The karst and its neighbors: Digital map of geomorphic environments in Quintana Roo, Mexico

[摘要] The Yucatan peninsula is a large, carbonate platform with several geomorphic environments, the largest of which is thekarst. The other geomorphic environments have not drawn much scholarly attention. The objective of this work is to spatiallyidentify the geomorphic environments found in Quintana Roo, Mexico. These environments were characterized anddefined through their geomorphic and environmental conditions, such as climate and vegetation. The soil types associatedwith them using cluster statistical analysis, principal components and classification analysis, processed through a GISsystem. Seven geomorphic environments were defined for Quintana Roo based on their geomorphological characteristicsand types of coverage: littoral, paludal, pseudopaludal, tecto-karstic, karstic, gypsum karst and mixed karst, with 12 subtypes.The karstic and tecto-karstic geomorphic environments occupy the largest surface. The digital map (1:50,000) ofgeomorphic environments that resulted from this investigation has an accuracy level of more than 80%, which makes it animportant tool for developing plans and strategies for the use and management of land in Quintana Roo.
