Abstract:: In view of the major ecological environmental problems in the Qilu Lake Basin, we selected eight ecological safety assessment indicators, i. e., slope, altitude, vegetation coverage, land cover type, distance to water surface, distance to other construction land, and distance to residential area, to assess the ecological security of this basin using the comprehensive index method, entropy method, and GIS technology. The results indicated that:(1) the average eco-safety index of the Qilu Basin was 2.59 and the ecological safety was mainly based on lower safety, accounting for 36.33% of the total area of the river basin, followed by moderate safety and insecurity, accounting for 23.36% and 22.53% of the total basin area, respectively; the safest area was the smallest, accounting for only 17.77%; the lower safety zones mainly distributed in the northwest, southeast and southwest, and ecological protection construction in these areas should be strengthened; (2) through the research on the ecological security of the basin and its variation characteristics in factors, it was shown that the lower security was dominant in the areas with smaller slopes and lower elevations; forest lands were mainly based on high security, and the construction area had the largest proportion of unsafe areas; the greater the distance between other construction land, residential areas and roads, the greater the area of ecological insecurity, and the lower the ecological security; (3) the ecological security of the river basin was affected by a variety of factors; there were mutual promotion and mutual inhibition between the factors; vegetation coverage, land covers types, distance to other construction land, distance to residential sites, distance to roads and distance factors had the significant impacts on ecological security.
