| Abstract: | China covers vast territory. Its annual mean precipitation is very unevenly distributed from a region to another, and from a year to next year, this is one of the main reasons for the occurrence of natural disaster, such as: flooding drought, soil erosion, landslide, mud-rock flow and so on. In order to protect the natural environment and to prevent the natural disaster extension, we urgently need to Clarity the dynamic Changes, spatial distribution and quality of water resources. No doubt, remote sensing is an effective means to answer these questions with quick response.Remote sensing data acquired by satellite and airborne surveys provide an authentic source of information for surveying identifying classifying mapping and monitoring of water resources. Multiband and multidate satellite imagery and aerial photographs have been extensively used in China for water resource studies and management. The increasing needs for water resources and environmental management have significantly promoted the development of remote sensing technology in hydrology in China. The application and technology of remote sensing in hydrology has got remarkable progress in the past years. Compare with developed countries, several projects of remote sensing applications and technology still have some backward. A brief introduction present the potentiality of remote sensing for hydrology in the new generation.Share of experience in development of remote sensing application and technology is beni-ficial to scientists of China. |
