Comprehensive Evaluation and Coupled Coordinated Development Study of Water–Economic–Ecological Systems in the Five Northwestern Provinces of China

Abstract

The five northwestern provinces face numerous challenges in sustainable development, particularly water scarcity, economic imbalances, and ecological degradation. This study aims to deeply assess the region’s water resource conditions, the current status of economic development, and the health of the ecosystem while exploring the relationships and coupling mechanisms among them. Using the obstacle model, the research analyzes the primary barriers affecting these three significant factors in the region. The study further reveals a continually improving trend of coordinated development within the water–economic–ecological system in the five northwestern provinces of China, indicating that water usage per ten thousand GDP is the primary obstacle. This research enriches our understanding of the development in China’s five northwestern provinces and provides a theoretical foundation for achieving sustainable development.

Can the Establishment of National Parks Promote the Coordinated Development of Land, the Environment, and Residents’ Livelihoods?

“…To date, the majority of both national and international studies examining the interplay among land, the economy, and ecology has originated from a solitary subsystem or has focused on the interconnection and synchronization of two subsystems, with a lesser emphasis on the interplay among all three subsystems [4,5]. Earlier research primarily concentrated on the qualitative analysis of implications, connections, and traits [6], whereas subsequent studies predominantly utilized quantitative research models [7][8][9]. In the majority of contemporary studies, a systematic evaluation index system is developed by employing methods like the entropy value, principal component analysis, and multiindex comprehensive evaluation, and the comprehensive score is computed by a coupling Land 2024, 13, 704 2 of 18 coordination model [10][11][12].…”
