Abstract:

In view of the characteristics of present ecological meteorology service and the requirements of operation，a ground observation，analysis and evaluation system written in c and c++ language for ecological meteorology have been established.The designed goal，principle and the structure of this system，the main function and technical methods，etc are introduced.The swap files output from the program can be statistic analyzed in detail，and a series of graphics drawing methods such as contours plots and region shaded plots were also provided.The AVHRR and EOS/MODIS satellite remote sensing (RS) data can be processed.The interpretation，classifying and quality control of meteorological observations could be carried out.The program was designed to analyze index of water density，moisture index，vegetation index，land degradation，disaster index and ecological meteorology and evaluation index etc.In this program，the products of ecological meteorology monitor evaluation were exported in the form of figure or image，and the effective organization and management of the satellite remote sensing data and ground observation data of eclogical meteorology could be realized.The system has been applied on ecological meteorology and evaluation service of Hunan Province，and the result indicated its perfect service practicability.
