摘要

[目的] 探讨青藏高原保护区2000—2010年生态系统服务功能对植被变化的响应，为进一步明晰生态系统服务功能和遥感植被指数的关系，为区域生态系统服务功能评估与生态保护提供科学参考。[方法] 聚焦青藏高原各类保护区，基于中分辨率成像光谱仪（MODIS）增强型植被指数（EVI）产品进行植被变化制图，针对碳固定、土壤保持、水源涵养、栖息地保护等生态系统服务功能，判断青藏高原保护区内2000—2010年生态系统服务功能变化趋势是否与植被变化趋势一致。[结果] 青藏高原EVI在2000—2010年以非显著变化为主，在栅格和保护区两个尺度上均表现为非显著增加样本多于非显著减少样本，青藏高原植被呈现整体好转局部退化的特征。[结论] 青藏高原保护区各项生态系统服务功能在2000—2010年以非显著变化为主，但生态系统服务功能非显著减少样本明显多于非显著增加样本，与EVI变化趋势不一致。

Abstract

[Objective] The response of the ecosystem service system to vegetation change in the Qinghai-Tibet Plateau conservation area from 2000 to 2010

and to further clarify the relationship between ecosystem services and remote sensing vegetation index were studied in order to provide a scientific reference for regional ecosystem service assessment and ecological protection.[Methods] This study focuses on various types of protected areas on the Tibetan Plateau and uses MODIS (moderate-resolution imaging spectroradiometer) EVI (enhanced vegetation index) products for vegetation change mapping. The ecosystem services such as carbon fixation

soil conservation

water conservation and habitat protection are used to determine the consistency of ecosystem services and EVI changes in the Qinghai-Tibetan Plateau conservation area from 2000 to 2010.[Results] The EVI of the Qinghai-Tibetan Plateau was dominated by non-significant changes from 2000 to 2010

and the non-significant increased samples were greater than the non-significantly decreased samples in both the grid and the protected areas

indicating that the vegetation on the Qinghai-Tibet Plateau is characterized by overall improvement and local degradation.[Conclusion] The ecological system services in the Qinghai-Tibet Plateau conservation area were mainly non-significant changes from 2000 to 2010

but the non-significant reduction samples of ecosystem services was significantly more than the non-significant increased samples

which was inconsistent with the change trend of EVI.
