The weights of evidence（WofE）model was applied to study the habitat suitability assessment of Red-crowned Crane in Zhalong．The evidence factors involves land-use types，vegetable types，railway buffer, national highway buffer and residential area buffer，which were derived from maps based on RS and GIS spatial analysis. Calculated weights for each predictive map or evidence map , and conditional independence were tested to identify the maps. Combining the evidential themes to create a posterior probability theme. An objective assessment of habitat suitability provides a rational basis for management decisions incorporating impact on species habitat. WofE model was proven suitable to generate spatial habitat species occurrence relationships..Hence WofE may constitute an effective tool that combines spatial data to describe and analyse interactions among evidential themes while providing support for decisions makers.
