摘要
沼泽湿地在维护区域生态安全和生态平衡发挥着至关重要的作用.云南省沼泽湿地面积共40 578.94 hm2,主要分布于迪庆州、丽江市、昭通市,3个州市合计占全省沼泽湿地面积的77.33％.长江流域是云南沼泽湿地的主要分布区,占全省沼泽湿地总面积的79.06％.海拔在3 000m以上的高山亚高山沼泽湿地占全省沼泽湿地总面积的74.48％.云南省沼泽湿地资源保护率达70.85％,但沼泽湿地生态系统相对脆弱,面临着重要性认识不足、系统性修复不强以及管理协作机制不健全等问题.建议从沼泽湿地保护、修复、科研监测和管护等方面加强云南省沼泽湿地的保护工作.
Abstract
Marsh wetlands play a crucial role in maintaining regional ecological safety and ecological balance.The total area of marsh wetlands in Yunnan province is 40 578.94 hm2,primarily distributed in Diqing prefecture,Lijiang city,and Zhaotong city.The combined area of these three prefectures accounts for 77.33％of the province's total marsh wetlands.The Yangtze River basin serves as the primary distribution area for marsh wetlands,covering 79.06％of the province's total area.Alpine and subalpine marsh wetlands,locates at altitudes above 3 000 meters,constitute 74.48％of the total marsh wetland area in Yunnan province,amounting to 30 222.77 hm2.Although the protection rate of marsh wetland resources in Yunnan province is 70.85％,the ecosystem is relatively fragile,facing challenges such as insufficient awareness of its importance,weak systematic restoration efforts,and an inadequate collaborative management mechanism.Therefore,it is recommended to strengthen the protection of marsh wetlands in Yunnan province through comprehensive measures,including marsh wetlands conservation,restoration,scientific monitoring,and management.
