Human settlement water security in Northern Xinjiang China based on DPSIR model

Area of Science:

• Environmental Science
• Ecology
• Water Resource Management

Background:

• Water resource ecological security is crucial for human survival and ecosystem stability.
• A comprehensive evaluation is needed to understand regional water ecological security.
• The DPSIR (driving force-pressure-state-impact-response) paradigm offers a structured approach.

Purpose of the Study:

• To develop and apply a comprehensive index system for evaluating regional water ecological security.
• To analyze the spatial and temporal characteristics of water ecological security.
• To assess regional ecological carrying capacity and identify areas of concern.

Main Methods:

• Utilized the DPSIR (driving force-pressure-state-impact-response) paradigm to construct an evaluation index system.
• Employed entropy weight TOPSIS to determine the weights of each index.
• Analyzed spatial differentiation and temporal-spatial deduction characteristics of water ecological security.

Main Results:

• The DPSIR model revealed clear spatial differentiation in water ecological security.
• Northern border areas exhibited spatiotemporal fluctuations from 2014-2023: increase-decline-recovery.
• Regional ecological carrying capacity showed a trend of low in the northeast and strong in the southwest.

Conclusions:

• Water ecological security demonstrates complex spatiotemporal patterns requiring tailored management strategies.
• Tacheng, Ili Kazakh Autonomous Prefecture, and Urumqi show the highest water resource carrying capacities.
• The findings provide critical insights for sustainable water resource management and policy development.
