摘　　要：高分卫星遥感影像能够有效提高生态监测频率和效率,在掌握生态区内基本环境变化的同时,识别可能存在的生态环境破坏、突发灾害等情况,保证整体生态区内人类活动与自然资源的动态平衡,具有良好的社会效益。本文基于高分卫星影像,利用归一化植被指数(NDVI)进行植被提取,再结合实地考察,提取各类用地影像特征,完成了三亚市育才生态区主要用地类型分类,并开展生态资源监测和农业资源调查。通过2年4期遥感监测,重点监测了生态区用地类型变化、水库面积变化对库区周边用地的影响以及工程建设对生态区环境的破坏情况,获得了育才生态区生态资源监测的相关成果。High-definition satellite remote sensing imagery can effectively improve the frequency and efficiency of ecological monitoring, identify possible ecological damage and sudden disasters while grasping the basic environmental changes in the ecological zone, and ensure the dynamic balance between human activities and natural resources in the overall ecological zone with good social benefits.Based on the high resolution satellite images, the NDVI index was used for extract vegetation extraction.Then the image characteristics of various types of land use were extracted with the help of field investigation to complete the classification of main land use types and carry out ecological resource monitoring and agricultural resource survey in Yucai Ecological Zone of Sanya.Through the four periods of remote sensing monitoring in two years, the change of land use type in the ecological zone, the impact of the change of reservoir area on the land around it and the damage of engineering construction to the environment in the ecological zone were closely monitored.The relevant results of ecological resource monitoring in Yucai Ecological Zone were obtained.
