足迹因素很多,收集宁夏沿黄城市带2010—2019年相关资料,从人口、经济、生产技术和自然领域建立12个指标进行研究,并通过构建可拓展的随机性的环境影响评估模型(Stochastic Impacts by Regression on Population,Affluence,and Technology,STIRPAT),对宁夏沿黄城市带碳足迹及水资源生态足迹的驱动机制进行分析。结果显示:由于地区间差异会导致不同城市足迹的影响因素及作用强度不尽相同。其中,碳足迹驱动因素在银川市主要为人口、城镇化率和第二产业占比,石嘴山市为人口、万元GDP耗水量以及第二产业占比,吴忠市为第二产业占比、人口及GDP总值;水资源生态足迹驱动因素在银川市主要为人口、城镇化率和降水,石嘴山市为人口及生产技术水平,吴忠市为人均水资源量、降水及植被覆盖率。中卫市碳足迹与水资源生态足迹的主要影响因素均为生产技术水平和自然因素。在工业相对发达区域,碳水影响因素及程度有一定相似性,可以通过同步调控实现节水减碳。
Carbon footprint and water resource ecological footprint are important indicators to measure the impact of human activities on the environment.Many factors affect the carbon footprint and water ecological footprint.This paper collected data on the urban belt along the Yellow River in Ningxia from 2010 to 2019 and set 12 indicators in terms of population,economy,production technology,and natural area.Through the construction of the STIRPAT model,the driving mechanism of carbon footprint and water resources ecological footprint of the urban belt along the Yellow River is analyzed.The results show that regional differences lead to different influencing factors and different intensities of the urban footprint.The driving factors of Yinchuan’s carbon footprint are mainly the proportion of the population,secondary industry,and urbanization rate.Shizuishan City includes population,water consumption per 10000 yuan GDP,and the proportion of secondary industry.Wuzhong City includes secondary industry,population,and GDP;The driving factors of water resources ecological footprint in Yinchuan include population,urbanization rate,and rainfall,while Shizuishan includes population and production technology level;Wuzhong City includes per capita water resources,precipitation,and vegetation coverage.The main influencing factors of Zhongwei’s carbon footprint and water resources ecological footprint are the level of production technology and natural factors.Economic factors play a role in promoting the growth of the water carbon footprint,while technical factors have a certain inhibitory effect.In developed industrial regions.Water carbon footprint is affected by similar factors and degrees.However,in general,there is a certain correlation between urban carbon and water resources ecological footprint in the urban belt along the Yellow River in terms of influencing factors,but the correlation has no obvious regularity.The influence factors of water and carbon pressure are similar in relatively developed areas,but there is no obv
