摘　　要： 1遥感应用实验的历史经验 20世纪末,在中国南方热带、亚热带地区,由原国家科委、科技部和中国科学院先后组织过多次大型遥感应用实验.例如,海南岛三次航空遥感系列专题制图(1963),一次富铁遥感找矿(1972),腾冲资源遥感(1978),二滩、龙滩水电站工程地质评估(1980)、洞庭、鄱阳湖洪涝灾害监测(1991,1998),三峡生态移民(1990-),广东鼎湖山自然保护区生物地球化学指示植被(1987),SIR-CR-SAR生态与环境综合分析(1997)、香港、航空微波遥感实验飞行与城市环境太空影像地图集编制(1999)等. The Pacific and Indian Ocean monsoons bring abundant precipitation and seasonal high-temperature and heavy cloud. Cloud makes great difficult for data acquisition with visible light remote sensing. Every year typhoons bring great destruction on forest, hills, transportation, communication and power networks. So multispectrum and microwave remote sensing are strongly needed. Species resource is greatly abundant in South China. Classifications of coral, mangrove and other plants with remote sensing need special image processing technologies. Species identification is very difficult and needs abundant geobotanical, biological knowledge and field survey data. In South China, the strong efflorescence and simultaneous physical and chemical corrosion result in unique red sandstone topography （Danxia dimao） and karst topography. For example, in tropical monsoon forest, nanmu and agallochum can only be found in remotely sensed images when they blossom transitorily. Fish groups location can get support with identifying the interface of cold snap and warm current, and migration of birds.
