Devido ao crescimento populacional ao longo dos séculos e, consequentemente, a expansão das cidades, cada vez mais é notável a influência de ações antrópicas, causadoras de distúrbio nos ecossistemas naturais e urbanos. O presente estudo visa introduzir os conceitos de sustentabilidade, capacidade de carga e resiliência ambiental, através do tracejamento de um panorama histórico do desenvolvimento sustentável e a sua importância para o surgimento de uma nova racionalidade ambiental, importante e necessária para que haja a manutenção do equilíbrio destes ecossistemas, não sendo rompido o ponto de equilíbrio da resiliência ambiental devido a uma sobrecarga do número de usuários em um determinado espaço. Os resultados apontam a necessidade da construção de uma racionalidade ambiental para que se possa minimizar os impactos causados ao meio ambiente, através de uma mudança comportamental mais profunda.    A B S T R A C T Due to population growth over the centuries and hence the expansion of cities, is remarkable the increasingly influence of antrophic activities, causing disorder in the natural and urban ecosystems. This study aims to introduce the concepts of sustainability, carrying capacity and environmental resilience, through the trail of a historical overview of sustainable development and its importance for the emergence of a new environmental rationality, important and necessary to maintain the balance of these ecosystems, not being broken the balance of environmental resilience due to an overload of the number of users in a given space. The results show the need for the construction of an environmental rationality so that we can minimize the impacts to the environment, through a deeper behavioral change.

Grassland resources are an important part of land resources. Moreover, it has the functions of regulating the climate, windproof and sand fixation, conserving water sources, maintaining water and soil, raising livestock, providing food, purifying the air, and beautifying the environment in terrestrial ecosystems. Grassland resource evaluation is of great significance to the sustainable development of grassland resources. Therefore, this paper improves the BP neural network, uses the comprehensive index method to calculate the weights in the analytic hierarchy process, and constructs a water resources carrying capacity research and analysis system based on the entropy weight extension decision theory. Meanwhile, this paper analyzes different levels of resource and environmental carrying capacity to achieve the purpose of comprehensive evaluation of resource and environmental carrying capacity. In addition, based on the theory of sustainable development, under the guidance of the principle of index system construction, this paper studies the actual situation of grassland resources and the availability and operability of data, and combines with the opinions given by experts to form an evaluation index system of grassland resources and environmental carrying capacity. Finally, through the actual case study analysis, it is concluded that the model constructed in this paper has a certain effect.

Land carrying capacity is an important indicator to quantitatively assess and judge the extents of sustainable economic developing and coexistent harmonizing between human and nature. The significance of land carrying capacity has been highlighted recently by the Sustainable Development Goals (SDGs) of the United Nations, which set clear requirements for arable, construction, and ecological lands. Theories and models of land carrying capacity, however, are suffering from the interference of artificial parameter setting and poor applicability. This paper attempts to overcome these limitations and propose a single factor assessment of the carrying capacity of cultivated land, construction land, and ecological land in terms of the relative carrying capacity from the perspective of a single factor assessment. Through mutual comparison, we found that the deviation caused by simulated parameter setting has been eliminated, and the relative status of each province and/or region in China has been obtained, which could provide a reference for the management and utilization of land resources. We argue that China can achieve basic self-sufficiency in both space capacity and food production without placing pressure on the global sustainable development. The results also indicate that carrying capacity state of the advanced development areas such as the eastern coastal region is relatively poor, while the carrying capacity state of the western region is relatively good.

ABSTRACTThe search for sustainability indicators should be guided by a theory of sustainable development (SD). In this paper we investigate two such theoretical frameworks and the indicators that they suggest. Indicators associated with weak sustainability are characterized by aggregative indicators such as green national income. We conclude, however, that a more promising offshoot of green accounting is measures of genuine savings (i.e. savings adjusted for loss of assets). To achieve SD, genuine savings rates must not be persistently negative. Strong sustainability indicators accord a more central role to the conservation of critical natural assets within the broader goal of prudently managing a nation's portfolio of assets over time. We discuss two approaches—carrying capacity and resilience—and conclude that, while measures of resilience are potentially attractive, more research is required regarding the resilience–SD link. However, an important conclusion that we can make is that, even in an economy operating under a strong sustainability regime, genuine savings are still key indicators of SD and are complementary to measures of changes in stocks of critical natural assets.

Rapid social-economic development and the ever-increasing water pollutant discharge of Wuliangsuhai lake basin made the water quality deteriorated; the lake eutrophication intensified and heavily restricted the sustainable development of the watershed’s social economy. Wuliangsuhai lake basin was selected as the study area. By the use of system dynamics simulation model the water environment and social economy were connected, and three kinds of improved scenarios (resource-environment constrained type, social economy constrained type, coordinated development type) were proposed based on the inertial and planning schemes. Ten indexes of water environment carrying capacity, i.e. the GDP per capita, ratio of industrial output to GDP, et al., were selected, and fuzzy comprehensive evaluation method was used. Results showed that, the water environmental capacity utilization ratios of COD and TN in the resource-environment constrained scenario were 69.5% and 57.9% in 2020, respectively. And the water environment carrying capacity index increased from 0.19 in 2008 to 0.31 in 2020. Under the coordinated development scenario, the surplus environmental capacity of COD and TN were 1755.46t/a, 260.21t/a respectively, and the water environment carrying capacity index was up to 0.29 in 2020. The sustainable development plan was proposed and some feasible suggestions and strategies were put forward.

With the rapid urbanization in recent decades, resource shortage and environmental damage have hindered the process of urban sustainable development (SD). As a yardstick of sustainable development, the evaluation of resources and environment carrying capacity (RECC) and its decoupling relationship with social comprehensive development index (SCDI) are of great significance. In this paper, RECC and SCDI are taken as research objects to establish resource and environment system evaluation index system and social comprehensive development level evaluation index system, respectively. Then, the RECC and SCDI of 17 cities in Hubei province during 2009–2018 are calculated by the projection pursuit model based on genetic algorithm, and their spatial-temporal variance characteristics are analyzed. On this basis, the RECC-SCDI Tapio decoupling model is constructed to explore the decoupling relationship between RECC and SCDI. The result shows that: (1) The RECC of Hubei shows a V-shaped development trend during 2009–2018. The SCDI of Hubei rose steadily during 2009–2018. (2) RECC in western and eastern Hubei Province is higher than that in central Hubei Province. SCDI in eastern and central Hubei Province is higher than that in the west. (3) 11 of the 17 cities in Hubei Province have got rid of excessive dependence on resources environment for social development. The study could contribute to scientific and effective policies be formulated by government to promote urban sustainable development.
