Northeast China is an important ecological barrier and commodity grain base in China. The coupling coordination relationship between geology–geomorphology and ecology has become a critical background condition for ecosystem protection and sustainable development. Taking Northeast China as a case (accounting for about 13% of China’s land area), 9 divisions are divided according to the characteristics of regional ecology and geology–geomorphology, and 17 indicators are selected to build an evaluation index system. Methods of analytic hierarchy process, entropy weight and game theory are used to determine the index weights. Based on the coupling coordination degree (CCD) model, the spatial coupling coordination characteristics of geology–geomorphology and ecology are studied. The variation characteristics of the Normalized Difference Vegetation Index (NDVI) are evaluated by Sen+Mann–Kendall (Sen+MK) method. Our results are as follows. (1) The coupling between geology–geomorphology and ecology is strong, but the spatial differentiation of CCD is obvious. Nine divisions are evaluated as two high–level, three medium–level and three low–level coordination types and one mild imbalance type. (2) The plain divisions Ⅰ and Ⅳ where the typical black soil belt is located are high coordination types. Restricted by geology–geomorphological conditions or ecological conditions, mountain divisions Ⅲ and Ⅶ and plain division Ⅴ are moderate coordination types, mountain divisions Ⅱ and Ⅷ and plateau division Ⅸ are low coordination types, and mountain division Ⅵ is mild imbalance type. (3) The variation trend of NDVI shows a significant increase in divisions Ⅲ, Ⅴ, Ⅰ, Ⅱ and Ⅶ. it shows a significant decrease in part of divisions Ⅳ, Ⅵ, Ⅷ and Ⅸ, and ecological management and construction should be strengthened in these divisions. The research shows that the CCD model method is feasible for evaluating the relationship between geology–geomorphology and ecology and can provide eco–geological background information for Northeast China.

“…Based on the above principles, as well as previously proposed governance standards for subsidence areas [42,43], and considering the principle of maximizing economic benefits, we selected five indicators for our evaluations and analyses: the geographic location of the subsidence area, the NDWI, the FVC, the maximum subsidence depth, and the maximum sinking area.…”

AHP-EWM Based Model Selection System for Subsidence Area Research

et al. 2023

Coal mining can create a variety of environmental, ecological, and land-use problems. Subsidence areas resulting from coal mining are a common and particularly difficult problem to manage. Despite much discussion in the academic literature as well as among local and international stakeholders, there is neither a uniform standard nor a universally accepted approach for selecting an appropriate governance model for a subsidence area. In particular, the lack of quantitative evaluation methods and excessive subjectivity represent key obstacles to the effective selection of governance models for subsidence areas. This paper proposes a selection framework for a coal mining subsidence governance model that integrates the analytic hierarchy process (AHP) and entropy weight method (EWM). The model comprehensively considers the settlement characteristics of the subsidence area, its geographic location, the water index, as well as the vegetation index. These variables are used as indicators to develop an evaluation framework upon which different subsidence zones can be quantitatively analyzed. The selection framework is demonstrated using examples from three subsidence areas in the Huainan and Huaibei mining areas in China, for which relevant data were collected and processed with the help of field surveys, remote sensing images, and subsidence prediction software. Applying the novel selection framework, the most suitable governance model for each subsidence area was obtained and determined to be consistent with the recommendations of an academic panel composed of multiple experts. The novel selection framework has high efficacy and potential to overcome the problem of subjectivity in the selection of governance models for coal mining subsidence areas. It is also envisaged that future incorporation of the selection framework into a user-friendly software package will significantly improve the efficiency with which suitable governance models for coal mining subsidence areas are selected.

“…When pollutants exceed the water's self-purification capacity, it can cause changes in water color and odor. Especially when the organic pollutants and ammonia nitrogen exceed the standard, the water will be eutrophicated, resulting in the death of organisms and the destruction of the population structure [16][17][18]. Therefore, the selected indicators for evaluating water quality are ammonia nitrogen (NH3-N), dissolved oxygen, and chemical oxygen demand…”

The purpose is to comprehensively evaluate the health status of the water resources of the Futuan River in Rizhao City. According to the natural and social service functions of the river, combined with the actual situation of the water resources of the Futuan River, an indicator system of comprehensive river health evaluation is constructed. Firstly, the application of 5G technology in ecological environment detection is introduced. Secondly, an indicator system for river health assessment is constructed from five aspects: hydrology and water resources, water quality, aquatic organisms, physical structure, and social service function. The fuzzy analytic hierarchy process (FAHP) is used to determine the membership degrees of the indicators to different health levels, and the comprehensive health value of the river is comprehensively determined. Finally, the groundwater quality of Futuan River is estimated, the balance of water supply and demand is analyzed, and the health of Futuan River in Rizhao City is evaluated. The results show that the total hardness of groundwater in Futuan River ranges from 30.26 to 5065.24 mg/L, and the average value is 370.02 mg/L. The pH range is 6-7.5 with an average of 6.9, and the TDS range is 90.13-26609.24 mg/L with an average of 831.32 mg/L. The Futuan River has a score of 0.67 for river health, which is in a critical state. The overall scores of hydrology, water quality, and aquatic organisms are 0.64, 0.77, and 0.63, respectively. The health level of these three is also in a critical state. The physical structure has a score of 0.51, and its health rating is in poor condition. The score of social service function is 0.64, and its health level is in the subhealth state. This research provides an idea for the management and restoration of the Futuan River in Rizhao City.
