摘要:

探究生态系统服务功能动态变化特征及其驱动机制,可为实施区域生态系统保护与修复提供科学参考。大量研究以单一尺度对区域内生态系统服务权衡/协同关系进行描述,有关多尺度下生态系统服务权衡协同关系及多种生态系统服务影响差异性的研究尚缺乏。本文选取首都西部生态涵养区为研究对象,采用2000、2010、2020、2023年遥感数据,运用InVEST等模型量化产水量、碳储量、土壤保持和生境质量共4类主要生态系服务功能,并用地理加权回归模型与最优地理探测器模型分析不同尺度下的权衡/协同关系。结果表明:(1)2000—2023年,首都西部生态涵养区生境质量基本保持不变,产水量、土壤保持量分别上升了2.96×108 m3、1.69×108 t,碳储量下降了3×106 t,减少区域主要涉及房山区霞云岭乡、良乡镇、窦店镇等;空间上,生态系统服务高值区主要分布在研究区北部、西北部地区,低值区主要分布在研究区东南部。(2)整体上首都西部生态涵养区生态系统服务以协同为主;空间上各服务之间协同面积均大于权衡面积,并且随着尺度扩展,权衡面积不断减小。(3)高程和蒸散发是影响研究区生态系统服务协同和权衡的主要因素,各因素与高程、年蒸散发之间的交互影响呈现出较强的解释力。研究结果揭示首都西部生态涵养区生态系统服务供给能力的时空演替态势,以及从不同尺度揭示生态系统服务之间的权衡协同度,为首都西部生态涵养区生态保护修复提供科学依据。

Abstract:

Exploring the dynamic changes and driving mechanisms of ecosystem service functions can provide scientific references for the implementation of regional ecosystem protection and restoration. A large number of studies have described the trade-offs and synergies of ecosystem services within a single scale in a region, but research on the trade-offs and synergies of ecosystem services at multiple scales and the differences in the impacts among multiple ecosystem services is still lacking. This paper takes the ecological conservation area of western Beijing as the research object, uses four periods of remote sensing data from 2000, 2010, 2020, and 2023, and quantifies four major ecosystem service functions, including water yield, carbon storage, soil retention, and habitat quality, using models such as InVEST. The Geographically Weighted Regression model and the Optimal Geodetector model are used to analyze the trade-offs and synergies at different scales. The results show that: (1) From 2000 to 2023, the habitat quality in the ecological conservation area of western Beijing remained basically unchanged, while water yield and soil retention increased by 2.96×108 m3 and 1.69×108 t respectively, and carbon storage decreased by 3×106 t. The areas with the most significant reduction mainly involved Xiaoyunling Township, Liangzhuang Township, and Douzhen Town in Fangshan District. Spatially, the high-value areas of ecosystem services were mainly distributed in the northern and northwestern parts of the study area, while the low-value areas were mainly located in the southeastern part. (2) Overall, the ecosystem services in the ecological conservation area of western Beijing were mainly synergistic; spatially, the area of synergy between each service was greater than the area of trade-off, and the area of trade-off decreased continuously with the expansion of the scale. (3) Elevation and evapotranspiration were the main factors affecting the trade-offs and synergies of ecosystem services in the study area, and the interaction between each factor and elevation and annual average evapotranspiration showed strong explanatory power. The research results reveal the spatio-temporal evolution trend of the ecosystem service supply capacity in the ecological conservation area of western Beijing, as well as the degree of trade-offs and synergies among ecosystem services at different scales, providing a scientific basis for the ecological protection and restoration of the ecological conservation area of western Beijing.
