Abstract

Study region

Heilongjiang Province, north-eastern region of China.

Study focus

Water resources are important resources for steady economic and social progress, and the coordination between water resources consumption and economic development is the prerequisite for ensuring sustainable regional development. This study aims to promote the coordination of water resources consumption and economic development in Heilongjiang Province. In this study, system dynamics was used as a technical tool to simulate the water consumption and economic benefits of Heilongjiang Province from 2000 to 2050. The nonlinear trend of water resources consumption and economic development in Heilongjiang Province was explored by using the Sequential T-Test analysis of regime shifts (STARS) and the threshold generalized additive models (TGAM) for the first time.

New hydrological insights for the region

The results indicated the following: (1) No nonlinear changes in agricultural water footprint (WF_A) were detected in Heilongjiang Province. Both the industrial water footprint (WF_I) and the domestic water footprint (WF_D) showed one nonlinear change in 2018. Two nonlinear changes in ecological water footprint (WF_E) in 2021 and 2033. (2) The WEF in Heilongjiang Province fluctuated, reaching a peak of 8.32 × 10⁷ hm² in 2007 and a low of 4.31 × 10⁷ hm² in 2019. The water ecological footprint (WEF) per 10⁴ yuan GDP decreased from 2.39 hm²/10⁴ yuan to 0.29 hm²/10⁴ yuan. (3) Thresholds in the total WF and WEF with GDP were detected in 2010 and 2017. (4) The decoupling of the WF and WEF from economic development in Heilongjiang Province was mostly in intermediate optimal state, but with higher water consumption. The findings provide valuable insights for accelerating the green transformation of Heilongjiang Province and fostering the economy's and water resources' outstanding development.

期刊介绍： Journal of Hydrology: Regional Studies publishes original research papers enhancing the science of hydrology and aiming at region-specific problems, past and future conditions, analysis, review and solutions. The journal particularly welcomes research papers that deliver new insights into region-specific hydrological processes and responses to changing conditions, as well as contributions that incorporate interdisciplinarity and translational science.
