Research on the Measurement of Sea Area Use and Technology Development Trends Based on Blue Ocean

Abstract

The ocean is the cradle of life and a regulator of the environment. The development and utilization of marine areas constitute a vital aspect of national socio-economic development. Marine spatial use surveying serves as a critical technical link connecting "marine resources - ecological environment - human activities", with its significance permeating the entire chain of marine resource management, ecological protection, rights safeguarding, engineering construction, and scientific decision-making. Accurate marine spatial use surveying has become a fundamental cornerstone for promoting high-quality marine development and achieving the sustainable utilization of the "blue territory". From the perspective of protecting the ocean and developing and utilizing it scientifically, this paper elaborates on the significance of marine spatial use surveying by comparing and analyzing the implementation status, applied technologies, management mechanisms, challenges, and China's development status in this field internationally and domestically. Finally, the paper summarizes and discusses the development trends of marine spatial use surveying.
