【摘要】：建立资源环境承载力监测预警机制,是生态文明制度创新的一项重要工作。已开展的资源环境承载力研究多针对大尺度区域,而针对小尺度区域开展的研究相对较少。该研究在小尺度水平,以大鹏半岛为例,分别从区级和街道级两个层次构建了资源环境承载力预警评价指标体系,定量评价了2014年大鹏半岛资源环境承载状况,对资源环境承载力整体-局部的分配问题进行了探讨。结果表明,大鹏半岛资源环境承载力总体上处于轻警状态,3个街道的综合资源环境承载状况较为一致。土地资源承载力、水资源承载力、生态资源承载力、海洋环境承载力、大气环境承载水平均较高,表现为无警或轻警水平;但地表水环境承载力和固废、交通等基础设施承载力是其短板,特别是地表水环境承载力,大鹏半岛的承载指数为0.36,处于重警水平。3个街道在单要素承载力方面存在空间差异。其中,葵涌街道的土地资源和水环境承载状况最好,大鹏街道的土地资源、水环境、基础设施承载状况最差,南澳街道的水资源承载状况最佳。研究成果可为该区域资源环境开发利用、可持续发展决策提供更精准的技术支撑,也可为其他地区的小尺度资源环境承载力监测预警体系研究提供参考借鉴。
[Abstract]:It is an important work to establish the monitoring and warning mechanism of the carrying capacity of resources and environment, which is an important work of the system innovation of ecological civilization. Most of the researches on carrying capacity of resources and environment have been carried out on large scale areas. The research on small scale area is relatively few. Taking Dapeng Peninsula as an example, the paper constructs an early warning evaluation index system of the carrying capacity of resources and environment from two levels: district level and street level. In 2014, the paper quantitatively evaluated the carrying capacity of resources and environment in Dapeng Peninsula, and discussed the overall and local distribution of the carrying capacity of resources and environment. The carrying capacity of resources and environment in Dapeng Peninsula is in the state of light warning, and the comprehensive carrying capacity of resources and environment in three streets is the same. The carrying capacity of land resources, water resources and ecological resources is the same. The bearing capacity of marine environment and atmospheric environment are all high, showing the level of no warning or light warning. However, the surface water environmental carrying capacity, solid waste, traffic and other infrastructure carrying capacity is its short plate, especially the surface water environmental carrying capacity. The bearing capacity index of Dapeng Peninsula is 0.36. In the level of heavy warning. The three streets in the single element of the bearing capacity of space differences. Among them, the Kwai Chung street land resources and water environment bearing the best condition, Dapeng street land resources, water environment. The research results can provide more precise technical support for the development and utilization of resources and environment in the region and for the decision of sustainable development. It can also provide reference for the study of monitoring and early warning system of small scale resources and environment carrying capacity in other regions.
