摘要: Many cities in Mollisol (black earth) regions need to revitalize their local economies while avoiding excessive farmland consumption, which could have a global impact. To resolve this dilemma, we have to understand how urbanization interacts with farmland loss, which requires factoring in their interconnected influences. The Chicago urban agglomeration (CUA), Harbin−Changchun urban agglomeration (HCUA) and Dnipro−Kamianske urban agglomeration (DKUA) were selected to compare farmland loss in relation to urban morphology, growth patterns and networked cities during 2000–2020. Our results show that trends in farmland loss can be differentiated between individual cities, and also controlled via their interconnections. Overall, expansion of CUA and DKUA has decelerated but HCUA is still undergoing rapid urbanization, with its area increasing by 116 %. Urbanization pressure has shifted from core cities to small and medium-sized cities, which have also experienced directional farmland loss, towards their influential neighbors. Farmland loss disparities between different intra- and inter-UA subgroups are prominent, demonstrating that occupation pressure is diverse and phased in a UA, and cannot be addressed by a one-size-fits-all form of zoning control. These findings support the conservation and protection of fertile soils from urbanization pressure, and promote international cooperation between global Mollisol regions.
