中文摘要：

本文从信息分析理论出发,研究了悬浮泥沙的时空结构与时空分析模式。由于悬浮泥沙在时间变化上既具有周期性又具有随机性,在空间上存在区域差异,所以从信息分析理论角度,悬浮泥沙时间分析模式可分为基于时间跨度的时间分析模式和基于变动因素的时间分析模式,而悬浮泥沙空间分析模式可分为空间变化分析模式和空间类比分析模式。基于以上时空分析模式,本文选择珠江口及其邻近海域1995年～2000年152个时相的NOAA/AVHRR影像反演的悬浮泥沙浓度结果,及泥沙输移模型模拟的悬浮泥沙浓度,对珠江河口及深圳湾悬浮泥沙进行周期性变化分析、趋势面分析和垂向变化分析。研究表明,珠江河口悬浮泥沙具有明显的月变化、季节变化、丰枯水期变化及涨落潮变化规律,而深圳湾悬浮泥沙在垂向上则表现出由底层向上逐渐降低的变化规律。

英文摘要：

According to the information analysis theory, the temporal-spatial structure and analysis pattern of suspended sediment concentration are studied. Due to the randomness and periodicity of the temporal structure and the regional differences of the spatial structure in suspended sediment concentration, the temporal analysis pattern of suspended sediment concentration is divided into time-span analysis pattern and time-varying analysis pattern. The time-span analysis pattern is further divided into backward analysis, present analyzes and forecast analysis, while time-varying analysis pattern is sub-divided into long-term trend change analysis, periodic change analysis and irregular change analysis. The spatial analysis pattern of suspended sediment concentration is divided into space change analysis pattern and spatial analogy analysis pattern. Spatial change analysis is further divided into distance attenuation analysis, trend surface analysis, zoning analysis and vertical changes analysis, while spatial analogy analysis pattern is divided into different time analog analyses in the same area, different time analog analyses in different regions and different regional analog analyses at the same time etc. In this paper, the temporal-spatial law of suspended sediment concentration in the Pearl River estuary and Shenzhen Bay based on the above temporal-spatial analysis pattern are studied. The study results indicate the periodic change of the suspended sediment concentration in the Pearl River estuary. To specify, the suspended sediment concentration is higher in summer than in spring and autumn, and it can be the lowest in winter. In addition, the concentration contour is roughly parallel to the coastline and the values decrease from river mouth to the open sea. On the side, the suspended sediment concentration in the Shenzhen Bay also shows an obvious spatial distribution as well as a tidal cycle in its temporal variation. The suspended sediment concentration usually decreases from northwest to southeast. In view of
