Which exerts a greater impact on ecosystem resilience: Cropland expansion or urban expansion? Insights from a spatiotemporal analysis
Ecosystem resilience (ER) is pivotal for regional ecological security and sustainable ecosystem development. Both cropland expansion and urban expansion impact ER; however, the comparative magnitude and spatial patterns of their effects remain underexplored. This study investigates the spatiotemporal evolution and distribution characteristics of ER in the Northern Slope Economic Belt of the Tianshan Mountains (NSEBTM) from 2000 to 2020, using Fragstats and ArcGIS. A combination of the Geo-informatic Tupu method, Zonal Statistics, and Standard Deviation Ellipse analysis was employed to assess and compare the positive (ecological adaptive expansion, EAE) and negative (ecological trade-off expansion, ETE) impacts of cropland and urban expansion on ER. ER levels in the NSEBTM remained low throughout the study period, with a turning point occurring in 2010, followed by gradual improvement. Spatially, ER exhibited a “northwest high, southeast low” distribution pattern, with high-value regions clustering in the northwest and low-value regions dispersing in the southeast. Both cropland and urban expansion exerted dual impacts on ER, with ETE effects dominating in the central and western areas and EAE effects prevailing in the eastern areas. Notably, cropland expansion had broader and more intense negative impacts on ER than urban expansion, with cropland changes affecting larger areas and exhibiting more pronounced ecological trade-offs. These findings highlight the need for sustainable land-use strategies that reconcile ecological preservation with the demands of agricultural and urban development.
期刊介绍:
The journal Ecological Informatics is devoted to the publication of high quality, peer-reviewed articles on all aspects of computational ecology, data science and biogeography. The scope of the journal takes into account the data-intensive nature of ecology, the growing capacity of information technology to access, harness and leverage complex data as well as the critical need for informing sustainable management in view of global environmental and climate change.
The nature of the journal is interdisciplinary at the crossover between ecology and informatics. It focuses on novel concepts and techniques for image- and genome-based monitoring and interpretation, sensor- and multimedia-based data acquisition, internet-based data archiving and sharing, data assimilation, modelling and prediction of ecological data.
