Abstract

This research defines the savanna aeolian landscape dynamics of the ‘Santos Luzardo’ National Park in the Llanos of Venezuela between 1988 and 2018, using images from the LANDSAT series to elaborate and compare ecosystems maps. The ecosystem dynamics show that the landscape changes naturally since the transitions occurred towards other types of natural savanna due to soil water seasonality. The savannas are the dominant matrix of the landscape, occupying between 69.1 and 76.7%. The dynamics of transformation of the aeolian savanna landscape are mainly associated with soil water content. The application of temporal studies contributes to understanding the aeolian savanna landscape transformation processes and evaluating their conservation status.

摘要

这项研究使用 LANDSAT 系列图像来详细说明和比较生态系统地图，定义了 1988 年至 2018 年间委内瑞拉亚诺斯“桑托斯卢扎多”国家公园的稀树草原风沙景观动态。生态系统动态表明，由于土壤水季节性向其他类型的自然稀树草原转变，景观自然发生变化。稀树草原是景观的主要基质，占 69.1% 至 76.7%。风沙稀树草原景观的变化动态主要与土壤含水量有关。时间研究的应用有助于了解风沙稀树草原景观转变过程并评估其保护状况。
