本研究的目的是评估牧场的荒漠化风险，在三个村庄社区的Lagadas县，北方希腊，利用地理信息系统（GIS）。使用地理信息数据是为了将涉及荒漠化的几个层次的信息联合收割机结合起来，形成一个地理信息系统模型。后一种方法是对环境敏感区制图方法的修改。结果表明，研究区大部分地区处于荒漠化的关键阶段。大部分牧场都在进行密集的放牧活动。然而，过度放牧与土壤、植被和气候等物理参数相结合，加剧了荒漠化的风险。
The aim of this study was to evaluate the desertification risk of rangelands in three village communities of Lagadas county, northern Greece, with the use of the Geographic Information Systems (GIS). Geoinformation data were used in order to combine several layers of information involved in desertification for the formation of a GIS model. The latter is a modified approach of the methodology used for mapping Environmentally Sensitive Areas (ESAs). It is found that the majority of the study area is in a critical stage in terms of desertification. The majority of rangelands are under intensive grazing activities. Overgrazing however, contributes to the desertification risk in combination with physical parameters such as soil, vegetation and climate.
