Assessing habitat vulnerability, ecosystem change trends and ecological indicators for diversity conservation in PU Mat National Park, Nghean, Vietnam

Abstract

The study's primary outcome is an assessment of habitat vulnerability and ecosystem change trends based 
on an analysis of the effects of environmental hazards, socioeconomic variables, and natural processes in the 
surrounding areas of Vietnam's Pu Mat National Park. Six indicators from four groups indicators of vegetation 
cover, topography variables (elevation, slope), meteorological factors (dryness), and demographic factors (population 
density)—were used to estimate the vulnerability of the habitat using GIS technologies and the AHP method. The 
results on the trend of ecosystem change to 2030 are determined using the MOLUSCE algorithm in QGIS based 
on the map of ecosystem distribution in 2010 and 2020 and the major factors affecting the natural and socio
economic conditions, including terrain elevation, population density, distance to roads, distance to rivers and 
streams. On the other hand, the linear connection between the influencing factors is also calculated, evaluated, and 
noticed with the positive linear connection, and the negative linear connection. These are to protect, use the 
ecosystem, and preserve biological diversity in this research area.
