Comprehensive evaluation and obstacle factor analysis of water security in Heilongjiang Province based on water footprint

Oct 22, 2026

Amid intensifying global climate change and rapid socioeconomic development, water security in Heilongjiang Province is assessed through an integrated framework combining water footprint theory and the Driving Force-Pressure-State-Impact-Response (DPSIR) model. The study builds a 5-criterion-layer, 45-indicator evaluation index system and applies entropy weighting, linear weighting, coupling coordination degree (CCD), and obstacle-degree modeling to trace 2000–2022 changes. Results show overall improvement from medium to very high safety, CCD consistently above 0.98, coordination shifting to basic coordination, and driving force as the primary constraint.

This study integrates water footprint theory and the Driving Force-Pressure-State-Impact-Response (DPSIR) model to construct a WS evaluation index system comprising 5 criterion layers and 45 indicators. Utilizing an integrated approach comprising the entropy weighting method, linear weighting method, coupling coordination degree (CCD) model, and obstacle degree model, the research systematically analyzes the evolution and obstacle factors of WS system in Heilongjiang Province from 2000 to 2022. The results indicate that: (1) The WS system in Heilongjiang Province exhibited an overall positive trend, progressed from medium safety (2000-2002) to high safety (2003- 2007) and ultimately to very high safety (2008-2022). Despite overall improvement, disparities in development rates of these layers resulted in persistent systemic imbalances. (2) The system coupling degree consistently exceeded 0.98 (high coupling), while coordination shifted from moderate imbalance (2000-2018) to basic coordination (2019-2022). A significant positive correlation existed between CCD and water security index (WSI). (3) Obstacle analysis identified the driving force dimension as the primary constraint. Dominant obstacle factors at the specific metrics level transitioned from engineering-ecological-economic factors in 2000 towards social- * Corresponding authors.

FAQs

How is water security in Heilongjiang Province evaluated in the study?

The study integrates water footprint theory with the DPSIR model, constructing an evaluation index system with 5 criterion layers and 45 indicators, then applies entropy and linear weighting plus coupling coordination and obstacle-degree methods.

What overall trend in water security is reported for 2000–2022?

Water security shows an overall positive trend, moving from medium safety (2000–2002) to high safety (2003–2007) and finally to very high safety (2008–2022).

Which systemic obstacle is identified as the primary constraint?

Obstacle analysis identifies the driving force dimension as the primary systemic obstacle, and dominant metric-level obstacles shift from engineering-ecological-economic factors toward social-economic-management factors by 2022.
