The evaluations of resource and environment carrying capacity and territorial development suitability, also referred to as “double evaluations”, have been taken by China as an important direction in territorial space planning. Based on the evaluation of resource and environment carrying capacity, the double evaluations can contribute to protecting ecological safety and territorial safety and promoting regional sustainable development. The focus of this study was to integratedly evaluate the resource and environment carrying capacity of the Huaihe River Ecological and Economic Belt. First, the overall weights of the factors at the dimension level and the index level in the established integration evaluation system were calculated with the fuzzy analytical hierarchy process (FAHP) method; and then, using the linear weighted function, the overall resource and environment carrying capacities of 25 cities in the belt were calculated. On that basis, the resource and environment carrying capacity evaluation model was established. Through model analysis, this study comprehensively investigated the resource and environment carrying capacity of the Huaihe River Eco-economic Belt and provided a foundation for the future territorial space planning and layout of the Huaihe River Eco-economic Belt.

Abstract In the Loess Plateau, natural resources are scarce and the ecological environment is fragile. Sustainable development requires special attention paid to resource and environmental carrying capacity (RECC). This paper selects 24 representative cities in five natural areas of the Loess Plateau, uses the entropy-weight-based TOPSIS method to evaluate and analyze the RECC of each city and region from 2013 to 2018, establishes a diagnosis model to identify the obstacle factors restricting the improvement of RECC and constructs the theoretical framework of RECC' system mechanism. Results show that the RECC of Loess Plateau is increasing in general but relatively small. The environmental and social subsystem have the highest and lowest carrying capacity respectively. There is an obvious contradiction between economic development and the environment. Population density, investment in technological innovation, per capita sown area of crops, and per capita water resources are the main obstacles affecting the improvement of RECC in the Loess Plateau. Such evaluation and diagnosis could support ecological civilization and sustainable development.

On the basis of the ecological carrying capacity connotation and to realize the coordinated development of economics and environment in Beijing mountainous valley areas, ecological carrying capacity evaluation was discussed in order to promote corresponding advice. The comprehensive evaluation index system was built which included ecosystem elasticity level，bearing capacity index and stress index of ecotourism. The comprehensive evaluation method was constructed. The score of ecosystem resilience of Lihuagou valley region in 2012 was 78.2, which was more stable. The score of carrying capacity of resource and environment was 71.2 which reached heavy level. The score of carrying capacity pressure was 53.3 which attained medium pressure. The score of carrying capacity system was 76.3 which was the second level. At last, this study promoted several corresponding advice.
