Malan loess is highly water-sensitive， with its shear strength， particularly cohesive strength， significantly decreasing under the influence of water. The Western Shanxi Loess Plateau （WSLP） is especially prone to loess landslides， which are closely linked to rainfall infiltration. Understanding the regional variation of Malan loess cohesion (cm) and its distribution in relation to the developmental intensity of landslides in this area can provide essential scientific evidence for effective landslide prevention. Loess landslides and Malan loess were selected as the objects of study for the current research. The regional variation and distribution pattern of the cmwere revealed through undisturbed loess direct shear tests and Inverse Distance Weighting （IDW） interpolation. The relationship between the developmental intensity of landslide and the regional variation of the cmwas explored using the Cumulative Sum Variable Dimension Fractal （CSVDF）， Frequency Ratio （FR） model， and Certainty Factor （CF） model. The following conclusions were drawn: Results from the direct shear tests and IDW method indicate that the cmtends to decrease from south to north and exhibits a positively skewed spatial distribution pattern. The CSVDF results indicates a similarity between the regional variation of the cmand the development intensity of loess landslides. The FR and CF results reveal that loess landslides are more likely to occur when the cmis between 0 and 16.14 kPa.
