Early-warning for Environmental and Resource Carrying Capacity on Small Scale——A Case Study of Dapeng Peninsula, Guangdong
It is an important work of promoting ecological progress innovation to establish monitoring and early-warning mechanisms for environmental and resource carrying capacity. The majority of previous studies focused on large-scale areas rather than small-scale areas. In this study, early-warning index systems for environmental and resource carrying capacity have been built both at district and sub-district level for Dapeng Peninsula of Shenzhen. The division of environmental and resource carrying capacity from whole to part was discussed. The early-warning status of environmental and resource carrying capacity was assessed in 2014. The results showed that the environmental and resource carrying capacity of Dapeng Peninsula in 2014 was at light-alert level. Land resource, water resource, ecological resource, marine environment and atmospheric environment carrying status were at no-alert or light-alert level, while surface water environment and infrastructure carrying capacity were weak spots, with water environmental carrying status at serious warning level. There were no obvious regional differences at comprehensive early-warning status of environmental and resource carrying capacity among three sub-districts, while there were obvious regional differences at early-warning status of single factor carrying capacity among three sub-districts. Land resource and water environmental carrying status of Kuichong sub-district were best among three sub-districts, while water resource carrying status of Nanao sub-district was best among three sub-districts. Land resource, water environmental and infrastructure carrying status of Dapeng sub-district were worst among three sub-districts. This study will be beneficial for the decision-making of environment and resource utilization and regional sustainable development and provide a reference for the establishing of early-warning system of environmental and resource carrying capacity for other regions at small scale.
