摘要
[目的]对福建省水资源生态承载力进行研究,为该区水资源可持续利用提供科学依据。[方法]以水资源生态足迹作为理论基础,叠加水资源生态足迹三维模型,并以福建省2010—2019年数据为主,分析福建省水资源生态足迹、水资源生态承载力以及水资源空间格局。[结果]福建省2010—2019年水资源生态足迹总体呈下降趋势,变化范围为0.696~0.928 hm^(2)/人;水资源生态承载力受降水影响,年际变幅较大,变化范围为2.602~10.944 hm^(2)/人,为水资源生态盈余。万元GDP水资源生态足迹呈现明显下降趋势;福建省西部地区水资源承载力明显好于东部沿海地区。水资源足迹深度为1,水资源足迹广度波动范围在1以下,并呈下降趋势。[结论]福建省水资源比较丰富。目前条件下,该省水资源承载力能够满足当地经济发展。但福建省水资源承载力年际变化较大,空间分布差异较大,随着经济的发展,水资源还是存在一定风险。
[Objective]The ecological carrying capacity of water resources in Fujian Province was studied,in order to provide a scientific basis for the sustainable utilization of water resources in this area.[Methods]Based on the theory of ecological footprint,the 3D model of water ecology carrying capacity was imposed and the data from 2010 to 2019 in Fujian Province was used,to analyze the water ecological footprint,water ecological carrying capacity and spatial pattern of water resources.[Results]From 2010 to 2019,the general trend of per capita water ecological footprint in Fujian Province showed a decreasing trend with a range of 0.696 hm^(2)/person to 0.928 hm^(2)/person.The per capita water ecological carrying capacity ranged from 2.602 hm^(2)/person to 10.944 hm^(2)/person and was greatly affected by precipitation.Water resources showed ecological surplus.The tendency of ecological footprint of ten thousand-yuan GDP showed an obvious downward trend.The water carrying capacity in the western part was obviously better than that in the eastern coastal area.The water resources footprint depth was 1,and the value of water resources footprint size was below 1 in recent years.Meanwhile,it showed a downward trend.[Conclusion]Water resources are rich in Fujian Province.In recent years,water resources well supported the local development.However,the water carrying capacity in Fujian Province varied greatly from year to year and the spatial distribution is quite different.With the development of social economy,there are still some risks in water resources.
