ABSTRACT:
With the development of the Earth Observation System, many Chinese satellites are launched and used, such as China-Brazil Earth
Resources Satellite (CBERS), FY series meteorological satellites, "Beijing-1 "small satellite, and so on. The paper studied the
application techniques of Chinese satellites in Russia Siberian area. The core research work is divided into 3 parts as below. (1)
Chinese satellite land use/land cover monitoring techniques research. (2) Chinese satellite regional environmental background values
extraction and parameter inversion techniques. (3) Chinese satellite regional ecological evaluation techniques. Through the 3 kinds
of techniques study and experiments validation, the paper analyzed the Chinese satellites remotely images features and discovered
some key techniques.
1. INTRODUCTION
With the development of the Earth Observation System, many
Chinese satellites are launched and used, such as China-Brazil
Earth Resources Satellite (CBERS), FY series meteorological
satellites, "Beijing-T'small satellite, and so on. Although
remotely sensed images collected from these Chinese satellites
are widely used in more and more fields recent years, they have
not been used outside China. With the development of GEOSS,
we should pay more attention to the application techniques and
capacities of Chinese satellite in other places outside China.
Russia Siberian area is suitable for this research, because this
area has not only plentiful natural resources, but also typical
regional geographical features which are sensitive to the earth's
environment change as below.
1.1 Scientific significance to the global change research
Siberian area is the hotspot area in the global change research
and Earth System Science integrated research. “Globe change
and regional response” has been taken as the basic research
facing the nation significant strategic needs in the China
National Guideline on Medium- and Long-Term Program for
Science and Technology Development (2006-2020).
1.2 Regional ecosystem security
Siberian and its south neighboring area locate at the East Asian
Monsoon area, where are sensitive to earth's environment
change. At present, the area is facing to the problems like
drying up of rivers, desertification, inadequate protection of soil
and water resources, frequently disasters, etc. All of these
compose a serious obstacle to the economic and social
sustainable development of related countries in this intersection
region.
1.3 The integrated research demand of multi-subjects
Research work in Siberian area has integrated and
multidisciplinary crossed characteristics. Many environmental
factors of global change grades have typical gradual change
character in this area. For example, the annual mean
temperature varies from -20°C to 20°C. The annual mean
precipitation varies from 100mm to 2000mm. The number of
population by per square kilometer varies less 10 to more than
1000. The level of land use varies from rare exploitation to high
intensity using, and so on. If these dynamic changes
information can be detected by remote sensing, this will help to
reveal the rules of the resource & environment and ecological
evolution and the Regional Response characteristics for multi
subjects need.
2. RELATED RESEARCH PROGRESSES
2.1 International remote sensing research and application
progress in high latitude region
Many countries have launched amounts of survey and
investigation projects or engineering on resources and
environment by means of GIS and RS techniques, such as land
use, land cover, crop yield assessment, vegetation monitoring,
soil and water quality survey and so on. For instance, United
States Department of Agriculture (USDA), National Oceanic
and Atmospheric Administration (NOAA), National
Aeronautics and Space Administration (NASA) and U.S.
Commerce Department launched a joint project for Large Area
Crop Inventory Experiment (LACIE) from 1974 to 1977. This
project monitored the wheat crop area and accessed its yields in
North America with high accuracy (over 90%). Another project
for agriculture and resources inventory surveys through
aerospace (AGRISTARS) was implemented from 1980 to 1986
which has been developed to an integrated running system.
