Examining eco-environmental changes at major recreational sites in Kenting National Park in Taiwan by integrating SPOT satellite images and NDVI

Abstract

The integration of remote sensing data and vegetation indices can enable the investigation of dynamic changes in ecological environments. This study utilized SPOT satellite images from different periods as raw materials and combined geographic information system (GIS), normalized difference vegetation index (NDVI), and related statistical analyses to examine the condition of the ecological environment at the main terrestrial attractions of Kenting National Park in Taiwan. The results showed that changes in the ecological environment at the main attractions are presented to varying degrees on spatial-temporal scales. The changes are also relevant with respect to the numbers of artificial facilities and tourists. Moreover, change analysis via RGB WFM (write function memory insertion) can create spatial layouts for management. Well-conserved natural resources for sustainable development play a key role in attracting tourists. This study's investigation of the change in the main terrestrial attractions in the ecological environment of Kenting National Park may facilitate the preservation of natural resources.
