自前哥伦布时代以来，哥伦比亚经历了大部分自然生态系统的转变，特别是在安第斯地区。迄今为止，人们对这种转变的模式和过程及其与社会经济和生物物理方面的关系知之甚少。传统上，缺乏多学科数据的整合阻碍了理解这样复杂现象的可能性。综合方法有助于将通常单独分析的数据纳入相关的上下文分析。本文提出了一种理解生态系统转型的方法，通过在空间上将生态系统分布和转型的数据与全国范围内的人口、土地利用和定居历史数据联系起来并进行整合。为了解释目前的情况，并对未来的趋势作出一些一般性的预测，转换进行了分析和记录。结果表明，人口和转型模式遵循明确的历史趋势，可以在空间上区分，并与自然区域平原和山区，海拔带和一般的土地利用。特别是，安第斯山脉和低地的格局显示出历史上不同的趋势。安第斯地区的人口密度和转型比例高于低地。较老的定居区显示出较高的密度和较密集的土地使用，往往与安第斯地区有很大的联系。
Abstract Since pre-Columbian times, Colombia has undergone transformation of large parts of its natural ecosystems, in particular in the Andean region. To date, little is known about the patterns and processes of this transformation and their relation with socioeconomic and biophysical aspects. Traditionally, the lack of integration of multidisciplinary data has hampered the possibility to understand complex phenomena like this. An integrated approach helps to bring into a relevant contextual analysis, data that are normally analyzed separately. This paper presents an approach to understanding ecosystem transformation by linking and integrating, spatially, data on ecosystem distribution and transformation, with demographic, land use, and settlement history data on a national scale. The transformation is analyzed and documented in order to explain the present situation and to make some general predictions about future tendencies. The results show that the demographic and transformation patterns follow clear historical trends that can be spatially differentiated, and are related to natural regions—plains and mountains, and altitude belts—and to general land uses. In particular, the patterns of the Andes and the lowlands show historically distinct tendencies. The Andean region has higher densities and transformation proportions than the lowlands. The older settlement areas show higher densities and more intensive land use, and tend to be strongly related to the Andean region.
