摘要
对赤潮遥感信息及同步采集的赤潮优势种类的光谱数据与同步采集的生物、化学、水文、气象等相关观测数据作了分析,在VisualFoxpro集成系统环境下,研究了地物光谱数据处理算法,以及利用地物光谱数据提取赤潮优势种类等生物信息的方法,并阐述了赤潮生物优势种类识别和赤潮生物特征量分析的应用及赤潮生物的监测。
Based on remote sensing information of red tide organisms and the related data collected simultaneously, such as the spectrums, the observation data of biology, chemistry, hydrography and meteorology, the database algorithmic functions for the data processing of ground object spectra and that for the extraction of the predominant species of red-tide organisms as well as related biological information from ground object spectra are developed in the environment of the integrated Visual FoxPro System. Furthermore, an application system is constructed for the detection of the boom of red-tide organisms, the recognition and identification of the predominant species of red-tide organism, and the analysis of their characteristic values. The flow chart of management and the main functions of the system are described, the design of the system construction and the realization of each module of the system are depicted, and analysis of some application cases of the system is provided. The system under consideration can provide effective tool for marine environmental protection and for the researches on the reduction of red-tide disasters, and can also provide quantified object data for the govermment departments (in charge) of natural resources and environmental administration.
