Analysis on Land Suitability for Maize and Rapeseed Production Based on Data Mining Method—A Case Study at Zunyi City, Guizhou Province
[Objective] Conducting multi-crop land suitability analysis was carried out in order to provide an accurate and effective method for crop planning
land use planning
and management of agricultural production.[Methods] Based on data mining method
the comprehensive suitability of multi-crop land was quantitatively characterized by a random forest algorithm
a comprehensive index evaluation method
spatially constrained multivariate clustering
and spatial statistics.[Results] ① A random forest algorithm quantitatively and accurately produced the spatial layout of crop planting driven by multi-spatial elements
and identified factors that had a key influence on the selection of suitable planting land for maize and rapeseed. ② The suitable areas for maize and rapeseed planting exhibited significant spatial heterogeneity in the study area. The suitable areas for maize accounted for 91.23% of the total planting land area
but the suitable areas for rapeseed accounted for only 69.64%. The areas suitable for the planting of both crops was 13.08% of the total area
and were mainly located in the central and north parts of Fenggang County
the north part of Meitan County
and the northwest part of Yuqing County.[Conclusion] Data mining provides the possibility of selecting the optimal planting land use pattern. The method used in this study has good potential for evaluating the suitability of land in many locations for the production of various crops.
