摘要：

針對(duì)目前利用實(shí)測數(shù)據(jù)對(duì)長江口鄰近海域水質(zhì)狀況進(jìn)行分析研究相對(duì)偏少的情況，基于“淞航”號(hào)2018年春季航次對(duì)該海域的綜合觀測，利用實(shí)驗(yàn)室水樣分析數(shù)據(jù)對(duì)船載溫鹽深儀（CTD）的測量數(shù)據(jù)進(jìn)行校正，并對(duì)該區(qū)域2018年春季時(shí)節(jié)懸浮物（TSM）和葉綠素a （Chl-a）濃度的空間插值結(jié)果進(jìn)行分析。研究結(jié)果表明： CTD觀測數(shù)據(jù)與水樣分析數(shù)據(jù)呈較強(qiáng)線性相關(guān)關(guān)系。反距離權(quán)重插值對(duì)TSM和Chl-a濃度空間分布具有整體最優(yōu)的效果。TSM濃度在近岸和近海底較高，在觀測區(qū)域內(nèi)出現(xiàn)兩個(gè)高值中心； Chl-a濃度在近岸海域較高，有較明顯的片狀高值結(jié)構(gòu)，垂向上表層較高。TSM與Chl-a濃度分布在長江口南北表現(xiàn)出不同的特征，且兩者具有一定的負(fù)相關(guān)性。長江徑流、外海洋流、潮汐混合等水動(dòng)力過程是影響該區(qū)域TSM和Chl-a濃度分布的主要因素。

Considering the relatively few studies utilizing in-situ data on this topic, this study uses the comprehensive observational data collected by the Songhang voyage in spring 2018, to analyze the spatial distribution of total suspended matter (TSM) and chlorophyll a concentrations after correcting shipboard CTD measurements against the laboratory water sample analysis data. The results show that there is a strong linear correlation between CTD measurements and water sample analysis data. The inverse distance weight interpolation has the overall optimal effect on the spatial distribution of TSM concentration and chlorophyll a concentration. The TSM concentration is higher in the nearshore areas and in the bottom water near the seabed, and there are two high-value centers in the observation area; the chlorophyll a concentration is higher in the nearshore areas with obvious flake high-value structure, and higher in the vertical upper surface layer. The distributions of TSM concentration and chlorophyll a concentration in the north and south of the Yangtze River Estuary show different characteristics and negative correlation. The hydrodynamic processes including the runoff of the Yangtze River, ocean currents, and tidal mixing are the main factors affecting the distribution characteristics of TSM concentration and chlorophyll a concentration in the area.
