摘要
生态足迹表征区域持续提供资源、消纳废物且具有生产性的能力。利用生态足迹模型对唐山市2001～2016年水资源进行量化评价,结果表明研究时域内该市水资源足迹呈波动先增后缓的特征,生态承载力趋于增加;各产业中以农业用水生态足迹降低、生活用水生态足迹增加为主要特征;从各县域来看,中心城区的生态足迹较大、承载压力也较重,而燕山南麓和东北部地区水资源相对丰富、生态足迹较低。
the ecological footprint represents the region's ability to provide resources, eliminate waste and be productive. In this paper, the ecological footprint model is used to quantify the water resources of Tangshan City from 2001 to 2016. The results show that the water resources footprint of Tangshan City has the characteristics of fluctuation first increasing and then slowing, and the ecological carrying capacity tends to increase. In each industry, the ecological footprint of agricultural water is reduced and the ecological footprint of domestic water is increased. From the point of view of each county, the ecological footprint of the central city is relatively large and the carrying pressure is also heavy, while the water resources in the southern foothills of Yanshan and the northeastern regions are relatively rich and the ecological footprint is low.
