Abstract
The convergence of conventional agriculture, real estate investments and sand and gravel mining characterize Calimaya as one of the most negatively impacted municipalities of the Mexican altiplano by anthropic activities. The objective of this work was to analyse the geographical and environmental context of land use and land cover change (LULCC) processes in this Municipality. For this, the following indicators were estimated: the cover change rate proposed by Food and Agriculture Organization of the United Nations by using the land cover classes proposed by the Intergovernmental Panel on Climate Change. LULCC in the last decade (2010-2019) were: deforestation and advancement of potato crop in the Nevado de Toluca Flora and Fauna Protection Area; decrease in the process of occupation of cropland areas by settlements; and, soil degradation in abandoned mines.
传统农业、房地产投资和砂石开采的融合使Calimaya成为墨西哥高原上受人类活动影响最严重的城市之一。这项工作的目的是分析本市土地利用和土地覆盖变化过程的地理和环境背景。为此，估计了以下指标：联合国粮食及农业组织利用政府间气候变化专门委员会提出的土地覆盖类别提出的覆盖变化率。LULCC在过去十年（2010-2019年）的情况是：Nevado de Toluca动植物保护区的森林砍伐和马铃薯作物的发展；减少定居点占用耕地的过程；以及废弃矿山的土壤退化。
