摘　　要：珊瑚礁生态系统具有很高的生物多样性和重要的生态功能。20世纪80年代以后全球范围内珊瑚礁的大面积退化引起了人们广泛的关注。利用高分辨多光谱QuickBird影像,基于珊瑚礁几何参数与发育指数对南沙典型岛礁发育进行遥感监测,在珊瑚礁体迎风面水域由破波形成的纹理特征表明了海面粗糙度与水下礁坪的发育特性。结果表明,南沙岛礁受地质与气候的影响发育程度不一,半月礁发育较好,发育指数为0.38,仙娥礁发育指数为0.27。建立几何参数等指标能够监测南沙珊瑚礁的发育状况,可对珊瑚礁的保护提供科学依据。Coral reefs are the high ecological system of biodiversity and have an important ecological function.After the 1980s large degradation of global scope of coral reefs caused people wide attention.Using high resolution images based on Quickbird data,coral reefs geometry parameters and development index the Nansha typical reef development is monitored through remote sensing In the waters against the wind,coral reefs bodies there are the texture characteristics,which shows that the sea surface roughness and underwater reef development characteristics.The results show that because Nansha reefs are inflnencdby geologiy and climate,development degree is differ,half moon reef development is better,development index is 0.38,the reef development index of 0.27.Geometry parameters to are estabtished monitor the Nansha coral reef development status which can provide the scientific basis the protection of the coral reefs.
