“…La importancia de los humedales recae como se ha mencionado, en que son ecosistemas acuáticos cubiertos de agua dulce, salada o salobre, estancada y con movimiento, permanentes o temporales, naturales o artificiales; debe tener vegetación acuática y suelos cubiertos por agua (Lobo, 2014), lo que de acuerdo con Zhao et al, (2018) resulta de mucha importancia monitorear y evaluar la dinámica de este ambiente ecológico, con respecto al desarrollo de las actividades humanas agrícolas y pecuarias. Estudios realizados por de Melo, Campos, Brown, Chiquitelli y Carvalho (2018) han utilizado con gran suceso diferentes tipos de herramientas para explicar fenómenos complejos y dar un enfoque integral a estos trabajos.…”

El objetivo de esta investigación es analizar la situación de la frontera agrícola y sus implicaciones en la sostenibilidad del ecosistema mediante la actualización del uso del suelo en las áreas aledañas al Humedal Nacional Térraba Sierpe (HNTS), para esto, fue necesario la utilización de técnicas de teledetección, giras de campo, revisión bibliográfica, y herramientas electrónicas como DNR Garmin y Arc Gis 10. Algunos de los resultados arrojan que la producción agropecuaria continúa siendo la principal actividad económica, destacando la producción de arroz, palma africana, plátano y ganadería de carne, estas actividades se practican como monocultivos o ganadería extensiva sin respetar de los límites de protección al HNTS, poniendo en riesgo la frontera de amortiguamiento.

“…Remote sensing technology has gradually become an important tool for ecological monitoring due to its advantages, such as a large coverage area and short data acquisition period [8,9]. Remote sensing monitoring involves obtaining long time series of land use, vegetation cover, temperature, and humidity index, which are important in comprehensively evaluating the ecological environment [10].…”

Analyzing human–environment coupling is important in understanding the mechanisms and developments of human–environment systems. However, the current frameworks and approaches evaluating the relationship between human activities and the ecological environment remain limited. Integrating the vegetation-impervious surface–soil–air framework, Mann–Kendall test, correlation analysis, two-step floating catchment area method, coupling analysis, and optimal parameters-based geographical detector, this study comprehensively evaluate the environmental changes and analyzes the coupling relationship between environment and human activities, mainly in terms of habitat quality, landscape pattern, and ecological services. The study area was the Qilian Mountain National Nature Reserve in Gansu province, China, an ecologically fragile region with an environment closely linked to human activities. Along with district and county census data, various remote-sensing products (e.g., MODIS, Landsat) were used to assess the ecological level and human–environment coupling state of the study site from 2003 to 2019. The main results show: (1) The remote sensing composite index, which integrates eight ecological sub-indices, effectively captures the spatial and temporal variations of the ecological environment in the study area, providing comprehensive and detailed environmental information. (2) Analysis using the Mann–Kendall-correlation classification, coupling degree, and two-step floating catchment area methods consistently demonstrates a gradual coordination between human activities and the ecological environment in the study area. (3) In comparison to spatially interpolated population data, the remote sensing human activity index more significantly represents the spatial impact of human activities on the ecological environment. (4) The environmental aspects most strongly associated with human activities include carbon fixation and oxygen release, vegetation, humidity, and soil. (5) The ecological environment level does not uniformly deteriorate with increasing population density, and a notable alignment is observed between changes in the ecological environment and the implementation of government environmental protection policies.
