Abstract
The source area of the Yellow River is characterized by complex climatic and geomorphological conditions, fragile ecosystems, and a series of ecological and environmental problems. At the same time, the region is an important ecological barrier area in China, which is related to national ecological security. The construction of ecological and risk networks is indispensable for maintaining ecological processes and sustaining ecological harmony. Based on ordered weighted average operator, morphological spatial pattern analysis, ecological sensitivity, circuit theory, CA-Markov model, kernel density analysis, and other methods, this study aims to consider the positive and negative connections of the network thus constructing the ecological and risk network and predicting the potential risk areas in the future. It provides guidance, reference and early warning for ecological protection and restoration in the Yellow River source area in order to promote ecological high quality and sustainable development.
