Abstract: Water and sand had been regulated and controlled in the whole Huanghe watershed since 1999. In 2002 wetland restoration engineering began to done in order to protect and restore the wetland ecosystems of nature reserve of Yellow River Delta. Use Landsat archive images (acquired on Aug. 28, 1999, on Aug. 9, 2001, on Oct. 28, 2004, on July 11, 2005, and on Oct. 2, 2006) and HJ-1B CCD data (acquired on Oct. 2, 2008) to monitor the dynamic land use/land cover changes (LUCC) of nature reserve of Yellow River Delta. The present results show that the image quality of HJ-1A/B CCD data is similar to that of Landsat TM, which is explicit enough to meet the needs for monitoring LUCC, and with wetland restoration engineering, wetland development and utilization increasing only 14.95% of Suaeda meadow, 39.96% of Chinese tamarisk shrubs, 22.21% of Reed swamp and 3.77% of Reed meadow had kept no change in the recent ten years, and in 2001 and 2004 landscape fragmentation was relatively severe, and to 2004 the relatively unchanged areas of four types of natural vegetation communities were rapidly decreased, and in the recent ten years the regions in which the inverse succession happened were 2.07-fold that of progressive succession, which reflected ecological fragility of Yellow River Delta. Scientific managements on wetland ecosystem of nature reserve of Yellow River Delta should be done.
