Minimum Cumulative Resistance Model

The minimum cumulative resistance (MCR) model is based on the "source-sink" theory. The minimum cumulative resistance refers to the cost or work done by the extension subject to reach the destination (sink) from the source through the landscape impedance of different resistances, reflecting a potential accessibility. The minimum cumulative resistance model takes the mutual transformation of different landscape types and the change of landscape pattern as landscape elements through overcoming resistance, reflecting the trend of spatial movement of landscape elements. The minimum cumulative resistance model can be used to establish the resistance surface. The model considers three factors: source, distance and landscape medium characteristics, and the most critical process is how to determine the spread source and the resistance coefficient.
