“…The Yangtze River and Yellow River hold profound significance as the nurturing lifelines of the Chinese nation. The development of YRB and YREB has garnered considerable scholarly attention, and a series of studies have been conducted on water-soil disasters and governance (Jiang et al, 2021b;Hu et al, 2022;Liu et al, 2023b), the impacts of climate change (Yang et al, 2023b;Zhang et al, 2023), the functions of ecological service (Pan et al, 2021b;Fang et al, 2021), education, healthcare and poverty alleviation and other livelihood issues (Zhou et al, 2022;Ren et al, 2023), etc. In recent years, the issue of HQD in both basins has progressively become a key focus of scholars, who have concentrated their efforts on formulating policies and delineating developmental trajectories aligned with the principles of HQD within the geographical regions (Chen et al, 2022), HQD of the economy and industries (Geng and Wang, 2023), HQD of construction, water conservancy, agriculture, transportation and other industries (Chen et al, 2023;Wang, 2022).…”

Based on China’s new development philosophy, and following the idea of “assessing the overall levels firstly, then anchoring the subsystems contributions and finally identifying the obstacle factors”, an evaluation system of high-quality development (HQD) levels is constructed from five subsystems of innovative development (ID), coordinated development (CD), green development (GD), open development (OD) and shared development (SD). In this paper, the entropy weight TOPSIS model is used to measure the HQD levels of 19 provincial units located in the Yellow River Basin (YRB) and the Yangtze River Economic Belt (YREB) in 2010–2019, and with the assistance of the Obstacle Degree Model, the obstacle factors affecting the HQD of both are depicted. The results show that: (1) between 2010 and 2019, the HQD indices in YRB and YREB have been on an increasing trend, and the subsystems indices all show a trend of “GD > CD > SD > ID > OD”, but the overall levels of HQD in both is not high, and there is still much room for improvement. (2) YREB has a significantly higher HQD level than YRB. From 2010 to 2019, the average values of the HQD indices in YRB and YREB were 0.2886 and 0.4073, respectively, but the index in YRB improves at a faster pace than YREB, and the gap of HQD levels between the two show a trend of continuous reduction towards regional balance and coordination. (3) The analysis of obstacle factors shows that while OD and ID are the main obstacles to HQD in both basins, the impact of both on the resistance to HQD in both basins is on a decreasing trend. GD is another bottleneck for the HQD of YRB, and the pressure on GD in the middle and upper reaches of the provincial units in the basin is increasing, and the obstacles are on a rising trend.

Source information and the related influencing variables are crucial for watershed management. However, identifying long-term changes in pollution sources and distinct patterns remains challenging. Here we explore the changing patterns of pollution sources in the Hangbu Watershed of Chaohu Lake, China, and propose an adaptive strategy. The results demonstrate significant variations in sources over the 36-year study period, with nitrogen and phosphorus increasing by 1.2 times and 2.2 times, respectively. Compared to the traditional method based on a specific year, the adaptive solutions accounted for 87.83% and 57.68% of the nitrogen and phosphorus contribution. Trends, periodicity, and mutagenicity of sources were quantified, which are influenced by the variations in rainfall, urbanization, and agriculture development. Specifically, farmland acts as a vital source that exports 90.93% of nitrogen and 58.01% of phosphorus under different conditions. Specific pollution sources with growth trends and control robustness have been recognized as vital contributors, even though their contributions to the watershed's outlets may not be the most prominent. The results of this study enhance the sustainable management of watersheds.
