Resumen:
The unsustainable use of natural resources has contributed to the
deterioration of ecosystems, loss of biodiversity, and degradation of
soils in Mexico. In the state of Tabasco, environmental deterioration is
evident in the chemical and physi-cal degradation of soils. In this
context, geomor-phological mapping can contribute to mitigate this
problem by generating a geospatial framework for land use planning, and
to provide guidance for the use and management of natural resources.
Howe-ver, this information on a micro-regional level is scarce. The aim
of this work was to generate a detailed mapping of landforms in plains
and hills with agricultural use in the municipality of Huimanguillo,
Tabasco, in an area of 29 398 ha. The first phase of the geopedological
approach was applied and we generated maps of geomorphological
landscapes, relief/modeling, lithology/facies, and landforms performing
a morphographic and morphometric attributes analysis. The analysis was
complemented with photointerpretation of orthophotomaps and field
verification. Forty-nine percent of the study area corresponds to the
geomorphologic landscape of plains, containing floodplain reliefs and
depres-sions over alluvial sediments, with the prevalent landforms of
river levee, overflow mantle, and decantation basin. These have good
surface drainage, except for the basins that stay flooded for six
months. The remaining area belongs to the geomorphological landscape of
hills, with hillocks and depression reliefs over detritic sediments,
with dominant landforms of backslope, summit, inter -hill depression,
and foot slope. New landforms were zoned as inter-hill depression,
teardrop, shoulder, and oil well. Depressions in elevated topographic
positions stand out for having floo-ded wetlands for up to eight months.
The study provides information that can contribute to the planning of
agricultural and forestry land uses, in order to mitigate the
degradation of natural resources in tropical plains and hills.
