摘要

研究生态系统服务之间的权衡与协同关系及其驱动机制的规模效应，是综合推进生态环境协同治理与区域可持续发展的重要突破口。利用InVEST模型定量评价2022年玛纳斯河流域供水、水土保持、生境质量和碳储量4种服务功能及其空间格局，利用空间叠加法探索不同尺度下服务功能的空间分异格局，利用随机森林模型挖掘不同尺度下服务功能的自然背景和社会经济学机制。结果表明：(1)玛纳斯河流域4种典型ESs均表现出显著的空间异质性。(2) TOS的空间演化格局存在尺度效应，1 km × 1 km、10 km × 10 km和子流域尺度是TOS变化的“拐点”。(3) TOS对自然因素和社会因素的响应在不同尺度上存在差异。(4)地表温度与驱动因子呈非线性相关关系，且在子流域尺度上地表温度对影响因子的响应差异比栅格尺度上更为明显。

Scaling effects of ecosystem service trade-off and synergy in arid inland river basins: A case study of the Manas River Basin of Xinjiang, China

The study of trade-off and synergy relationships (TOS) among ecosystem services (ESs) and the scale effects of their driving mechanisms is an important breakthrough for the integrated promotion of synergistic ecosystem-environmental governance and regional sustainable development. In this paper, we used the InVEST model to quantitatively assess the four types of service functions and spatial patterns of water supply, soil conservation, habitat quality, and carbon storage in the Manas River Basin in 2022, explored the spatial differentiation patterns of TOS at different scales by spatial superposition method, and mined the mechanisms of the natural background and socioeconomics of the TOS at different scales using the random forest model. The main conclusions are as follows: (1) All four typical ESs in the Manas River Basin showed significant spatial heterogeneity. (2) There is a scale effect in the spatial evolution pattern of TOS, and 1 km × 1 km, 10 km × 10 km, and sub-watershed scales are the “inflection points” of TOS changes. (3) The response of TOS to natural and social factors varies at different scales. (4) The correlation between TOS and the driving factors is nonlinear, and the difference in the response of TOS to the influencing factors is more obvious at the sub-watershed scale than among the raster scales.

期刊介绍： The ultimate aim of Ecological Indicators is to integrate the monitoring and assessment of ecological and environmental indicators with management practices. The journal provides a forum for the discussion of the applied scientific development and review of traditional indicator approaches as well as for theoretical, modelling and quantitative applications such as index development. Research into the following areas will be published. • All aspects of ecological and environmental indicators and indices. • New indicators, and new approaches and methods for indicator development, testing and use. • Development and modelling of indices, e.g. application of indicator suites across multiple scales and resources. • Analysis and research of resource, system- and scale-specific indicators. • Methods for integration of social and other valuation metrics for the production of scientifically rigorous and politically-relevant assessments using indicator-based monitoring and assessment programs. • How research indicators can be transformed into direct application for management purposes. • Broader assessment objectives and methods, e.g. biodiversity, biological integrity, and sustainability, through the use of indicators. • Resource-specific indicators such as landscape, agroecosystems, forests, wetlands, etc.
