To strengthen slopeland conservation, the Classification Standard of Slopeland Utilization Limitations was promulgated in 1976. Based on average slope, soil depth, soil erosion degree, and parent rock, this standard classified slopelands into land suitable for agriculture and animal husbandry, land suitable for forestry purposes, and land subject to strengthened conservation on one single cadastre that leads to the fragmentary of Limitation Classification of Slopeland Utilization (LCSU) results. We aimed to establish a regional concept for the LCSU method, which combined the slope unit and KDE of flat land (average slope < 30%). The results revealed that the proposed regional concept for the LCSU method avoided the LCSU fragmentation. Cadastres of slopeland in Chiayi County were in agreement with the regional concept for the LCSU with a fitness of >75%. An amending assessment was also conducted to adapt the regional concept for the LCSU under different thresholds.
