“…In recent years, with the rapid development of China's economy, groundwater resources have been over-exploited in most areas of northern China, leading to the decay of groundwater resources as well as water resource pollution (Wang et al, 2023;Liu et al, 2022;Ji et al, 2019). As the most signi cant agricultural production base in northern China, The Weibei Plain has been over-exploiting groundwater for a long time to maintain the rapid development of agriculture (Fan et al, 2022;Hu et al, 2018).…”

Nitrate pollution in groundwater has become an issue that cannot be overlooked, specifically in areas where there is intense agricultural groundwater extraction. This study focuses on the Weibei Plain, where 46 shallow groundwater monitoring wells were selected for sampling during the dry and wet seasons in 2016 and 2021. The purpose of this study was to analyze the regional groundwater hydrogeochemistry and investigate the temporal or spatial variation of nitrate content. The results demonstrated that the groundwater in the study area had a weakly alkaline nature. The hydrochemical composition of the groundwater shifted from being dominated by HCO3-Ca-Mg in 2016 to HCO3-Na and SO4-Cl-Ca-Mg in 2021. The hydrochemical characteristics were predominantly impacted by both rock weathering and cation exchange. The average concentration of nitrate in the 184 samples was 25.93 mg/L, surpassing the drinking water limit of 20 mg/L. A significant correlation was observed between NO3- and Cl- as well as SO42-. The areas with high nitrate concentrations were predominantly located in the groundwater depression cone and regions with intensive agricultural activities, indicating that human activities were the main contributors to nitrate pollution. Furthermore, the nitrate concentration was significantly higher during the wet season compared to the dry season. This could be attributed to rainfall intensifying the infiltration of nitrate from the soil into the groundwater. Furthermore, there was a substantial increase in nitrate concentration in 2021 compared to 2016. This increase was primarily ascribed to the excessive exploitation of groundwater for irrigated agriculture, leading to a considerable influx of nitrate into the groundwater.

“…Research on the ecological environment of Inner Mongolia encompasses various aspects and employs diverse methodologies. These include monitoring and analyzing land use and land cover changes using remote sensing techniques such as satellite imagery [18]; studying vegetation cover changes through remote sensing data and ground surveys [19]; researching water resources and the water environment by monitoring rivers, lakes, and hydrological systems [20]; analyzing grassland ecosystems to assess biodiversity, vegetation cover, and degradation [11]; investigating desertification and desertification expansion using remote sensing and ground observations [21]; examining the impacts of climate change on the ecological environment [22]; assessing biodiversity conservation by surveying flora and fauna species [23]; and evaluating ecosystem services such as water conservation [24], soil retention [25], and climate regulation [26]. Although extensive research has been conducted, continuous long-term monitoring of ecological environment quality and research into driving factors remain imperative.…”

With the escalating global climate change and frequent human activities, Inner Mongolia, as a crucial ecological barrier in the Beijing-Tianjin-Hebei region, Bohai Economic Rim, and even the whole country, confronts many ecosystem issues. To reveal the intricate interplay between natural processes, human activities, and policy interventions shaping the region’s ecological landscape, we provide a comprehensive analysis of ecological quality in Inner Mongolia from 2002 to 2021. Key findings include: (1) The research uncovers an overall improvement in ecological quality across Inner Mongolia, albeit with certain regions exhibiting a pattern of deterioration followed by improvement, particularly notable in the central part of the province. (2) Cropland, shrub, grassland, barren, wetland, and water are decreasing, while impervious, and forestland are increasing. (3) Precipitation, temperature, and elevation are significant drivers affecting the quality of the ecological environment. Interestingly, while human production and activities have altered ecological conditions, factors like GDP, population density, and night lighting index do not directly impact environmental quality significantly. This underscores the intricate interplay among various factors within the socioeconomic system, highlighting its complexity. (4) Based on these findings, our policy recommendations include strengthening ecological monitoring and management, promoting sustainable urban development, conducting public education and awareness campaigns, and fostering stakeholder collaboration for data sharing and collective understanding. Adopting sustainable management strategies is essential for promoting ecological resilience and mitigating environmental degradation in Inner Mongolia, not only benefiting the local ecosystem but also contributing to national and global environmental well-being.
