Abstract: The coastal area of northern Jiangsu (CNJ) is the largest silt coastal zone along the western Pacific Coast. This area is a newly established world natural heritage site and is also the largest winter habitat for the red-crowned crane in the world. However, rapid economic development in the study area has led to great changes in the types and intensities of land-use, which has had an effect on the distribution of wintering red-crowned cranes. In this paper, we first analyzed land-use change and determined the spatiotemporal evolution of land-use types and intensities in the study area. Then, the distribution of the red-crowned cranes was analyzed over various years. Finally, a geographically weighted regression (GWR) model was adopted to study the spatial differences in the effects of land-use types and intensity changes on the distribution of the cranes. The results showed that salt marsh (p<0.01), salt field (p<0.05) and paddy field (p<0.05) were positively correlated with red-crowned cranes. Dry land (p<0.05), construction land (p<0.01) and aquaculture pond (p<0.05) were negatively correlated with red-crowned cranes. There was a strongly negative correlation between land-use intensity and the red-crowned cranes (p<0.01). These positive and negative factors had significant spatial heterogeneity. Given these differences and the current local economic and land policies, we proposed the concrete countermeasures for red-crowned crane habitat protection and established a “friendly” land-use pattern that is beneficial for the protection of the crane population and restoration of its habitat.
