Assessment of Ecological Carrying Capacity on the Typical Resources-based Cities-a Case Study of Tangshan City

Abstract

The power of human activities in resource鄄based cities overload its ecological carrying capacity, such as mining, land occupying, and ore smelting supported by resources and environment. The relative research on the development of the cities is a hot topic over the world, the sustainable development of resource鄄based cities has become one of most prominent issues in China. The ecological carrying capacity reflects the harmony of human and ecosystem, including their interactive and symbiotic relationship, which should be used as an important criterion of region sustainable development. In past, the studies on ecological carrying capacity were largely confined to basin and region scales until the urban complex ecosystem theory was put forward. Thereby it is very inevitable to study the urban ecological carrying capacity and eco鄄regulation for its sustainable development. Tangshan, nearly hundred years of mining history, may be one of the fastest developing resource鄄 based cities in China, as well as one of most prominent representative of the cities which has poignant contradiction of the location: population boom, resources depression and environment deterioration. Based on the regional unique characteristics

Ecosystem Health Evaluation and Ecological Security Patterns Construction Based on VORSD and Circuit Theory: A Case Study in the Three Gorges Reservoir Region in Chongqing, China

“…(7) The nature reserves data came from the China Nature Reserve Specimen Resources Sharing Platform (https://www.papc.cn/, accessed on 6 October 2021). (8) The statistical data on water consumption, grain consumption, and carbon emission came from the Water Resources Bulletin, the Chongqing Statistical Yearbook, and the China Emissions Inventories and Datasets (CEADs), respectively.…”

“…This intensification has caused a series of ecological problems, such as a decrease in soil erosion control, biodiversity and carbon storage, resulting in environmental degradation that affects regional sustainable development and ecological security [2][3][4]. As people pay more and more attention to the ecological environment and the sustainable development of human society, ecological security, the basis for ecosystems to provide various ESs for humans and guarantee ecosystem health, has been well developed in terms of its related theories and research methods [5][6][7], including ecological carrying capacity [8], ecological restoration [9], ecological security patterns [5,7] and nature reserve planning [10]. As an effective way to represent the health and integrity of ecosystems and alleviate the contradiction between ecological protection and sustainable socio-economic development, ecological security patterns (ESPs) have received extensive attention [11].…”

Variation in the Ecological Carrying Capacity and Its Driving Factors of the Five Lake Basins in Central Yunnan Plateau, China

“…This is because ecological carrying capacity is an important indicator of sustainable development. Methods used in research into regional ecological carrying capacity have included net primary productivity (NPP) [16][17][18], the ecological footprint method [19][20][21][22], the state space method [23][24][25], and the comprehensive index method [26][27][28][29][30]. Among these methods, the comprehensive index method is the most comprehensive, is of certain relevance for the selection of factors, and is suitable for areas with more complex ecological and environmental conditions.…”

Identification of Priority Areas for Improving Urban Ecological Carrying Capacity: Based on Supply–Demand Matching of Ecosystem Services

“…It is arguably the most widely accepted definition. From then on, many studies have followed this definition or adjusted and supplemented it on this basis, such as Jin et al [19], focusing on the urban ecosystem, who recognized that ECC is an important criterion for measuring the sustainable development capacity of a certain area. He divided the urban ecosystem into four sub-systems of resources, environment, society, and economy, and considered that ECC includes three levels: the self-sustaining and self-regulating ability of the ecosystem, the supply capacity of the environmental and resource subsystems in the ecosystem, and the pressure on the environment and resource subsystems caused by human activities and social economic production activities; Yang and Sui [20] proposed the concept of ECC based on ecosystem health, which refers to the potential capacity of natural ecosystems to maintain their service functions and their own health under certain social and economic conditions.…”
