摘要
香格里拉国家公园普达措片区位于“三江并流”世界自然遗产地核心区域,区内自然环境及多民族文化资源联系密切,对于景观多功能性研究具有典型性。研究明确了普达措片区景观多功能特征与演化情况,对研究区农业生产、景观文化、景观承载与调节服务中包含的11项景观功能进行评估,探索2006—2022年片区景观多功能性变化与权衡协同关系。结果表明:(1)普达措片区土地用途呈现多元化与生态化趋势,各类生态系统用地均衡发展。(2)区域景观多功能水平维持稳定,2006—2022年间片区的景观多功能水平均值为5.97,变化幅度约为1.67%。(3)各景观功能之间,“气候/体调节-碳固存”、“生物多样性-碳固存”与“生物多样性-生境质量”等功能间存在较为明显的协同关系,而“气候/体调节-粮食供给”、“气候/体调节-产水能力”及“气候/体调节-水质净化”等功能间存在明显的权衡关系。(4)普达措片区景观服务功能间的发展逐渐趋于协调。这表明普达措片区生态化管理对其景观多功能具有一定的积极作用,未来应当加强景观可持续性建设,促进片区及其周边社区“生产-生活-生态”功能协同发展。
The Pudacuo area of Shangri⁃La National Park is located in the core area of the“Three Parallel Rivers”World Natural Heritage Site.Its natural environment is closely connected with multi⁃ethnic cultural resources,and the study of landscape versatility is typical.After in⁃depth clarification of the multi⁃functional characteristics of the landscape in the Pudacuo area and its evolution process,this study conducted a comprehensive assessment of 11 landscape functions,including agricultural production,landscape culture,landscape bearing and regulation services,and explored the multi⁃functional changes and trade⁃off synergy of the landscape in Pudacuo area from 2006 to 2022.The survey results revealed:(1)The land use in the Pudacuo area shows a trend of diversification and ecologicalization,and the land use of various ecosystems is in a state of dynamic balance.(2)Between 2006 and 2022,the average value of landscape multifunctionality in the area was 5.97,with a change range of approximately 1.67%.(3)Among the landscape functions,“climate/body regulation⁃carbon sequestration”,“biodiversity⁃carbon sequestration”and“biodiversity⁃habitat quality”show a significant synergistic relationship,while“climate/body regulation⁃food supply”,“climate/body regulation⁃water production capacity”and“climate/body regulation⁃water purification”have obvious trade⁃off relationships.(4)The development of landscape service functions in Pudacuo area gradually becomes more harmonious.This confirms that ecological management of Pudacuo area has a positive effect on its landscape multifunctionality.For future development,it is recommended to further strengthen the sustainable construction of the landscape to promote the coordinated development of the“production⁃life⁃ecology”function in the area and its surrounding communities.
