摘要

Rapid urbanization is fragmenting periurban cropland landscapes, increasing anthropogenic disturbance at cropland edges and heightening productivity sensitivity to climate extremes. Yet how micro-scale cropland edge interactions shape productivity adaptation to hydrological extremes remains unclear. By combining high-resolution modelling with a vulnerability–resilience assessment, we found that micro-scale cropland edge interactions are critical mediators amplifying the impacts of climate on productivity. A one-standard-deviation increase in cropland edge ratio increased log-transformed vulnerability to extremely dry events by 0.981 standard deviations, whereas a one-standard-deviation increase in ecological buffer zone ratio enhanced log-transformed resilience by 3.165 standard deviations. Counterfactual simulations identified two adaptation pathways: reducing cropland edge ratio and expanding ecological buffer zones. Across Shared Socioeconomic Pathways and Representative Concentration Pathways (SSP–RCP) scenarios, the Edge-Reduction strategy consistently decreased cropland edge exposure by nearly 36%, while the Buffer-Zone strategy expanded ecological buffer zones around cropland by 12–15% from 2020 to 2060. Our analysis underscores the role of cropland edge ratio in amplifying risks to cropland productivity during extremely dry events and provides a mechanistic framework for adaptive land management.
