基于生态敏感性的国土空间生态修复策略研究

Ecological Restoration Strategy of Land Space Based on Ecological Sensitivity

为了保护和改善生态环境,实现可持续发展,提出基于生态敏感性的国土空间生态修复策略。采集研究区域国土空间数据,将坡度、湿地、林地等生态因子拟作生态敏感性评估指标,通过生态源地、生态系统水平、景观阻力面、生态廊道推算生态敏感性分布格局。构建生态因子矢量图与属性表,采用加权求和法和空间叠加分析模型明确研究区域生态敏感性。测试结果表明,研究区域西南方向国土空间生态敏感度偏高,环境破坏较为严重,由此提出加生态修复策略,完善生态修复和环境污染治理,实现城市发展与自然生态之间的平衡。

In order to protect and improve the ecological environment and realize sustainable development,the ecological restoration strategy of land space based on ecological sensitivity is put forward.The land spatial data of the study area is collected by using the ecological factors such as slope,wetland and woodland as ecological sensitivity evaluation indicators.The distribution pattern of ecological sensitivity is calculated through ecological source,ecosystem level,landscape resistance surface and ecological corridor.The vector diagram and attribute table of ecological factors are constructed,and the regional ecological sensitivity is clearly studied by weighted summation method and spatial superposition analysis model.The test results show that the ecological sensitivity of the land space in the southwest of the study area is high,and the environmental damage is serious.Therefore,the strategy of ecological restoration is put forward to improve the ecological restoration and environmental pollution control,and realize the balance between urban development and natural ecology.
