摘要:

土地利用变化是生物多样性与生态系统服务变化的主要原因之一。评估土地利用变化对生物多样与生态系统服务影响对于政府决策具有重要作用。钱江源国家公园体制试点区是钱塘江的源头, 也是国家的重点生态功能区。本研究以钱江源国家公园体制试点区为研究区, 首先设计自然发展情景、规划情景、生态保护情景和开发利用情景等4种2025年不同土地利用变化情景, 随后采用InVEST模型和CLUE-S模型分析不同情景下钱江源国家公园水资源供给、涵养水源、固碳释氧、土壤保持、环境净化和生境质量等生态系统服务及其价值变化。结果表明: (1)核心保护区和生态保育区的生态系统服务价值占钱江源国家公园总价值的88.30%。(2)生态保护情景下钱江源国家公园生态系统服务价值最高, 有129.17亿元; 规划情景下生态系统服务价值次之, 有126.92亿元。(3)规划情景下钱江源国家公园水资源供给服务优于生态保护情景, 其他生态系统服务则次于生态保护情景。考虑到钱江源国家公园为下游提供重要的水资源这一功能, 将规划情景作为试点区2025年最优的土地利用变化情景。

Abstract:

Land use change is one of the main drivers to change of biodiversity and ecosystem services. It is important for decision-making of government to assess impacts of land use change on biodiversity and ecosystem service. The Qianjiangyuan National Park pilot (QNPP), located at the headwaters of the Qiangtang River, covers 252 km 2, and it is also a National Key Ecological Function Zone. In this study, We designed four land use change scenarios in 2025 for QNPP, i.e., business as usual, strategic planning, ecological protection, and development. Furthermore, the change in ecosystem services and its value in QNPP were evaluated under four scenarios by InVEST (Integrated Valuation of Ecosystem Services and Trade-offs) model and CLUE-S (Conversions of Land Use and its Effects at Small Regional Extent) model. The ecosystem services in this assessment include water yield, water conservation, carbon sequestration and oxygen release, soil conservation, environmental purification, and habitat quality. Our results show that: (1) the value of ecosystem services in core protected areas and ecological conservation areas accounts for 88.30% of total value of QNPP; (2) the value of ecosystem services of QNPP in the ecological protection scenario is the highest (12.917 billion RMB yuan), and ranks the second in the strategic planning scenario (12.692 billion RMB yuan); and (3) the water yield in the strategic planning scenario is superior to that in the ecological protection scenario, while other ecosystem services are inferior to that in the ecological protection scenario. Strategic planning scenario is an optimal land use strategy in 2025 since QNPP play a key role in providing water resources for the downstream.
