摘要:

生态系统服务在维持生态安全、可持续发展和人类福祉方面发挥着重要作用。本研究以内蒙古荒漠草原为研究区,分别对2000、2017年水源涵养、土壤保持、生境质量、游憩潜力进行定量评估,分析其时空分布特征,探讨服务间的权衡/协同关系,并识别不同服务簇的主导服务类型和空间格局。结果表明:从2000-2017年,各项生态系统服务的空间异质性显著,水源涵养服务的高值区域主要集中在东南部和西南部,土壤保持高值位于西南部,生境质量和游憩潜力的分布都较随机。各项生态系统服务主要呈现降低趋势;大部分服务对间表现为协同关系,而土壤保持和生境质量服务对表现为权衡关系,服务对间的相关性程度有所降低;生态系统服务簇分为土壤保持、人居环境、水源涵养三个功能区,具有明显的空间异质性。土壤保持区,主要土地利用类型为未利用地,未来的管理要限制放牧数量,通过改变地表植被覆盖来影响土壤可侵蚀性。人居环境区,草地覆盖度高,为人类活动提供优良场所,促进生态旅游等多产业协同发展。水源涵养区,土地利用类型主要为中覆盖度草地和低覆盖度草地,未来管理以蓄水保水为主,坚持生态优先,实现该区域生态可持续发展。

Abstract:

Ecosystem services play an important role in maintaining ecological security, sustainable development and human well-being. In this rresearch, the study area was the desert steppe of Inner Mongolia and a quantitative assessment of water conservation, soil conservation, habitat quality, and recreational potential in 2000 and 2017 was carried out. Their spatial and temporal distribution characteristics and the trade-offs and synergies between services are analyzed and discussed; the dominant service types and spatial patterns of different service bundles are identified. It was found that: from 2000 to 2017, the spatial heterogeneity of various ecosystem services was significant. The high-value areas of water conservation services are mainly concentrated in the southeast and southwest; the high value soil conservation is located in the southwest; the distribution of habitat quality and recreational potential is more random. Various ecosystem services show a mainly decreasing trend; most service pairs show a synergistic relationship, while soil conservation and habitat quality service pairs show a trade-off relationship, and the degree of correlation between service pairs decreases. Ecosystem service bundles are divided into three functional areas of soil conservation, living environment and water conservation and have obvious spatial heterogeneity. In the soil conservation area, the main land use type is unused land, and future management should limit the amount of grazing and seek to influence soil erodibility by changing the surface vegetation cover. The human settlement area, with high grassland cover provides excellent scope for human activities and the coordinated development of multiple industries such as eco-tourism. In the water conservation area, the land use types are mainly grassland with medium cover and grassland with low cover. Future management should focus on water storage and water conservation, adhere to ecological priorities, and pursue ecologically sustainable development in this area.
