Assessing the dynamic land utilization efficiency and relevant driving mechanism in in-situ urbanized rural areas: A case study of 1979 administrative villages in Hangzhou

Abstract

Rural revitalization is inseparable from the coordinated human-land relationship, and population-oriented land utilization efficiency is the most important manifestation of human-land interaction. Leveraging the diverse demographic migration patterns and adequate micro-scale units in in-situ urbanized rural areas, we firstly propose a dynamic land utilization efficiency indicator, which characterizes the intensification and coordination degree of human-land coupling simultaneously. Meanwhile, the intrinsic correlation among the rural residential land expansion, population flow and land utilization efficiency from the perspective of demographic migration is defined by Kaya identity and further quantitatively deconstructed by the Logarithmic Mean Divisia Index. The results demonstrate: only 24.4% of the villages are of intensive land utilization. The decreased land utilization efficiency under different demographic migration patterns represents similar proportions and differentiated intensities. It is found to occur in nearly 60% of both the villages with net population inflow and the villages with net population outflow. And the deterioration degree of land utilization efficiency in the former is generally significantly higher than that in the latter. While the villages with net population inflow present the better performance in the improvement of land utilization efficiency than that in the villages with net population outflow. The exploration will benefit rural sustainable development and provide effective inspiration for policymakers in rural revitalization.
