【摘要】：从现有环境压力、开发利用水平及发展潜力三个方面提出了区域环境承载力开发利用潜势这一新的概念,并从区域环境承载率、区域资源利用与污染物排放强度、区域发展能力三个角度选取了29个指标构建了环境承载力开发利用潜势评价指标体系。以北海市为例,对其环境承载力开发利用潜势进行评价。结果显示,北海市的现状发展模式尚属于可持续发展模式。但其环境承载压力仍然较大,还需提高区域发展能力。对北海市三区一县来说,海城区环境承载力开发利用潜势最高;合浦县排在第二位,其区域承载压力相对较小,开发利用水平较高,但区域发展能力较低。铁山港区环境承载力开发利用潜势最低,虽其区域发展能力最高,但仍需提高其开发利用水平、降低资源环境承载压力。结果表明,环境承载力开发利用潜势评价体系的建立是可行的,它可以描述某一城市时域上的变化,也可以从空间上评估某一区域各单元的不同,甄别区域环境承载力开发利用过程中存在的问题,可以为我国资源环境承载力监测预警机制的建立提供参考。
[Abstract]:From the three aspects of existing environmental pressure, development and utilization level and development potential, the new concept of regional environmental carrying capacity development and utilization is put forward, and the potential development and utilization potential of environmental carrying capacity is constructed from the three angles of regional environmental carrying rate, regional resource utilization and pollutant discharge intensity and regional development ability. The evaluation index system, taking Beihai as an example, evaluates the potential development and utilization of its environmental carrying capacity. The results show that the current development model of Beihai is still a sustainable development model. However, its environmental carrying pressure is still larger and the regional development capacity needs to be improved. For the three district and one county of Beihai, the development and utilization of environmental carrying capacity in Haicheng District The potential of Hepu county is the highest in second place, its regional bearing pressure is relatively small, the development and utilization level is high, but the regional development ability is low. The development and utilization of environmental carrying capacity of Tieshan port area is the lowest, although its regional development ability is the highest, but it still needs to improve its development and utilization and reduce the carrying pressure of resources and environment. It is feasible to establish the potential evaluation system for carrying capacity development and utilization. It can describe the changes in the time domain of a certain city. It can also assess the different units in a certain area from the space, and identify the problems in the development and utilization of the regional environmental carrying capacity. It can provide a reference for the establishment of the monitoring and early warning mechanism for the carrying capacity of resources and environment in China. Exam.
