Spatiotemporal Analysis and Control of Landscape Eco-Security at the Urban Fringe in Shrinking Resource Cities: A Case Study in Daqing, China.

摘要: As the main bearing area of ecological crisis in resource-rich cities, it is essential for urban fringe to enhance regional security during a city’s transformation. This paper takes Daqing City, largest oilfield China’s cold land, as an example. Based on remote sensing image data from 1980 2017, we use DPSIR (Driving forces, Pressure, State, Impact, Response) framework and spatial auto-correlation analysis methods assess analyze landscape eco-security change study area. From perspective time–space, partitioned, control strategies are proposed. The results demonstrate that: (1) changes mainly affected by exploitation protection policies; index declined 1980–2000 increased 2000–2017. (2) has obvious clustering characteristics, oil field warning. (3) determined 1692.07 km2, risk restoration 979.64 proposed partition strategies. expected provide new decision-making ideas order develop land management plans other resource shrinking cities.
