摘要:
基于生态安全提出了城乡非建设用地的概念,以平原河网地区佛山市为例,在GIS和RS等空间分析方法和数学模型的支撑下,从定量角度系统解析了快速城市化地区城乡非建设用地空间演变及对生态安全的影响。从整体生态环境质量来看,佛山市区域生态环境指数呈显著下降趋势,与城乡非建设用地的减少呈正相关性;从生态系统自身生态因子来看,水文效应表现为年均径流系数增大,地表温度表现为城市热岛效应增强,植被覆盖表现为大型森林斑块数量减少;从生态系统服务功能来看,表现为生态系统生态的服务层次和服务价值降低。
Abstract:
The concept of Urban and Rural Non-construction Land (URNL) is proposed based on ecological security in the paper. From a quantitative point of view, the paper systematically analyzes spatial evolution of URNCL and response of ecological security of Foshan City based on RS and GIS spatial analysis methods and mathematical models. In terms of the overall ecological environment quality, the regional ecological environmental index shows a significant downward trend and is positively correlated with the reduction of URNL. In terms of the ecological factors of the ecosystem, the runoff coefficient is increasing in the watershed, the area of strong urban heat island (UHI) is significantly increasing and sprawling, and the number of large-scale ecological patches is reducing. From the ecosystem services, the value of ecosystem service is dropping.
