摘要

近岸水质的科学评估和预测对海洋环境保护工作至关重要。本研究在综合分析现有评估和预测方法的基础上，考虑了自然和人为影响导致的近岸海水水质的规律性和随机性特征。它提出了一种新方法，将克里金插值算法应用于根据经验生成的时空半变量图，以评估和预测海水水质。该方法在福建沿海地区的应用表明，它能够灵活、科学地估算该地区各项指标的变化情况。结合 GIS 空间数据叠加分析操作，可用于定量评价海水的不同质量，为海洋环境保护提供科学指导。

Assessing and Predicting Nearshore Seawater Quality with Spatio-Temporal Semivariograms: The Case of Coastal Waters in Fujian Province, China

The scientific assessment and prediction of nearshore water quality are crucial for marine environment protection efforts. This study is based on a comprehensive analysis of existing assessment and prediction methods and considers the regular and random characteristics of nearshore seawater quality due to both natural and anthropogenic influences. It proposes a new method that applies the kriging interpolation algorithm to empirically generated spatio-temporal semivariograms to assess and predict seawater quality. The application of this method in Fujian coastal areas shows that it is able to flexibly and scientifically estimate the variations in various indicators in the region. Combined with GIS spatial data overlay analysis operations, it can be used to quantitatively evaluate different qualities of seawater and provide scientific guidance for marine environmental protection.
