摘　　要：本研究旨在通过Landsat-8和哨兵二号卫星影像数据,深入探究深圳湾红树林的分布变化。通过面向对象分类方法精确分类2013年、2018年和2023年的卫星影像数据,分析发现深圳湾红树林面积在十年间持续增长,从358.83公顷增至441.41公顷,年增长率达1.8%,且福田区红树林保护中心区域增长尤为明显。这一研究不仅为深圳湾红树林保护提供了科学依据,也为红树林生态系统的保护和管理提供了实践指导。This study aimed to conduct an in-depth investigation of the distribution changes of mangrove in Shenzhen Bay using Landsat-8 satellite imagery and Sentinel-2 satellite imagery data. By employing an object-oriented classification method to accurately classify the features in the images from 2013, 2018, and 2023, the analysis reveals that the mangrove area in Shenzhen Bay has continued to expand over the past decade, growing from 358.83 hectares to 441.41 hectares, with an annual growth rate of 1.8%. Notably, the growth is particularly evident in the mangrove conservation center area of Futian District. This research not only provides a scientific basis for the conservation of mangrove forests in Shenzhen Bay but also offers practical guidance for the protection and management of mangrove ecosystems.
