Spatial evolution of URNCL and response of ecological security: a case study on Foshan City

摘要

AbstractAs a global event, urbanization will bring long-term effects to the supporting systems and ecosystem services of the whole world. The concept of Urban and Rural Non-construction Land (URNCL) is proposed based on ecological security. It is a spatial response to facing the grand challenge of resources and environmental and a demand to achieve sustainable development in rapid urbanizing regions. The paper carries out quantificationally and systematically comprehensive research of spatial evolution of URNCL and response of ecological security of Foshan city (ecological factor and ecosystem service) based on integrating multiple data sources including remote sensing data, land-use classification data, relevant statistical data and field survey and monitoring data and introducing remote sensing analysis methods, geographic information systems spatial analysis methods and mathematical model methods.
