摘要: 秦岭是我国重要的生态功能区,探究秦岭生态系统服务权衡与协同关系对区域的生态保护和高质量发展意义重大。本研究基于遥感、气象、土壤质地等数据,在分析2000、2010和2020年土地利用时空变化的基础上,采用CASA、InVEST和RUSLE模型计算秦岭地区植被固碳量、产水量、生境质量和土壤保持量,并探讨空间异质性特征及生态系统服务关系。结果表明: 2000—2020年,研究区耕地、草地面积持续减少,林地和建设用地面积增长,水域和未利用地变化不明显。研究区固碳量东高西低,呈增长趋势;产水量持续减少,呈现南坡高、北坡低的格局;生境质量稳定增长;土壤保持量先增后减。不同地类的生态系统服务各有差异,同一地类的各个生态系统服务也各不相同。全域尺度下固碳与土壤保持、生境质量与土壤保持、固碳与生境质量皆呈协同关系,固碳与产水、土壤保持与产水、生境质量与产水为权衡关系,但不同条件下服务量间的关系存在明显差异。研究结果有助于降低权衡风险,使总体效益最大化,可为促进生态高质量发展、实现自然资源管理与人类福祉的双赢提供参考依据。

Abstract: The Qinling Mountains are an important ecological function area in China. Exploring the trade-offs and synergies of ecosystem services is important for ecological protection and sustainable development in the Qinling Mountains. In this study, we analyzed the spatio-temporal variations of land uses in the Qinling Mountains in 2000, 2010 and 2020 based on remote sensing, meteorological, and soil texture data. The amounts of carbon sequestration, water yield, habitat quality, and soil conservation were calculated with CASA, InVEST and RUSLE models. The relationships between its spatially heterogeneous characteristics and various ecosystem services were analyzed. The results showed that, from 2000 to 2020, the area of arable land and grassland in the study area continued to decrease, the area of forest and building land increased, and the change of water body and unused land was not noticeable. Carbon sequestration was high in the east and low in the west, with an increasing trend. Water production continued to decrease, showing a tendency of higher on the south slope and lower on the north slope. Habitat quality increased steadily, while soil conservation increased and then decreased. Ecosystem services varied across land classes and across ecosystems in the same land class. In general, there was a synergistic relationship between carbon sequestration and soil conservation, habitat quality and soil conservation, carbon sequestration, and habitat quality. There was trade-off between carbon sequestration and water production, soil conservation and water production, habitat quality, and water production. There were significant differences in the relationship between service volumes under different conditions. The results could reduce the risk of trade-offs and maximize overall benefits, and provide a reference for promoting ecologically high-quality development and achieving a win-win situation for natural resource management and human well-being.
