基于生物多样性认知与评估的丽江市古城区城乡绿色空间规划策略研究

Urban-rural Green Space Planning Strategies Based on Biodiversity Cognition and Assessment: A Case Study of Lijiang Gucheng Area

摘要:

为从生物多样性保护视角出发进行绿色空间规划，探究生物多样性认知与评估的关系，运用MaxEnt 模型分析云南省丽江市古城区绿色空间的生物多样性分布格局，通过问卷调查公众对古城区生物多样性的认知，分析其影响因素。结果表明：生物多样性适生区集中分布于山地、湖泊和水库周围，呈现出“北低南高”的分布特征；公众对古城区生物多样性认知整体呈现出“两乡两镇较高，建成区内公园为认知最高点”的特征。通过空间自相关性分析可知，生物多样性分布指数与生物多样性认知指数在区域范围内呈负相关性，呈集聚的分布态势。基于研究结果，提出绿色空间优化、生物多样性认知提升、公众认知与实际生物多样性偏差区域规划3 个方面的古城区绿色空间规划策略。

Abstract:

To conduct green space planning from the perspective of biodiversity conservation andexplore the relationship between biodiversity cognition and assessment, this study used theMaxEnt model to analyze the biodiversity distribution in the green spaces of the GuchengArea in Lijiang City, Yunnan Province. Additionally, a questionnaire survey was conductedto investigate public cognition of biodiversity in the Gucheng Area and analyze the factorsinfluencing it. The results showed that the biodiversity suitable areas are concentratedaround mountains, lakes and reservoirs, presenting a distribution characteristic of lowerin the north and higher in the south; the public's overall cognition of biodiversity in theGucheng Area is characterized by higher levels in two townships and two towns, withurban parks in the built-up area as the cognition peak. Spatial autocorrelation analysisreveals that the biodiversity distribution index and the biodiversity cognition index exhibita negative correlation and an agglomerated distribution pattern across regional scales.Based on the research results, three strategies for green space planning in the GuchengArea were proposed, including green space optimization, biodiversity cognition promotion,and targeted planning for areas with deviations between public cognition and actualbiodiversity levels.
