粤港澳大湾区地表水及海水水质评价图

依据《中华人民共和国海水水质标准-GB3097-1997》和《中华人民共和国地表水环境质量标准-GB3838-2002》，利用综合指数法对大湾区近岸海水及陆域地表水监测站位的水体质量进行评价。在站位水质评价基础上，利用泛克里格插值法获取整个大湾区水体质量平面分布数据。

Pursuant to the Seawater Quality Standard of the People's Republic of China (GB3097-1997) and the Environmental Quality Standards for Surface Water of the People's Republic of China (GB3838-2002), the comprehensive index method was adopted to evaluate the water quality of monitoring stations for coastal seawater and terrestrial surface water within the Guangdong-Hong Kong-Macao Greater Bay Area. Based on the water quality assessment results of these monitoring stations, the universal Kriging interpolation method was employed to obtain the planar spatial distribution data of water quality across the entire Greater Bay Area.
