摘要

背景生态系统服务是居民福祉的基础,也是制定区域可持续发展决策的重要依据。现有研究主要通过问卷调查获取居民感知的生态系统服务,或通过经济评估和生物物理评估量化区域生态系统服务的提供。方法 在本研究中,我们通过生物物理模型和问卷调查,量化了官厅水库流域九种生态系统服务的潜在供应量和居民对这些服务的感知。结果表明,在绝大多数居民中,九项生态系统服务中有一半的感知值与模型计算值之间存在显著差异。在城市居民中,调节和支持服务的差异更为明显,而在农村居民中,供给和文化服务的差异则更为明显。在快速城市化的流域中,应加强农村地区的基础设施建设,以提高农村居民获得生态系统服务的能力。在城市地区,应特别关注调节和支持服务的变化。

Perceived ecosystem services differ substantially from calculated services using biophysical models

Context

Ecosystem services are fundamental for the well-being of residents and are an important basis for making regional sustainable development decisions. Existing studies mainly capture ecosystem services perceived by residents through questionnaires, or quantify the provision of regional ecosystem services through economic evaluation and biophysical evaluation. However, the discrepancy between model calculations and residents' perceptions remains lacking.

Objectives

Rapidly urbanizing watersheds can serve as a prime example for exploring the differences in ecosystem service outcomes between the two perspectives.

Methods

In this study, we quantified the potential supply of nine ecosystem services and residents' perceptions of these services in the Guanting Reservoir basin through biophysical modelling and questionnaire surveys. We then analyzed the discrepancies between the two perspectives through the Wilcoxon signed-rank test.

Results

The results showed that among the vast majority of the population, half of the nine ecosystem services exhibited significant differences in comparisons between perceived values and model-calculated ones. The differences were more prominent for regulating and supporting services among urban residents, while for provisioning and cultural services among rural residents.

Conclusions

These differences highlight the necessity to consider quantitative results from diverse perspectives as well as on the benefits of different groups of interest. In rapidly urbanizing watersheds, infrastructure should be reinforced in rural areas to enhance rural residents’ accessibility of ecosystem services. With regard to urban areas, particular attention should be directed towards changes in regulating and supporting services.

期刊介绍: Landscape Ecology is the flagship journal of a well-established and rapidly developing interdisciplinary science that focuses explicitly on the ecological understanding of spatial heterogeneity. Landscape Ecology draws together expertise from both biophysical and socioeconomic sciences to explore basic and applied research questions concerning the ecology, conservation, management, design/planning, and sustainability of landscapes as coupled human-environment systems. Landscape ecology studies are characterized by spatially explicit methods in which spatial attributes and arrangements of landscape elements are directly analyzed and related to ecological processes.
