摘要
随着中国城市化进程的加快，许多城市都受到了负面影响。本项目重点保护南京紫青的生态环境，应用地理信息系统（GIS）加强生态保护和解决环境问题。GIS可以汇总、分析和可视化空间数据，是生态敏感区（ESA）选择过程中可用的工具之一。生态敏感性是指生态系统对人类活动和自然环境变化的响应程度，反映了区域范围内出现生态问题的可能性。本研究通过模型构建和因子选择来评估紫青的生态敏感性。本研究探讨了GIS中分类和数据处理的当前应用，以及空间分析在选址和微气候改善中的潜力。该项目将生态和基础设施指标应用于生态敏感性评估，从因子选择到生态敏感性分区评估。它结合了德尔菲法、层次分析法和叠加法等多种方法。通过分析，对紫青地区景观环境现状进行多维度的评价，为今后的保护和发展提供依据。

Abstract
With the acceleration of urbanization in China, many cities are subjected to negative impacts. This project focuses on protecting the ecological environment of Ziqing in Nanjing by applying Geographic Information System (GIS) to enhance ecological protection and address environmental issues. GIS can aggregate, analyze, and visualize spatial data, serving as one of the tools available during the selection process for Ecologically Sensitive Areas (ESAs). Ecological sensitivity refers to the extent to which ecosystems respond to human activities and changes in the natural environment, reflecting the likelihood of ecological problems arising at a regional scale. In this study, the ecological sensitivity of Ziqing is evaluated through model construction and factor selection. This research explores the current applications of classification and data processing in GIS, as well as the potential of spatial analysis in site selection and microclimate improvement. The project applies both ecological and infrastructural indicators in the evaluation of ecological sensitivity, from factor selection to the assessment of ecological sensitivity zoning. It combines various methods such as the Delphi Method, Analytic Hierarchy Process, and Overlaying Analysis to provide a multi-dimensional evaluation of the landscape environment in Ziqing, offering a basis for future protection and development efforts.
Key words： Urbanization; Ecologically Sensitive Areas (ESAs); Multi-dimensional Methods; Geographic Information System (GIS)
