利用相干模式识别方法分析了海水入侵影响下海岸带土地利用与土地覆盖对蒸散量的影响。利用陆地卫星数据对莱州湾的土地利用变化进行了研究。然后，利用两时相热红外波段图像和区域地表参数，采用陆地模型表面能量平衡算法估算了ET和热通量。这使得海水入侵的最终链接到土地利用/覆盖变化（LUCC）和ET随时间的变化。本研究利用多源、多传感器遥感技术对海岸带景观动态进行了评价。结果如下：（1）由于远离海洋，修正的土壤调节植被指数（MSAVI）随着土地利用等级（Uindex）的逐渐增大而逐渐增大;（2）参数之间存在多种类型的关系模式（LST、Gn、MSAVI和Uindex）和ET（3）海水入侵显著影响LUCC的空间格局，进而影响ET的空间分布。在区域气候背景作用下，海水入侵和LUCC的双重驱动力形成了ET的空间分布格局和变化特征。
The paper provides a coherent pattern identification analysis of the impacts of coastal land use and land cover (LULC) on evapotranspiration (ET) under the impact of seawater intrusion. The study applied the Landsat satellite data to characterize the LULC at Laizhou Bay, Shandong Province, China. Then, the ET and heat fluxes were estimated using the surface energy balance algorithm for land model with two-time phase thermal infrared band images and regional surface parameters. This allowed for the eventual linkage of seawater intrusion to land use/cover changes (LUCC) and ET variations over time. The case study discussed in this paper carried out a coastal landscape dynamics assessment using multi-source and multi-sensor remote sensing technologies. The results are: (1) due to its distance from the sea, the vegetation index (modified soil-adjusted vegetation index, MSAVI) gradually increases with the gradual increase of land use grade (Uindex); (2) there are a variety of types of relational patterns between parameters (LST, Gn, MSAVI, and Uindex) and ET (positive, negative, and no relationship); and (3) seawater intrusion significantly affected the spatial pattern of LUCC, which evidently affected the spatial distribution of ET. The spatial distribution pattern and change characteristics of ET were formed by double driving forces of seawater intrusion and LUCC under the background effects of regional climate.
