Abstract: Based on remote sensing and GIS technique, combined with the field survey, took advantage of scenarios study approach and making-decision system of landscape ecology, aimed at issues that water shortage in the Yellow River Delta (YRD) wetlands caused deterioration of eco-environment, then formulated three restorationscenarios to wetland water demand. These scenarios are respectively current situation in 2005, restoring southern nature reserve (scenarios A), and restoring south-north nature reserve (scenarios B). Different water supply schemes are set up under each scenario. The evaluation on each scenario to suitability of indicator species shows that current wetlands of the YRD is for the habitat of rare bird with poor quality; Scenario A2 takes reed marsh as main breeding habitat where is most suitable for Oriental Stork (Ciconia boyciana) with increased area of 8307 ha, but no big change in suitable habitat coverage for Sauder¡¯s gull (Larus saundersi). Scenario B2 habitat coverage is most suitable for Oriental White Storkwith increase of 12035 ha in area, and 298 ha for Sauder¡¯s gull habitat coverage. This shows that two typical habitats, viz. reed marsh and Seablite tidal flat,will improve mostly via restoration. Comparing different scenario, scenario B is best one in ecological effect.
