中文摘要: |
高寒草甸是云南省主要草原资源之一,集中分布在滇、川、藏三省交界处的三江并流重要生态区,研究高寒草甸分布规律及生态系统服务价值有重要意义。根据云南省草原基况监测和年度林草生态综合监测成果,云南省高寒草甸面积100 775.50 hm2,占现状草原总面积的7.7%,其中迪庆
州高寒草甸面积77 776.18 hm2,占高寒草甸总面积的77.18%;主要利用方式为自然保护和暖季放
牧,占比分别为36.20%和33.09%;生态系统服务价值总量为41.86 亿元/a,单位面积价值量为
4.15 万元/(hm2·a)。受过度放牧的影响,高寒草甸存在不同程度的退化,推行适度放牧和高质量生态修复是提高其生态系统服务价值的有效手段。 |
英文摘要: |
Alpine meadows are one of the major grassland resources in Yunnan Province, primarily concentrated
in the ecologically significant Three Parallel Rivers region at the junction of Yunnan, Sichuan,
and Tibet. Studying their distribution patterns and ecosystem service value is of great importance. Based
on grassland monitoring data and comprehensive annual forest-grassland ecological surveys in Yunnan,
the total area of alpine meadows in the province is 100 775.50 hm2, accounting for 7.7% of the current
grassland area. Among this, Diqing Prefecture contains 77 776. 18 hm2 of alpine meadows, making up
77.18% of the total. The primary land-use types are nature conservation(36.20%) and warm-season
grazing(33.09%). The total ecosystem service value is estimated at 4.186 billion CNY/year, with a perunit
area value of 41 500 CNY/ hm2·year. Due to overgrazing, alpine meadows exhibit varying degrees
of degradation. Implementing moderate grazing and high-quality ecological restoration are effective measures
to enhance their ecosystem service value. |
