基于GIS技术的兴城市生态敏感度评价分析与规划策略

Ecological Sensitivity Evaluation Analysis and Planning Strategy of Xingcheng City Based on GIS Technology

摘要: 本文通过对生态敏感性进行评价分析，为城乡建设中划定生态红线、制定区域生态环境保护条例提供依据。文章以兴城市为研究区域，采用GIS空间分析技术，选取研究区域的高程、坡度、坡向和水文四大因子作为评价指标，对生态敏感区进行了等级分类，针对不同敏感区提出了相应的优化建议策略，为兴城市今后的生态规划设计提供参考和依据。结果表明：兴城市生态敏感度通过GIS的叠加分析，可以划分为不敏感区、轻度敏感区、中度敏感区、高度敏感区和极度敏感区五个层次。最后，根据不同的生态敏感度分区，提出分区治理方案和保护对策，以期为兴城市的环境保护规划提供技术支持和依据。

Abstract: Ecological sensitivity assessment and analysis are carried out to provide a basis for delineating ecological redlines and formulating regional ecological and environmental protection regulations in urban and rural construction. Taking Xingcheng City as the study area, GIS spatial analysis technology was used to select the four factors of elevation, slope, aspect, and hydrology of the study area as evaluation indexes, and the ecologically sensitive areas were classified into different levels, and corresponding optimization suggestions were put forward for different sensitive areas, which provided reference and basis for the future ecological planning and design of Xingcheng City. The results show that the ecological sensitivity of Xingcheng City can be divided into five levels: insensitive area, mildly sensitive area, moderately sensitive area, highly sensitive area and extremely sensitive area through GIS superposition analysis. Finally, according to the different ecological sensitivity zones, the zoning management scheme and protection countermeasures are proposed, in order to provide technical support and basis for the environmental protection planning of Xingcheng.
