Abstract
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.
Highlights
As China’s urbanization process enters the middle- and later-phase of high-speed development, the conventional and extensive development mode can no longer meet the requirements in urban development
In the interview of index selection, the experts in the planning committee hope the complex system can be simplified and the simple indexes can be provided from the perspectives of urban decision-makers for the evaluation of regional environment resource carrying capacity
The integrated resource and environment carrying capacity evaluation started from the perspective of per capita environment and resource
Summary
As China’s urbanization process enters the middle- and later-phase of high-speed development, the conventional and extensive development mode can no longer meet the requirements in urban development. The implementation of double evaluations was helpful to maintain regional security and enhance the utilization efficiency of resources, thereby meeting the intensive and high-efficiency standards [2,3,4]. Since China proposed the planning scheme of the Huaihe River Eco-economic Belt, this region has become an important practice place for territorial space development due to its abundant and concentrated ecological resources and low land-use intensity [5,6]. This study improved the integrated evaluation index system of resource and environment carrying capacity by using the fuzzy analytical hierarchy process (FAHP) method and explained the judgement criterion of positive and negative indexes, which is expected to provide a reference for effective implementation of eco-economic spatial strategy in the Huaihe River Eco-economic Belt
