Paper Abstract

The cultivated land protection has become a leading concern influencing the actions of the Chinese government and people. This study introduces a method named as the weight of evidence (WOE) using natural and geographical location factors to evaluate the suitability of Jinan cultivated land. Evaluation results show that: (1) weight of evidence method as a pure data-driven approach is suitable for confirming each index’s weight in the cultivated land suitability evaluation, and the weights are objective and easy to be explained; (2) weight of evidence method uses raster data which are convenient for spatial analysis and does not need to unify the evaluation unit; (3)About 60.25% of land in Jinan has superior suitability as cultivated land. The technical ideas and methods proposed in this paper can provide support for taking a fresh look at land suitability evaluation and policy making. It will also help decision-makers optimize land allocation and make better land-use planning decisions.
