Port Said Governorate is one of the distinguished Egyptian coastal areas in regard to location, activities and resources. Present study aims to evaluate spatial and temporal changes in Land Use/Cover (LULC), Land Surface Temperature (LST) and Shoreline as a result of natural and anthropogenic factors using geospatial techniques. To achieve this aim, four calibrated multi-temporal Landsat images dated 1998, 2008, 2018 and 2021 integrated with field surveys were processed. Nine main LULC classes were mapped; urban, fish farms, vegetation, aquatic plants, main roads, bare land, water, canals/drains and salty areas. Developmental projects, particularly reclamation and urbanization, accelerated the increase in urban and agricultural lands during the whole period of study. Maximum rate of urban expansion was reported during the last period (2018–2021) and for agricultural lands during 2008–2018. The south eastern parts showed a continuous annual increase in the fish farms from 2.04 to 6.54 to 65.16 km² at 1998, 2008, 2018 and 2021, respectively. Further, the last periods showed an increase in the main roads due to the construction of “30 June Road”. A small variation is observed in mean LST recording 34.2, 33.7 and 34.3, 34.2° C at 1998, 2008, 2018 and 2021, respectively. LULC can be ordered from lowest to highest LST as following; water (27.1 °C), aquatic plants (28.1 °C), fish farms (30.6 °C), vegetation (31.9 °C), canals and drains (33.8 °C), urban (36.45 °C), salty areas (36.6 °C), main roads (37.20 °C) and bare land (39.40 °C). The total eroded area along Port Said shoreline (5 km²) exceeds the total accreted areas (2.8 km²). Maximum erosion and accretion were observed at the eastern sector recording 2.61 and 1.29 km², respectively. Fortunately, no intensive urban and agricultural areas are located in this sector which minimizes the probable adverse impact.

塞得港省在地理位置、活动和资源方面是埃及著名的沿海地区之一。本研究旨在利用地理空间技术评估自然和人为因素导致的土地利用/覆盖 (LULC)、地表温度 (LST) 和海岸线的时空变化。为了实现这一目标，我们处理了 1998 年、2008 年、2018 年和 2021 年与实地调查相结合的四张校准的多时相 Landsat 图像。绘制了九个主要的 LULC 类；城市、养鱼场、植被、水生植物、主要道路、裸地、水域、运河/排水沟和盐渍区。在整个研究期间，开发项目，特别是填海造地和城市化，加速了城市和农业用地的增加。在上一时期（2018-2021 年）和农业用地在 2008-2018 年期间报告了最大城市扩张率。东南部的养鱼场从 2.04 公里增加到 6.54 公里，再到 65.16 公里，每年都在增加。^{2 分别}在 1998 年、2008 年、2018 年和 2021 年。此外，由于“6 月 30 日路”的建设，前期主要道路有所增加。在 1998 年、2008 年、2018 年和 2021 年，平均 LST 记录分别为 34.2、33.7 和 34.3、34.2°C，观察到一个小的变化。LULC 可以从最低到最高 LST 排序如下；水 (27.1 °C)、水生植物 (28.1 °C)、养鱼场 (30.6 °C)、植被 (31.9 °C)、运河和排水沟 (33.8 °C)、城市 (36.45 °C)、盐渍区 (36.6 °C)、主要道路 (37.20 °C) 和裸地 (39.40 °C)。塞得港海岸线沿线的总侵蚀面积（5 km ²）超过了总积土面积（2.8 km ²）。在东部地区观察到最大的侵蚀和吸积，记录为 2.61 和 1.29 公里²， 分别。幸运的是，该部门没有密集的城市和农业区，这将可能的不利影响降至最低。
