Scientific evaluation of the comprehensive carrying capacity of land is the condition for regional coordination and high-quality economic development. Applied entropy method and expert marking to determine weight, and adopted multi-objective comprehensive evaluation model to evaluate the comprehensive carrying capacity of land resources from 2008 to 2018 in Shandong province. The results show that the comprehensive carrying capacity level is located in the lower and intermediate critical level, which has obvious spatial differences, and carrying capacities of social economic, land resource, water resource and ecological environmental are not consistent. On this basis, according to obstacle characteristics of land comprehensive carrying capacity, puts forward the proposal for space optimization pattern.

Water resources carrying capacity is the maximum available water resources supporting by the social and economic development. Based on investigating and statisticing on the current situation of water resources in Shandong Province, this paper selects 13 factors including per capita water resources, water resources utilization, water supply modulus, rainfall, per capita GDP, population density, per capita water consumption, water consumption per million yuan, The water consumption of industrial output value, the agricultural output value of farmland, the irrigation rate of cultivated land, the water consumption rate of ecological environment and the forest coverage rate were used as the evaluation factors. Then,the fuzzy comprehensive evaluation model was used to analyze the water resources carrying capacity Force status evaluation. The results showed : The comprehensive evaluation results of water resources in Shandong Province were lower than 0.6 in 2001-2009 and higher than 0.6 in 2010-2015, which indicating that the water resources carrying capacity of Shandong Province has been improved.; In addition, most of the years a value of less than 0.6, individual years below 0.4, the interannual changes are relatively large, from that we can see the level of water resources is generally weak, the greater the interannual changes in Shandong Province.

The basic principle of matter element analysis theory was applied to establish the multi-level extensible evaluation model of advanced public transportation system. First, evaluation index system was established from three aspects, the transit technology level, economic benefit, social benefit and environmental impact. Then, according to the characteristics of evaluation indexes on different levels, entropy method and AHP was respectively used to determine the index weight value. Grade of evaluation was given by calculating relational degrees by layers. Finally, APTS in a city was studied as an example, and improvement measures were put forward. The method is proved to be reasonable and valid.

The water resources carrying capacity is an important component of natural resource carrying capacity in a country or region sustained development process. It is the key being related to using the water resources reasonably, which means vital to the sustained growth of the water resources, the social economy and the ecological environment concordant development.Taking the case of river basin in arid zone of the Manasi River Basin,The author evaluated water resources supporting capacity condition basin in different year of the Manasi River by establishing fuzzy comprehensive evaluation model. The results indicated that because of saving water technological progress and industry restructure advancement, the water resources carrying capacity of Manasi River will be improved in the future twenty years. The water resources supply and demand contradictory will be obtained certain alleviation, but the uneven of water resources space and time distribution is still the main restrictive factor of the development of society and economic and the ecological environment construction.

Quantitative research and evaluation of ecological carrying capacity in Qinghai Province is in line with the requirements of the 13th five-year plan, and is of practical significance to the construction of ecological civilization in Qinghai Province. Based on the PSR model, this paper constructs the evaluation index system of ecological carrying capacity from three aspects of pressure, state ,and response, uses the entropy method to determine the index weight coefficient, and comprehensively evaluates the changing trend of ecological carrying capacity since the 12th Five Year Plan of Qinghai Province from the perspectives of economy, society, resources, and environment. The results show that: from 2011 to 2019, the comprehensive evaluation of ecological carrying capacity in Qinghai Province shows a trend of first decreasing and then increasing, the response index evaluation increases greatly, the state index evaluation shows a fluctuating growth, and the pressure index is relatively stable. Based on this, the PSR model and entropy method are typical and quantifiable, which can provide a reference for Qinghai provincial government to control the ecological environment, study ecological sustainability and delimit the ecological red line.

As a key element in China’s spatial planning, the development zoning of land space has become a focus of China’s current activity. During its rapid social and economic development, China has faced severe and diverse challenges regarding sustainable development, such as farmland occupation, environmental degradation, urban land disorder expansion, etc. Against this backdrop, research on the linkage between resource–environmental carrying capacity (RECC) and the development zoning of land space in the process of sustainable development has received increased attention, and an accurate evaluation of the RECC would provide useful guidance for Chinese policy makers to carry out the development zoning of land space. This paper uses Henan Province as an example to construct a comprehensive evaluation model of “resource carrying capacity (RCC)–eco–environmental carrying capacity (EECC)–socio–economic carrying capacity (SECC)”, which calculates the level of RECC in a provincial area. In addition, this paper designs a correlation model between the RECC and the development zoning of land space, which uses a three-dimensional magic cube evaluation model to analyze the development zoning layout of land space. The results showed that a geographical pattern exists, where in the southwestern areas of Henan Province have a higher RECC than the central and northeastern areas. The results also indicated that the land space patterns of Henan Province can be divided into seven types of areas through a three-dimensional magic cube evaluation model, which can better reflect the spatial differentiation characteristics of the comprehensive index of RECC. The results of this study offer an important reference for policy-makers to make decisions and also provide a scientific and pragmatic basis for the formulation of sustainable development strategies.

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.
