Abstract

Context

Water-regulation services significantly affect local social and economic development in the Qinghai area of Qilian Mountain National Park, China, and also affect the role of a ‘solid reservoir’ in China.

Aim

The value and change trend of water regulation was assessed through the evaluation and prediction of the water-regulation value of ecosystems.

Methods

InVEST water yield model and SVR model are used to evaluate and predict the water-regulation value of ecosystem in this study.

Key results

Grassland plays an important role in water regulation, although the area of forestland is not large, its water-regulation monetary value in 2020 accounted for 13.92% of the total evaluation value. From 2010 to 2020, the physical value of water regulation increased by 2.24% and the monetary value increased ~0.97% annually. In 2030, the amount of physical and monetary value of water regulation will be increased.

Conclusion

Grassland plays an important role in water regulation. It is necessary to strengthen the asset management of water regulation and optimise the ecological resources.

Implications

The study findings are utilised to enhance monitoring and establish ecological big-data platform, thereby elevating the quality of national park development management and decision-making services.

中国祁连山国家公园青海地区生态系统水调节价值评估与分析

背景水调节服务极大地影响了中国祁连山国家公园青海地区的社会和经济发展，也影响了中国 "固体水库 "的作用。目的通过评估和预测生态系统的水调节价值，评估水调节的价值和变化趋势。方法采用InVEST产水量模型和SVR模型对生态系统的水调节价值进行评价和预测。主要结果草地在水调节中发挥着重要作用，虽然林地面积不大，但其 2020 年的水调节货币价值占总评估价值的 13.92%。从 2010 年到 2020 年，水调节的物理价值每年增长 2.24%，货币价值每年增长 ~0.97%。2030 年，水调节的物理价值和货币价值都将增加。结论草地在水调节中发挥着重要作用。有必要加强水调节的资产管理，优化生态资源。启示利用研究结果加强监测，建立生态大数据平台，从而提高国家公园发展管理和决策服务的质量。

期刊介绍： Marine and Freshwater Research is an international and interdisciplinary journal publishing contributions on all aquatic environments. The journal’s content addresses broad conceptual questions and investigations about the ecology and management of aquatic environments. Environments range from groundwaters, wetlands and streams to estuaries, rocky shores, reefs and the open ocean. Subject areas include, but are not limited to: aquatic ecosystem processes, such as nutrient cycling; biology; ecology; biogeochemistry; biogeography and phylogeography; hydrology; limnology; oceanography; toxicology; conservation and management; and ecosystem services. Contributions that are interdisciplinary and of wide interest and consider the social-ecological and institutional issues associated with managing marine and freshwater ecosystems are welcomed. Marine and Freshwater Research is a valuable resource for researchers in industry and academia, resource managers, environmental consultants, students and amateurs who are interested in any aspect of the aquatic sciences. Marine and Freshwater Research is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
