Wetland is a special ecosystem between land and water . It can provide massive foods, raw material, water resources
and habitat for human being, animals and plants, Wetlands are so important that wetlands' development, management
and protection have become the focus of public attention ."3S" integration technology was applied to investigate wetland
resources in Shandong Province ,the investigation is based on remote sensing(RS) information, combining wetlandrelated
geographic information system(GIS) data concerning existing geology, hydrology, land, lakes, rivers, oceans and
environmental protection, using the Global Positioning System (GPS) to determine location accurately and
conveniently , as well as multi-source information to demonstrate each other based on "3S" integration technology. In
addition, the remote sensing(RS) interpretation shall be perfected by combining house interpretation with field survey
and combining interpretation results with known data.By contrasting various types of wetland resources with the TM,
ETM, SPOT image and combining with the various types of information, remote sensing interpretation symbols of
various types of wetland resources are established respectively. According to the interpretation symbols, we
systematically interpret the wetland resources of Shandong Province. In accordance with the purpose of different work,
we interpret the image of 1987, 1996 and 2000. Finally, various interpretation results are processed by computer
scanning, Vectored, projection transformation and image mosaic, wetland resources distribution map is worked out and
wetland resources database of Shandong Province is established in succession. Through the investigation, wetland
resource in Shandong province can be divided into 4 major categories and 17 sub-categories. we have ascertained the
range and area of each category as well as their present utilization status.. By investigating and calculating, the total area
of wetland in Shandong Province is 1,712,200 hm2,which accounts for 7.58% of the total area of land in Shandong
Province (not including the wetland in the shallow waters along the coast). Among them, area of river wetland is
286,746 hm2, area of lakes wetland is143,490 hm2, area of reservoir and pond wetland is 118,693 hm2, area of offshore
and coastal wetland is 994,100 hm2, and area of other wetland is 169,171 hm2. On the basis of this, we can analyze the
dynamic changes trend and the reasons: steady degenerating for natural wetlands, increasing year by year for artificial
wetland, and the distribution pattern takes shape that the existing natural wetlands are being protected and the increase of
new artificial wetlands is in conformity with the social development, so the situation of the wetland resources is
developing towards a virtuous circle direction.
