全球陆地生物多样性受到土地使用扩大、气候变化和氮沉降的强烈影响。这对热带森林尤其如此，因为热带森林已经显示出主要由于土地使用活动而发生的巨大变化。在上一个世纪，厄瓜多尔土地利用的程度大大增加。一个广泛的一级和二级公路网现在使该国西部和中部大部分地区变得畅通无阻，而东方的部分地区已变成保护区。在气候变化方面，预计厄瓜多尔西部的变暖程度将是温和的，而该国东部将遭受气温上升的影响，这将影响到一个拥有全球维管植物物种多样性热点之一的植物区系地区。预计降水量的变化在空间上的凝聚力要小得多，降水量的增加和减少在整个安第斯山脉分布不均匀。降水和风的空间分布和时间动态也调节了亚马逊河流域生物质燃烧导致的山区生态系统中雨水溶解物质的沉积。在本章中，我们目前的知识，这些主要威胁的生态系统的过去发展将讨论重点研究区域南厄瓜多尔。
Global terrestrial biodiversity is strongly affected by expanding land use, climate change and nitrogen deposition. This holds especially true for tropical forests which already show large changes due mainly to land use activities. The extent of land use in Ecuador has increased considerably during the last century. An extensive network of primary and secondary roads now opens up most of the western and central areas of the country, while parts of the Oriente have been converted into protected areas. Concerning climate change warming is predicted to be moderate for western Ecuador, while the eastern part of the country will suffer from rising temperatures that will affect a floristic region harbouring one of the global diversity hotspots for vascular plant species. Changes in precipitation are expected to be spatially much less cohesive, with increasing and decreasing amounts of precipitation being unevenly distributed throughout the Andes. The spatial distribution and temporal dynamics of precipitation and wind also regulate the deposition of rainwater-dissolved matter in the mountain ecosystem which results from biomass burning in Amazonia. In this chapter, our current knowledge as to the past development of these major threats of the ecosystem will be discussed focusing on the study area South Ecuador.
