基于自然解决方案理念下的邛崃龙门山生物多样性博览园生态评估和修复概念规划

Evaluation and Ecological Restoration of Qionglai City Longmen Mountain Biodiversity Museum Based on Nature-based Solutions

基于自然解决方案(NbS)倡导通过修复退化生态系统,把保护和提升生物多样性作为关键目标,维持生态系统的稳定性。本文以龙门山生物多样性博览园概念规划为例,从水土流失、农业面源污染、生境质量多维角度系统评价现状基底,提出三大修复策略,重点考虑多样生境的营造,区分珍稀动物和常见优势动物生境,形成“一轴四廊四大分区”的生态结构,为博览园的分区规划、交通体系和产业体系等的布局提供生态支撑,进而维护区域生态安全。

Nature-based Solution(NbS)advocates the preservation and enhancement of biodiversity as a key objective to maintain ecosystem stability by restoring degraded ecosystems.Taking the conceptual design of Longmen Mountain Biodiversity Museum as an example,the thesis first evaluates the local ecological base according to soil erosion,agricultural non-point source pollution,habitat quality and other multidimensional parameters.It also proposes three main restoration strategies,which underline the creation of diverse habitats and the differentiation of common and rare animal habitats.In the end,a“one axis-four corridors-four partitions”ecological structure is formed,providing ecological supports for zoning system as well as traffic and industrial systems in order to maintain Longmen Mountain ecological security.
