为了研究厄瓜多尔北部亚马逊地区殖民者和土著人口在土地利用和环境影响方面的差异，我们结合了来自64个殖民部门的778个殖民者家庭和36个社区5个土著群体的499个家庭的家庭调查数据和遥感图像。总体而言，殖民者的毁林和森林破碎程度明显高于土著人民。平均而言，殖民者家庭的农业和经济作物面积约为土著家庭的两倍，牧场面积约为土著家庭的5.5倍。然而，五个土著群体的土地使用模式在牛的所有权和雇用农业劳动力的使用等方面存在很大差异。这些发现支持了土著土地的潜在保护价值，同时警告人们不要采取使土著民族同质化的统一政策。
To examine differences in land use and environmental impacts between colonist and indigenous populations in the northern Ecuadorian Amazon, we combined data from household surveys and remotely sensed imagery that was collected from 778 colonist households in 64 colonization sectors, and 499 households from five indigenous groups in 36 communities. Overall, measures of deforestation and forest fragmentation were significantly greater for colonists than indigenous peoples. On average, colonist households had approximately double the area in agriculture and cash crops and 5.5 times the area in pasture as indigenous households. Nevertheless, substantial variation in land-use patterns existed among the five indigenous groups in measures such as cattle ownership and use of hired agricultural labor. These findings support the potential conservation value of indigenous lands while cautioning against uniform policies that homogenize indigenous ethnic groups.
