Integrated remote sensing inventory of the Three-North forest shelter belts
The Three-North implys the region which composed of three sub regions: north-east, north, and north-west of China and covers above 3.89 million sq. km as for almost 40 percent of the country’s territory. The ecological environment in this region is quite sensitive with serious problems of soil erosion and desertification. The purpose of this project is to inventory forest and land resources in the region, mation system for regional planning, and evaluate the impact of forest shelter belts constructed on ecological environment based on the inventory. Three levels of thematic maps with scales of 1:10,000, 1:500,000, and 1:1500,000 including landuse map, forest type map, grass type map and land suitability map will be produced. A typical country was selected as the test area for evaluation for capabilities of different types of remote sensing data such as TM, MSS, SPOT, and aerial IR images of different tasks before overall investigation started. This project has been carried on jointly by researchers from institutes of Ministry of Forestry and Chinese Academy of sciences (CAS), and universities.

Investigation of soil erosion in the Loess plateau
The project is to use multi-level remote sensing information for producing maps of landuse and soil erosion intensity of this region, and put forward a proposal for controlling soil erosion and planning of the region. A geographical information system is a very important content of this project. Many scientists from institutes of CAS, Ministry of Agriculture, and Universities have involved to this project.

Exploration of mineral deposits
Several mine prospective areas have been found, such as gold, coal, oil and gas, by scientists of CAS and Ministry of Geology and Mineral Exploration using satellite and airborne remote sensing images integrated with geochemical and geophysical data. Researchers are intending to use new airborne remote sensors, such as fire-split infrared scanner, for mineral exploration, and some remarkable results have obtained in the Xinjiang Autonomous Region.

Forest fire monitoring
Both the meteorological satellite center and the remote sensing ground station in Beijing received NOAA and TM Images of the Daxingnagling forest north-east part of China to monitor and evaluate the current status ad development trend of the fire for making correct decision in fire-fighting. It has proven that remote sensing is very helpful in forest fire fighting.
- Flood monitoring
Satellite remote sensing information has been applied to monitoring flooding of the Laiohe River, the Nenjiang River in Northeast China, Yellow river and Yangtze River. The Meteorological satellite with fast cycle time show obvious advantages for flood monitoring. We also use aerial SAR remote sensing for all weather monitoring the flood of rivers, transmit image data to headquarter of flood-fighting in Beijing by communication satellite and microwave communication links, and build an information system to calculate area of indundated land, and to estimate the loss caused b the flooding. A flooding control system for the Yellow River, including flood forecasting, monitoring, management of river bed and dykes, and alarming sub-systems, is under development.
