青藏高原生态屏障区近十年生态环境变化及生态保护对策研究

从生态保护与管理的角度出发，综合分析了青藏高原生态屏障区近十年生态系统结构、服务功能、生态胁迫等生态环境变化特征，并提出生态保护对策与建议。结果表明，2000年－2010年屏障区生态系统结构稳定，其中城镇和湿地面积增加明显；生态系统服务功能整体上升，其中屏障区北部区域改善明显；生态胁迫以人口、GDP、载畜量等人类胁迫为主，自然胁迫整体较低；未来应继续加强基本草原保护，实施生态修复工程，不断提高屏障区的重要生态功能。

Ecological Environment Changes and Major Ecological Protection Countermeasures in Qinghai-Tibet Plateau Ecological Barrier Area During Recent Decade

From the perspective of ecological protection and management , the ecosystem structure and service and ecological stress were analyzed to study the ecological environmental changes , then the ecological protection countermeasures and suggestions were put forward.The results showed that the ecosystem structure was overall stable but the city and wetland area increased signifi-cantly.The ecosystem services improved and especially in the northern area;human stress such as population, GDP, grazing capac-ity was the main ecological stress while natural stress was respectively low .It's important to strengthen basic grassland protection , implement ecological restoration projects and improve the ecological function of Qinghai -Tibet Plateau Ecological Barrier Area .
