陆海统筹背景下唐山市资源环境承载力综合评价

十八大以来,海洋产业在沿海地区发展中的作用日益显现,唐山市是一个非典型的沿海城市,海洋开发空间大,在陆海统筹背景下评价资源环境承载力对唐山市陆海统筹发展意义重大。本文以陆海统筹为背景,从资源、环境、社会经济三个角度构建唐山市资源环境承载力指标体系,利用层次分析法确定指标权重,定性、定量地评价唐山市及其沿海区县资源环境承载力。结果表明:2005～2016年唐山市资源环境承载力得分呈上升趋势,2016年得分75分约是2005年的2.6倍,得分年均增速达9.1%;5个沿海区县中,滦南县的承载力状况较优。根据评价结果,提出优化产业结构及提升海洋经济活力、打造沿海城市形象等建议,提升陆海统筹背景下唐山市资源环境承载力。

Comprehensive evaluation on carrying capacity of resources and environment under the background of land-sea coordination in Tangshan City

Since the 18th National Congress of the Communist Party of China, the role of marine industry in the development of coastal areas has become increasingly prominent. Tangshan City is an atypical coastal prefecture-level city, and there is great space for the future development of marine industry, overall promotion of land and marine development is the main task of coastal areas, therefore, the comprehensive evaluation on carrying capacity of resources and environment under the background of land-sea coordination is of great significance to the land-sea coordinated development for Tangshan City. An index system of the carrying capacity of resources and environment in Tangshan City under the background of land-sea coordination from three aspects of resources, environment and social economy is constructed in this study. The weight of indicators is determined by analytic hierarchy process, and the carrying capacity of resources and environment under land-sea coordination in Tangshan City and its five coastal districts and counties is evaluated qualitatively and quantitatively. The results show that the scoring of resources and environmental carrying capacity under land-sea coordination in Tangshan City is generally on the rise from 2005 to 2016. The scoring of 75 points in 2016 is about 2.6 times that of 29 points in 2005, with an average annual growth rate of 9.1%. Among the five coastal districts and counties, Luannan County has a better carrying capacity. According to the evaluation results, some suggestions are put forward, such as optimizing the industrial structure and enhancing the vitality of marine economy, creating the image of coastal cities, and adhering to land. So as to enhance the carrying capacity of resources and environment in Tangshan City under the background of land-sea coordination.
