摘要
针对现有城市绿地生态网络构建方法复杂多样、常用软件功能单一、规划支撑效果有限等问题,研发了城市绿地生态网络智能规划系统。将保护生物多样性、提升功能连接度作为城市尺度绿地生态网络构建的核心目标,统筹其他生态与社会服务功能,梳理和综合图论、生境质量评价、最小累积阻力模型和电路理论等生态网络模拟和分析方法,基于NET平台,采用ArcGIS Engine、C#、Python等技术,通过GIS二次开发方式实现系统各项功能,并以上海市闵行区为对象进行了实证分析。结果表明,系统可自动执行生态源地筛选、综合阻力面构建、生态廊道路径提取、生态廊道宽度确定、生态网络效能评价等技术环节,一键生成城市绿地生态网络布局结构,并实现不同情景的对比分析,为规划实践提供多情景、可视化的辅助决策。
An intelligent planning system for urban green space ecological network was developed to address the issues of diverse theoretical foundations,diverse technical processes,significant subjective impact,and limited support for planning in the construction of existing urban green space ecological networks.Protecting urban biodiversity and enhancing functional connectivity were taken as the core objectives of urban-scale green space ecological network construction,considering other social-ecological functions,we selectively and comprehensively incorporated several ecological network simulation and analysis methods,including graph theory,habitat quality assessment,minimum cumulative resistance model,and circuit theory.The system is built on the.NET platform and utilizes technologies such as ArcGIS Engine,C#and Python for component-based GIS development to implement various system functions.A case demonstration of the system was carried out in Minhang District of Shanghai.The system can automatically perform tasks such as ecological source area selection,comprehensive resistance surface construction,ecological corridor path extraction,ecological corridor width determination,and ecological network efficacy assessment.It can intelligently generate the layout structure of urban green space ecological network with a single click and perform spatial comparisons and balance analyses among different scenarios.This system can provide multi-scenario,visual auxiliary decision-making for planning practice.
