英文摘要Spatial rough set theory is an extension of classical rough set theory that is designed to handle spatial data. Different from its classical analog, spatial rough set theory approxi-mates nominal target variables in each local region, thereby enabling the local explanatory power of various factors on these nominal target variables to be determined. Based on spa-tial rough set theory, this paper describes two new uncertainty indices for measuring the spatial heterogeneity of the local explanatory power on nominal target variables. Moreover, three new spatial rough set-based geographical detectors are proposed. With the help of the uncertainty indices, these detectors measure the spatial explanatory power of different factors, compare their importance, and detect feature interactions. Experiments are conducted using two publicly accessible datasets to demonstrate the effectiveness of the proposed geographical detectors and evaluate their performance against that of geo-graphical detectors based on q-statistics. The results show that the proposed detectors are effective in processing nominal variables and can be used to complement existing q- statistics-based geographical detectors.(c) 2021 Elsevier Inc.
