Abstract
The evaluation of resource and environmental carrying capacity (RECC) is the foundation for the rationale behind the arrangement of land spaces for production, living, and ecological uses. In this study, based on various natural, economic, and social factors, an integrated Multi-Factor assessment model was developed to evaluate the RECC of Xinbei district of Changzhou. Meanwhile, we also calculated the population carrying capacity estimation model restricted by food security. The study comprehensively analyzed the current status and land resource characteristics of a rapid urbanization area and the RECC restrictions for protection and development. The results indicate that the comprehensive carrying capacity of Xinbei showed distinct spatial heterogeneity, with a decreasing trend from the riverside protection area to urban areas, then to mountain areas. Combined with the secure food supply provided by future land resources, it was estimated that the population carrying index of Xinbei would be as high as 1.25 and 1.22 in 2035 and 2050, respectively, indicating that both years would experience a population overload. Therefore, an urgent adjustment to the structure and layout of territorial space and resources of the Xinbei District is necessary.

Summary
Policy has led to a series of problems, such as rapid population growth, ecological environment degradation, traffic congestion, and resource shortage, causing a serious conflict between economic and social development, and the resources and environment [1,2,3]. A series of challenging problems concerning how to coordinate the relationship between resources, environment, ecology, social and economic development, and how to facilitate sustainable and green development of a regional economy based on source and environmental conditions has emerged [4,5]. A comprehensive understanding of the local conditions and the biophysical limits of the environment and the environment carrying capacity (ECC) is crucial for the overall arrangements of the planning and construction of territorial space [6,7]. In China, Zeng (1998) first made comprehensive environmental research in
