In recent twenty years, large-scale exploitation and increasing human activities in the Yellow River Delta Nature Reserve have brought rapid economic development. Despite that, the ecological system encounters the enormous pressure. Therefore, studying on the drawing and implementation of ecological sensitivity redline plays a significant role in preserving and restoring the ecological environment. Taking the Yellow River Delta Nature Reserve as the research object, this study initially distributed the Nature Reserve into different land parcels according to various land use, then the expert scoring method was utilized to evaluate the degree of land development and the habitat complexity of each land parcel. And then the Nature Reserve was classified by constructing land use and development degree and eco-environment complexity judgment matrix. Finally, GIS technology was applied to realize the delineation of important control area, moderate control area and general control area. The result shows that the three areas occupy 256.53 km(2), 567.04 km(2) and 193.16 km(2) respectively, accounting for 25.23%, 55.77% and 19.00% of the total area separately. Implementation includes to establish the zoning control system, to set up the information management GIS database and improve the monitoring system, and to build the ecological restoration laws and emergency management regulations and the like.
