中新社西宁11月21日电 (潘雨洁)三江源国家公园管理局21日在青海省西宁市召开新闻发布会。会上发布，五年来，三江源国家公园生态系统功能持续好转，多样性、稳定性、持续性不断提升。
三江源国家公园位于青藏高原腹地、青海省西南部，面积19.07万平方公里，平均海拔超过4700米，是长江、黄河、澜沧江发源地，是高寒生态系统的典型代表、高寒生物种质资源库。三江源国家公园试点至今已10年、正式设园4年，为中国面积最大、海拔最高的国家公园。
相关评估结果显示，五年来，三江源国家公园草地植被综合覆盖度为36.8%，比试点前增加8.6%；水源涵养服务能力指数为92.6，比试点前增加21.8；湖泊面积整体扩张，大于30平方公里的典型湖泊总面积近6000平方公里；降水量较多年平均偏多16.6%，地表水资源量较多年平均偏多33.7%，每年为下游提供900亿立方米的源头活水。
同时，三江源国家公园加强生物多样性保护研究，陆生野生动物种群持续恢复，藏羚由濒危降为近危，雪豹由濒危降为易危，兔狲、藏狐、白唇鹿、野牦牛频频现身；黑颈鹤、金雕、大鵟、猎隼、胡兀鹫翱翔蓝天；水域水生生物基本处于原始状态，保存相对完整，未遭人为破坏。(完)
