基于改进水生态足迹模型的深圳市水资源可持续利用分析

基于传统水生态足迹模型,在优化水资源均衡因子的基础上构建了基于市公顷的水生态足迹模型,计算了深圳市2004~2018年间水资源均衡因子、各区水资源产量因子、水资源生态足迹和水生态压力指数,对水资源可持续发展水平进行了研究。结果表明,深圳市水资源均衡因子逐步增加;水资源产量因子总体呈现由东向西递减趋势;水资源生态足迹周期性波动缓慢上升,各区的水生态足迹呈现明显的空间差异性;水生态压力指数整体大于1,水资源处于不可持续发展状态。

Sustainable Utilization of Water Resources in Shenzhen City Based on Improved Water Ecological Footprint Model

Based on the traditional water ecological footprint model,a new one was constructed in the municipal scale by optimizing water resources equivalence factor.And water equivalence factor,water yield factors of various districts,water ecological footprint,water ecological pressure index in Shenzhen City from 2004 to 2018 were calculated to study the level of water resources sustainable development.The results show that the water equivalence factor of Shenzhen has gradually increased;The yield factors generally show a decreasing trend from east to west;The ecological footprint of water resources fluctuates cyclically and slowly,and the water ecological footprint of each area shows obvious spatial differences;The overall water ecological pressure index is greater than 1,and water resources are in an unsustainable development status.
