三亚城市景观变化的监测研究

区域生态环境变化的动态监测是自然资源合理利用和区域环境保护中急需解决的问题。本项研究采用了遥感技术，对三亚城市景观中不同景观组分的优势度值和边界形状等空间结构指标，对林木覆盖率和生物量等景观稳定状况指标进行了监测，同时配合了典型采样和勘测等地面工作，提高监测数据的可信度。在此基础上建立了区域生态环境变化监测体系和Sanya－Landscape信息系统，对三亚城市生态环境变化趋势进行了评价，准确地反映了该区域生态环境的现状和特征，为三亚城市生态环境的规划和管理提供了科学依据。结果证明，本研究采用的指标及指标的采集方法是区域生态环境动态监测的有效手段。

Monitoring on landscape changes in Sanya

Monitoring on regional eco environmental changes is one of the urgent task in natural resource development and environmental protection.In the study,the dominance and boundary shape of different landscape elements are chosen as indicators to monitor the landscape structure;and woodland coverage,biomass and biodiversity are chosen as indicators to monitor the landscape stability,with data related to these indicators collected by means of remote sensing and checked through field monitoring.On the monitoring basis,a scientific indicator system for monitoring the regional eco environmental changes and a friendly information system Sanya Landscape have been established;and the change trends of eco environment in Sanya are predicated and evaluated,which can provide scientific basis for eco environment planning and management for Sanya city.The results show that the indicators chosen and the methodology used in the study are effective means for eco environment monitoring.
