Interpreting the three types of wetlands ( riverine wetlands , lacustrine wetlandsand flood-plain wetlands ) of Maduo county in the Yellow River Source Zone utilizingTM images and using 1990, 2001 and 2013 three periods.The research result showsthat wetlands decreased 361.03 km2 from 1990 to 2001 , of which floodplain wetlandsdecreased the most , followed by lacustrine and riv-erine;whereas from 2001 to 2013 thearea of wetlands increased 289.51 km2 , lacustrine wetlands ar-ea increased most andfollowed by floodplain wetlands and riverine wetlands .From 1990 to 2013 the area ofthree kinds of wetlands appeared declining trend which totally decreased 71.52 km2 in recent 20 years, the three kinds of wetlands in Maduo county have appeared firstdecreased and then in-creased trend .
