Abstract
As an important component of global surface water resources, river runoff is crucial for guiding regional ecological construction and sustainable utilization. However, there is a lack of knowledge regarding the impact of anthropogenic stress, including the development and utilization of water resources, soil and water control projects, land-use changes, and the construction of water conservancy projects, on changes in runoff in rocky mountain rivers. This study focused on the runoff variation and influencing factors of the Yihe River (YHR), a typical rocky mountain river in northern China, from 1951 to 2020. The results showed that the YHR’s runoff has shown a significantly decreasing trend from 1951 to 2020 and the annual runoff of YHR varied from 0.62 × 108 to 62.10 × 108 m3 with an average value of 20.23 × 108 m3/a over the past 70 years. There were three runoff variation periodicities, 6a, 12a, and 24a, respectively. Precipitation was the primary source of runoff in the YHR, which contributed 48.38% to runoff reduction between 1966 and 2020, and the impact of anthropogenic stress (including the development and utilization of water resources, soil and water control projects, land-use changes, and the construction of water conservancy projects) on the YHR runoff reduction exceeded natural factors from 1966 to 2020, with an average contribution rate of 51.62%. Thus, the ecological environment and water resource management of the YHR will face more serious challenges owing to continuously increasing anthropogenic stress in the future.
期刊介绍：
Environmental Earth Sciences is an international multidisciplinary journal concerned with all aspects of interaction between humans, natural resources, ecosystems, special climates or unique geographic zones, and the earth:
Water and soil contamination caused by waste management and disposal practices
Environmental problems associated with transportation by land, air, or water
Geological processes that may impact biosystems or humans
Man-made or naturally occurring geological or hydrological hazards
Environmental problems associated with the recovery of materials from the earth
Environmental problems caused by extraction of minerals, coal, and ores, as well as oil and gas, water and alternative energy sources
Environmental impacts of exploration and recultivation – Environmental impacts of hazardous materials
Management of environmental data and information in data banks and information systems
Dissemination of knowledge on techniques, methods, approaches and experiences to improve and remediate the environment
In pursuit of these topics, the geoscientific disciplines are invited to contribute their knowledge and experience. Major disciplines include: hydrogeology, hydrochemistry, geochemistry, geophysics, engineering geology, remediation science, natural resources management, environmental climatology and biota, environmental geography, soil science and geomicrobiology.
