Remote-Sensing Analyses of Asian Coastal Environments

(1)沿海高污染地区卫星遥感影像数据分析方法的推广与应用：为适应亚洲沿海地区自然环境和环境条件与日本不同的情况，尝试推广宫崎和南冈的方法，用于沿海环境监测的卫星遥感影像数据分析。该方法基于光学理论和非线性优化技术。通过与青岛东京湾和胶州湾海域的海真数据对比，证明了该方法的基本有效性和良好的性能。本文还对该方法在菲律宾马尼拉湾等高污染沿海地区的适用性进行了进一步讨论。(2)珊瑚礁的卫星遥感和与相关监测技术的结合：为了对珊瑚礁进行环境监测，在冲绳群岛进行了实地测量，并进行了相关的卫星遥感分析。珊瑚礁的存在是亚洲沿海地区的特征。此外，我们沿冲绳岛部署了一个由小型记忆式温度计组成的水温监测网。在菲律宾，与菲律宾大学海洋科学研究所的一个小组合作，也进行了部署一些温度计的类似尝试。对卫星遥感数据和温度计数据的分析已成功地用于调查珊瑚白化现象，这种现象在1998年发生在世界各地，包括冲绳群岛和菲律宾。(3)建立珊瑚礁-红树林生态系统国际联合研究项目的尝试：通过本研究，尝试建立一个国际联合研究项目，由上述MSI/UP、James Cook大学、昆士兰大学等课题组参与，开发更综合的珊瑚-红树林生态系统监测系统。少

(1) Generalization and application of the method to analyze satellite remote sensing image data for highly contaminated coastal zone :For adapting to the situation in Asian coastal environments, in which natural and environmental conditions may differ from those in Japan, it has been attempted to generalize the method developed by Miyazaki and Nadaoka to analyze satellite remote sensing image data for monitoring coastal environments. This method is based on an optical theory and a nonlinear optimization technique. Comparison with the sea-truth data obtained both in Tokyo Bay and Jiaozhou Bay in Tsingtao has shown the fundamental validity and high performance of the present method. Further discussion has been also made for the applicability of the method to highly polluted coastal area in the Philippines such as Manila Bay.(2) Satellite remote sensing of coral reefs and integration with associated monitoring techniques :For environmental monitoring of coral reefs, the existence of which … More characterizes Asian coastal areas, field measurements in Okinawa islands have been made with associated satellite remote sensing analyses. Besides, a water temperature monitoring network with small memory-type thermometers was deployed along Okinawa islands. A similar attempt to deploy a number of thermometers has been made also in the Philippines in collaboration with a group at the Marine Science Institute of the University of the Philippines. The analyses of the satellite remote sensing data and the thermometer data have been successfully utilized for the investigation of coral bleaching, which occurred worldwide including Okinawa islands and the Philippines in 1998.(3) An attempt to establish an international joint study project on coral reef - mangrove ecosystem :Through the present study, an attempt has been made to establish an international joint study project, in which the research groups of the above mentioned MSI/UP, James Cook university and Queensland university, etc. will join, for developing more integrated monitoring systems on coral - mangrove ecosystem.
