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.

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.

Terrestrial ecosystems provide a variety of benefits for human life and production, and are a key link for achieving sustainable development goals (SDGs). The basin ecosystem is one type of terrestrial ecosystem. Ecological security (ES) assessments are an important component of the overall strategy to achieve regional sustainable development. The Huaihe River Basin (HRB) has the common characteristics of most basins, such as high population density, a rapidly developing economy, and many environmental problems. This study constructed an ES evaluation system by applying a pressure-state-response framework as an assessment method for the sustainable development of basins. Taking the HRB as an example, this study determined the ES status of the region from 2001 to 2019 and analyzed crucial factors for any variation observed by combining remote sensing and climate data, relevant policies, and spatial information technology. The results highlight the importance of reserves and the negative impact of urban expansion on ES. Additionally, the enactment of policies had a positive impact on ES, whereas precipitation had a negative effect on ES in most areas of the HRB. Based on these results, the government should strengthen the protection of forests, grasslands, and wetlands and improve water conservation facilities. This study provides guidance for the subsequent economic development, environmental protection, and the achievements of SDG 15 in the HRB.

Today’s ports have become an important node in the global supply chain. It is particularly important to make a scientific assessment of the comprehensive capabilities of the port and to provide a reference for the long-term development of the port. From the perspective of the supply chain, this article first selects the evaluation indicators that affect the port’s capabilities from four aspects of port resource ownership, control management, comprehensive services, and innovation-driven aspect. Secondly, we use the expert scoring method to judge the importance of the evaluation indicators and build a scientific and independent port capacity evaluation system from the perspective of the supply chain. Then, this paper uses the analytic hierarchy process to determine the weight coefficients of each evaluation index and uses the gray cluster analysis method of the triangular whitening weight function based on the center point to establish a qualitative and quantitative port capacity evaluation model from the perspective of the supply chain. Finally, we take a port in Northeast Asia as an example to conduct an empirical analysis to verify the feasibility of the port capacity evaluation system and model from the perspective of the supply chain constructed in this paper. The research results of this article can well analyze the port’s resource ownership, control and management capabilities, comprehensive service capabilities, and innovation-driven capabilities and provide a practical and effective theoretical basis for the port’s key development directions.

In the construction plan of the Xi'an-Xianyang Integration, water resources carrying capacity (WRBC) plays an important role in construction planning. Establish a comprehensive evaluation model of water resources carrying capacity in Xianyang City. 10 indexes of 5 categories, which were selected the analysis of relevant indexes including socio-economic indexes, water supply and demand indicators and water quality indicators, etc., were used to composing evaluation system. Using Cluster Analysis, Analytic Hierarchy Process (AHP) and Fuzzy Matrix. The sum of insecurity and less security coefficient of Xianyang City Water Resources Carrying Capacity is at about 0.7. The sum of more security and security coefficient is at about 0.3. And the safety coefficient of Water Resources Carrying Capacity in Xianyang City shows increasing trend. In Xi'an-Xianyang integration, through economic development, focusing on the construction of water and water pollution control, water resources carrying capacity is expected to increase in Xianyang City.

Most evaluation systems don’t consider the problem of evaluation index selection, so the evaluation delay increases, and the evaluation results are not ideal, in order to solve the above problems effectively, a system to evaluate the water resources environmental carrying capacity in island tourism based on frequency analysis method is proposed and constructed. Through the study of the concept and connotation of water resources environmental carrying capacity in island tourism, combined with the system analysis theory, the principle of comprehensive evaluation indicator selection is established; the basic indicators are screened by frequency analysis method, and the evaluation system of water resources environmental carrying capacity in island tourism is established. According to the established system, a comprehensive evaluation model is set up to evaluate the environmental carrying capacity of water resources in island tourism. The simulation results show that the proposed system can effectively reduce the delay and improve the accuracy of the results to evaluate the environmental carrying capacity of water resources in island tourism.

This paper established the comprehensive evaluation system of urban land intensive use from land use investment and output benefit, land use intensity and land use ecological benefit etc. Based onthe statistical data of land use, using principal component analysis, this paper made comprehensive evaluation on the intensive land-use level of 17 cities in Anhui Province from 2004 to 2009 , analyzed the changing situation in space and time. The results showed: (1)The level of urban land intensive use of Anhui Province constantly improved from 2004 to 2009, increasing more than 2 times of the intensive land-use level; (2)the level of urban land intensive use had significant regional differences, the south of the Huaihe River cities having the higher level, and the north of the Huaihe River cities having the lower level; (3)economic development level is the most important external factor affecting the level of urban land intensive use. The level of urban land intensive use is higher in developed areas, such as Hefei , Ma Anshan and Wuhu than other areas.
