The Control Line Delineation Method of Coastal Resources Development and Utilization: Take Taizhou as an example

Abstract

In order to promote the sustainable development and utilization of coastal resources in China, this paper discussed the delimitation method of the control line for the development and utilization of coastal resources by establishing an index system and a calculation model, and applied it in Taizhou on the basis of data analysis. The results showed that the delimitation of the control line for the development and utilization of coastal resources must comprehensively consider the intensity of resource development and utilization, the response of environmental factors, the response of ecological factors, the degree of ecological environment protection and regional economic development, and calculated the environmental pollution index and the expected pollution reduction target. The environmental pollution index of Taizhou City in 2018 was 0.059, and the expected targets for the moving distance to sea of sensitive areas (areas with excellent water quality) and chlorophyll a concentration in 2025 would be 1 000 m and 7 500 m respectively, and the expected pollution reduction target would be 1.493. According to the ecological environment protection level and economic development status of each coastal county-level administrative region, the delimitation distance of Taizhou coastal resources development and utilization control line in 2025 would be 0~7 872 m. The delimitation results not only reflected the overall allocation of regional resources, but also ensured regional differentiated development and met the needs of regional coordinated development.
