In order to clarify the comprehensive operational capabilities of the airport and better plan the sustainable development mode of the airport, this paper studies the evaluation method of airport environmental carrying capacity. First, this paper proposes the concept of airport environmental carrying capacity by taking into account the complex characteristics of airports affected by multiple factors and then selects 16 representative evaluation indicators to construct an indicator system based on the Driving Force-Pressure-State-Response (DPSR) framework. Finally, the accelerated genetic algorithm-projection pursuit model is established to model a comprehensive evaluation index, which is used to calculate the airport environmental carrying capacity (AECC). The results of the case study show that the AECC of Guangzhou Baiyun International Airport (CAN) decreased year by year from 2008 to 2017, which is in line with the coordinated development level of CAN. By analysing the changing mechanism of AECC and indicators, we get 6 key influencing indicators that led to the continuous decline of AECC and put forward some political suggestions to improve the AECC.

Eco-environmental carrying capacity of water comprehensively representing the resource and eco-environmental characteristics of water determines the carrying ability of nature ecosystem for socio-economic development. Fushun and Tieling section are chosen as upstream in Liao River Basin to compare the eco-environmental carrying capacity of these two water stream. In this paper, 11 indexes are selected to establish evaluating indicator system, and then use the fuzzy comprehensive evaluation method to calculate eco-environmental carrying capacity of water. Result demonstrated: the score value of water eco-environmental carrying capacity of Fushun section is greater than that of Tieling. The little advance of water eco-environmental carrying capacity of Fushun was due to its better nature eco-environment.

It is of great significance to establish a scientific and reasonable water resources carrying capacity evaluation system and evaluation method on the basis of studying the interdependence and mutual relations of water resources, society, economy and the ecological environment. This can guide water resources utilization and economic and social development planning, and promote the sustainable development of water resources and the socio-economic system. Projection pursuit technology can achieve automatic index selection and index weight confirmation. When used to assess water resources carrying capacity, the subjectivity and uncertainty of index weights can be avoided. Meanwhile, it can also be used to optimize the index system, and can improve the accuracy of evaluation results and discrimination. In this paper, the projection pursuit grade model of water resources carrying capacity is established. The evaluation criteria are determined by combining the theory with practice. Grades I to IV indicate that the water resources capacity declines gradually. This is the first study of water resources carrying capacity in four municipalities in China. The results show that the water resources carrying capacity of the four municipalities in 2012 belong to the third level, Chongqing is close to the second level and Tianjin is close to the fourth level.

Abstract Rare earth is a non-renewable and important strategic resource, and China is rich in rare earth resources. However, the process of massive exploitation has caused the migration, diffusion transformation and accumulation of pollution sources, which in turn has a profound impact on the ecological environment of mining areas. Accurate evaluation of resource and environmental carrying capacity (RECC) is important for the green development of mining areas. In this paper, the fuzzy comprehensive evaluation method based on AHP and entropy combination assignment method is used to study the RECC of mine area in terms of both support capacity and pressure. The Bayan Obo mine in Inner Mongolia; Longnan mine in Jiangxi; Weishan mine in Shandong; Mianning mine in Sichuan; Pingyuan mine in Guangdong; and Chongzuo mine in Guangxi, which have typical representatives, were selected for the horizontal comparison. The results show that, with the exception of Bayan Obo, the support index is greater than the pressure from mining and human activities in all the mining areas. The RECC index ranks for each mining area were: Bayan Obo > Longnan > Mianning > Pingyuan > Weishan > Chongzuo. In addition, an obstacle degree model was used to identify and extract the main factors affecting the ecological quality of the mine site. The ratio of investment in environmental pollution control to GDP is the most important factor limiting the improvement of the mine support index. The results of this paper were given for the different evolutionary processes and differences of RECC in typical rare earth mining areas, which could provide valuable references for achieving the green and comprehensive development of rare earth industry.

Scientific assessment of tourism environmental carrying capacity is key to geotourism sustainable development. Based on exploring the definition of tourism environmental carrying capacity of geoparks and its characteristics, by adopting methods of AHP and literature review this paper focuses on establishing an appraisal indicator system of tourism environmental carrying capacity of geoparks. However, its more reasonable to give weights of appraisal indicators for a given geopark for geoparks greatly differ in terms of natural, economical and socio-cultural environment. Thus, taking Xinwen Karst World Geopark in Sichuan province as an example, the paper calculates weights of indicators of the parks tourism carrying capacity with AHP method and measures its tourism environmental carrying capacity by using average weighted method. The findings reveal that Xinwen Karst World Geopark is in mild overloading.

This paper introduced the idea of environmental carrying capacity (ECC) to the planning of watershed’s environmental-economic optimization. And a case study in Lake Fuxianhu is utilized from year 2008 to 2028. The results are: based on the water environment carrying capacity of lakes, with the adjustment of industrial internal structure, distribution and development speed of three major industries, the water quality of the basin will be I class. This adjustment will not only keep a rapid development of economy, but also can make sure the improvement of Lake Fuxianhu Basin environment. Thus, the development of society and environment will be coordinated. The application of water environment carrying capacity of lakes to instruct the scale of social development is very significant to the sustainable development among economy, society and environment.

Airport environmental carrying capacity (AECC) provides the fundamental conditions for airport development and operation activities. The prediction of AECC is a necessary condition for planning an appropriate development mode for the airport. This paper studies the dynamic prediction method of the AECC to explore the development characteristics of AECC in different airports. Based on the driving force-pressure-state-response (DPSR) framework, the method selects 17 main variables from economic, social, environmental and operational dimensions, and then combines the drawing of causal loop diagrams and the establishment of system flow diagrams to construct the system dynamics (SD) model of AECC. The predicted values of AECC are obtained through SD model simulation and accelerated genetic algorithm projection pursuit (AGA-PP) model calculation. Considering sustainable development needs, different scenarios are set to analyze the appropriate development mode of the airport. The case study of the Pearl River Delta airports resulted in two main conclusions. First, in the same economic zone, different airports with similar aircraft movements have similar development characteristics of AECC. Second, the appropriate development modes for different airports are different, and the appropriate development modes for the airport in different periods are also different. The case study also proves that the AECC prediction based on SD model and AGA-PP model can realize short-term policy formulation and long-term planning for the airport development mode, and provide decision-making support for relevant departments of airport.

According to the characteristics of human resources managers’ competency and the research of relevant literatures at home and abroad, a competency evaluation method of human resources managers based on multi-granularity linguistic variables and VIKOR method is proposed. Firstly, the evaluation indicator system based on the competency of human resources managers is constructed. Then, by converting the evaluation information of different experts in different granularity to the same granularity by two-semantics, the comprehensive evaluation values can be obtained by integrating information of different experts. Further, the objective weights of the evaluation indexes were determined by the entropy method and an evaluation method were proposed based on the VIKOR method. Finally, an application example is given to illustrate the evaluation procedures of the developed approach and to demonstrate their practicality and effectiveness.
