Research on the Evaluation of Geological Environment Carrying Capacity Based on the AHP-CRITIC Empowerment Method

Abstract

In this study, two districts, Erdaojiang District and Dongchang District, in Tonghua City, Jilin Province, were evaluated for their geological environment carrying capacity. A total of 14 evaluation indicators were selected from the three aspects of the geological environment, ecological environment, and social environment to make it more comprehensive to evaluate the carrying capacity of the geological environment. Using the AHP and CRITIC methods, the subjective weight and objective weight of each evaluation index are obtained, and the combined weight is calculated by game theory. When combined with the GIS and combined weights, the distribution map of the geological environment carrying capacity is obtained, and it is classified into four grades: excellent, good, medium, and poor. A comprehensive evaluation of the carrying capacity of the geological environment is carried out. The following conclusions are drawn: the overall carrying capacity of the geological environment in the study area is good, and the carrying capacity of individual areas is poor. The comparative analysis of the good and poor areas provides a scientific basis for future environmental governance and urban planning and provides a scientific basis for geological disasters and mines.

Spray performance of flexible shield canopy opener and rotor wind integrated boom‐sprayer application in soybean: effects on droplet deposition distribution

“…The Criteria Importance Though Intercrieria Correlation (CRITIC) method is a quantitative analysis method based on the information contained in the data of the indicators themselves, and the weights of the indicators are calculated by mathematical deduction. The determination of weight coefficients of different indicators is based on two basic concepts: contrast strength and conflict 31 . Therefore, the CRITIC weighting method was used to determine the weights of the droplet uniformity indices on the adaxial and abaxial sides of the canopy leaves, followed by the establishment of a pesticide application efficiency evaluation model.…”

Resource and Environmental Carrying Capacity Assessment in Earthquake-Prone Area—Taking the Luding Earthquake Disaster as an Example

“…The resource and environmental carrying capacity refers to the ability of the resource and environmental systems to bear various social and economic activities while meeting the developmental needs and the relative stability of functions within a certain region (Wang et al, 2019; Wang et al, 2020; Qi et al, 2022). Research on resource and environmental carrying capacity evaluation has a developmental history in China that can be traced back to 1988 (Dang and Peng, 1988).…”

“…Research on resource and environmental carrying capacity evaluation has a developmental history in China that can be traced back to 1988 (Dang and Peng, 1988). Domestic research on resource and environmental carrying capacity has developed from single-factor evaluation to multi-factor and dynamic integrated evaluation, which are now more pluralistic and comprehensive than those of past years (Wang et al, 2019; Wang et al, 2020; Qi et al, 2022). Common evaluation methods for resource and environmental carrying capacity include the index system, footprint, and classical statistical methods (Zhang et al, 2018; Hsu et al, 2021).…”

Study on Stability Evaluation of Goaf Based on AHP and EWM—Taking the Northern New District of Liaoyuan City as an Example

“…Australia and Canada have a vast territory, a relatively small population, and a relatively sparse underground goaf distribution, so open -pit mining is feasible. However, compared with these countries, China has formed a large number of underground goaf in the mining process [11][12][13] , especially in the underground mines using open-pit mining. Since the 1980s, illegal mining has gradually emerged in China, leading to the existence of a large number of unknown underground goaf around the mines 14,15 .…”
