Ecological Carrying Capacity

To improve the ecological footprint model in aspect of reflecting sustainability of the economic, social and technological, the emergy analysis and socio-economic system development index were introduced into the model. The modified ecological footprint model was applied in the calculation of ecological carrying capacity and ecological footprint in Tibet, China. The ecological carrying capacity/cap is 19.13hm2, and the ecological footprint/cap is 8.96hm2. The result shows that the Tibet region is under the condition of ecological surplus and it is suitable for further programs development to some extent. But the high proportion of energy resources, cement and fertilizer utility should draw attention during the exploitation or construction progress.

Under the concept of green development, accurately mapping ecological carrying capacity to effectively evaluate regional sustainability has already become an important issue in China. This study introduced ecological carrying capacity intensity (ECintensity) based on the revised three-dimensional ecological footprint (3DEF) model to describe the temporal–spatial patterns of three-dimensional ecological carrying capacity (EC3D) in Inner Mongolia in 2010–2016 and to explore factors affecting socioeconomic sustainable development. The results showed that ecological footprint size (EFsize) differed between cities/leagues but changed little during the study period. Ecological footprint depth (EFdepth) far exceeded the original value of 1.00. Ecological carrying capacity (EC) varied in cities/leagues, while ECintensity increased slowly with stronger potential for regional development. Three-dimensional ecological deficits (ED3D) of cities/leagues were divided into five categories: Hohhot, Hulunbuir and Banyannur were in larger ecological surplus; Hinggan was in slight surplus; Baotou, Chifeng, Tongliao, Ulanqab, Xilin Gol and Erdos were in slight deficit; Wuhai was in stronger deficit; and Alxa was in severely intense deficit. Woodland of cities/leagues was continuously in slight ecological surplus, while cropland and grassland had crucial impacts on deficit. There was a significant positive linear correlation between gross domestic product (GDP) and footprint, while a negative correlation was seen with deficit. These results would help coordinate resource utilization and industrial structure adjustment in Inner Mongolia.

Ecological footprint theory is used to evaluate the eco-environmental conditions by calculating the area of regional productive land. The research would estimate the environmental sustainability of the lifestyle of residents in Liaocheng city using the ecological footprint as the indicator of consumption. At first, the related conceptions of ecological footprint will be introduced, then analysis the disparity between consumption demand and available supply on the basis on data from statistical yearbook of Shandong Province in 2011. The result shows that the ecological footprint exceeds 27.9 times of ecological carrying capacity which indicate that the city was in unsustainable situation in 2011.

Urban Development Policy

The urban ecological territory model uses traditional ecological evaluation methods, such as ecological carrying capacity and ecological footprint, to create a new urban ecological model that uses a quantified spatial structure. This new model allows for the quantitative analysis of indicators such as ecological efficiency, quality, security, and fairness. The paper presents an example application of the model through a comparative analysis of two cities. Analyses using the new model can be used to guide urban development policy decisions.

This article was based on Beijing treatment of urban Livestock and poultry manure, namely, composting and anaerobic treatment. According with the practical treatment and disposal and combining with the 2006 IPCC internationally cognition and greenhouse gas calculation that related scholars studied, ecological footprint calculation of Beijing urban animal waste was summarized and developed ,thus laid foundation for the study of Beijing urban ecological carrying capacity.

Since the water resourse insome towns of Beijing were in a big shortage in the past few years, it becomes a key factor which restricts the sustainable development and theurbanlization of Beijing. Based on the fact, this paper introduces the reserrch situation and development of the ecological footprint of urban water resourse in Beijing. And it puts forward the method for calculating the the ecological footprint of urban water resourse , includeing domestic water, process water and eological water, in Beijing. Furthermore, the computational method of ecological carrying capacity and ecological deficit of urban water resourse in Beijing is proposed, which provides reference for the evaluation of ecological capacity of urban water resourse in Beijing.

Most of resource-based cities (RBC) are the result of resource-based industrialization processes and were built on mining areas, leading to heterogeneous composition and distribution of urban areas which were lacking of proper urban planning guidance. The unique urbanization processes in RBC resulted in severe fragmentation of habitats and environmental exacerbation and generated negative impacts to human well-being. In this research, an assessment model based on ecological footprint (EF) and ecological carrying capacity (EC) was used to detect the trend of urbanization in Tangshan city. In this model, we created four new indicators which could enrich EF and EC with economic and social dimensions, and categorized six types of ecological footprints into three main kinds of ecological footprints. The results indicated that (a) the EF per capita and the EC per capita have had enormous increment and decrement respectively; (b) ecological tension and ecological occupancy presented a constant increasing trend while the ecological sustainability was continuously decreasing in this period; and (c) almost all of the six indicators were in an unbalanced status in the comprehensive grading system worldwide. We suggest that (a) a diversified energy consumption structure and an energy-saving urban system should be accomplished in the future urban regulation; (b) any shrinkage of fisheries should be avoided in the future urban regulation, and coastal protection and offshore fishing should be prioritized.

Analysis System

On the basis of ecological footprint theory and tourism ecological footprint theory, the sustainable development indexes such as ecological footprint, ecological carrying capacity, ecological deficit, and ecological surplus of the research area were calculated and the long-term change pattern of each index was analyzed. This paper shows that the ecological footprint of the research area increases year by year, but the ecological footprint is always smaller than the ecological carrying capacity, indicating that the area is still in the state of sustainable development. However, the per capita ecological surplus shows a decreasing trend year by year, indicating that the sustainable development of the region is getting worse. This paper proposes a reordering method of tourist attractions based on heterogeneous information fusion, and realizes the retrieval and reordering of tourist attractions based on user query and fusion of heterogeneous information, so as to help users make travel decisions. In view of the shortage of tourism commercial websites to passively provide scenic spot information, this paper puts forward a scenic spot retrieval method based on query words to enable users to obtain scenic spot information according to their needs, and constructs a tourist consumer data analysis system. The preprocessing methods and methods adopted by the data preprocessing module are analyzed in detail, and the algorithms used in the travel route analysis and consumer spending ability analysis are described in detail. The data of tourism consumers are analyzed by this system, and the results are evaluated.
