Adaptability of economy and water system in Middle Route of the South-to-North Water Transfers Project water source area:Taking Nanyang City as an example
The research focused on six counties and districts in Nanyang City,which is a vital part of the water source area for the Middle Route of the South-to-North Water Transfers Project.The study aimed to explore the adaptability between water ecology and economic development.The study aimed to assess the progress made in the region regarding the protection of water ecology and economic advancement.An evaluation index system for system adaptability was constructed based on the Pressure-State-Response(PSR)model using economic scale,economic structure,economic vitality,economic potential,economic response,water ecological status,water ecological pressure,and water ecological response.The Kaley weighting method was applied to distribute weights to various indicators.The system adaptability of the six counties and districts in Nanyang City from 2012 to 2022 was calculated,and an in-depth analysis of their spatiotemporal differences and changing trends was conducted.The study's findings were as follows:(1)The overall system adaptability of the six counties and districts in Nanyang City showed an upward trend during the research period,indicating positive progress in the region's water ecological conservation and economic development.(2)The changes in system adaptability among the counties exhibited strong convergence,closely related to agriculture being the primary pillar industry in these areas.(3)With the launch of the Middle Route Project for water transfer,the adaptability of the six counties and districts in Nanyang City has considerably improved.This advancement has not only enhanced water resource conditions but has also positively influenced the local ecological environment,agricultural and industrial development,and the optimization of the economic structure.The study revealed the interactive relationship between water ecological protection and sustainable economic development in the study area.It provided a scientific basis for formulating regional development strategies and water resource management policies.The research emphasized that regional development under the influence of large-scale hydraulic projects should consider the coordination between ecological conservation and economic growth to achieve proper sustainable development.
