Resource Carrying Capacity Evaluation Based on Fuzzy Evaluation: Validation Using Karst Landscape Region in Southwest China

Abstract

The problems of regional resource shortage, fragile ecological environment and unbalanced social development are becoming increasingly serious. There is an urgent need for rational evaluation and planning of resources and the environment. This paper presents a fuzzy comprehensive evaluation method combined with Analytic Hierarchy Process (AHP) and shortcoming element evaluation to analyze the resource and environmental bearing capacity of a certain region. The proposed model was verified by backing data analysis from a karst landscape region in southwest China. Short board element analysis was employed for further study. The results show that (a) the calculation results of the evaluation system used in this paper are consistent with the actual situation. The method can be effectively used in the field of resource and environmental carrying capacity evaluation. (b) The environmental carrying capacity is the largest in this region, followed by the resource carrying capacity, and the socio-economic carrying capacity is the smallest. (c) The region has a sufficient environmental carrying capacity on the whole, the resource conditions are weak and the socio-economic development is backward. The analysis of the evaluation results provides a scientific basis for the rational use of resources, territorial spatial planning, sustainable socio-economic development and ecological environmental protection strategies in karst mountainous areas.

Application of Geographic Information System to Sensing Strength and Potentiality of Ecological Industrialization in China’s Huai River Ecological Economic Belt

“…Potentiality refers to the capability of an ecological economic zone to provide eco-friendly commodities and services through socialized, large-scale production and market-oriented management while maintaining the ecosystem balance. (13,22) In this context, potentiality is tightly linked to ecological endowment (9) and industrial endowment. (23) Ecological endowment, which is affected by the total and relative quantities of ecological resources, is the premise of ecological industrialization.…”

“…Ecological industrialization is an appropriate developmental path for ecological economic zones according to their ecological advantages. Although ecological industrialization has achieved remarkable construction results, (8) various problems have inevitably emerged, such as weak top-level design, (6) excessive or lagging development, (9,10) and imbalanced regional development. (11) The essential cause of the ecological industrialization construction problem is that managers and builders lack a clear grasp of its state and needs.…”

Assessing Waterway Carrying Capacity from a Multi-Benefit Synergistic Perspective

“…The current methods for quantitatively analyzing the WCC expose incapability and drawbacks in dealing with such issues. For example, the fuzzy comprehensive evaluation method, as a widely used method to deal with uncertainties and non-linearities in the evaluation of the carrying capacity, has a complexity of computation that is not friendly to users who do not have strong mathematical ability and have the drawbacks of excessive subjectivity in the se ing of the elemental weights [40,41]. In addition, a much-debated limitation of Bayes is that too much information is needed to construct a conditional probability table, which is nearly impossible to obtain in WCC assessments due to the complexity of the metrics at multiple scales.…”
