摘要：
In the environment of land space big data, the performance of spatial development suitability evaluation based on serial superposition analysis has reached the extreme. In order to use more computing resources to improve the efficiency of spatial development suitability evaluation, it is necessary to study the parallelization method. Based on overlay analysis for multi factor of the principle of comprehensive evaluation, the spatial data preprocessing method, spatial data partition method and parallel spatial index are introduced, and the spatial development suitability evaluation based on parallel overlay analysis is realized. The application of this method in the suitability evaluation of space construction land in four provinces in Southwest China breaks the situation of low efficiency or incompetence in large-scale calculation under the traditional framework, and the efficiency has increased more than 30 times. © 2021, Editorial Department of Journal of Northeastern University.
