Abstract

ABSTRACT Tree plantations have expanded rapidly during the last decades, specially in Asia and South America, and Chile has shown one of the largest increases in tree plantations in the world. The aim of this study was to analyze the dynamic and factors statistically associated with the expansion of tree plantations in two coastal basins in south-central Chile. We used logistic regression and a multimodel inference approach to assess the association of 13 location factors with tree plantation expansion in two periods (1987–2001; 2001–2015). The area of tree plantations increased by 292% and 196% in the Budi and Lingue basins, respectively. The presence of agriculture fields before conversion to tree plantations showed the greatest effect in both basins, followed by the suitability of the soil for forestry. Likewise, tree plantations were highly associated with the replacement of native vegetation, contributing to ongoing deforestation, and changes in forest policy increased the expansion in indigenous land.

智利中南部两个沿海河流流域人工林扩张的区位因素和动态:土地利用规划的基础

摘要在过去的几十年里，植树造林迅速扩张，特别是在亚洲和南美洲，智利是世界上植树造林增长最快的国家之一。本研究的目的是分析智利中南部两个沿海盆地植树造林扩张的动态和统计相关因素。我们使用逻辑回归和多模型推理方法来评估两个时期（1987–2001；2001–2015）13个位置因素与植树造林扩张的关系。布迪和林格盆地的植树面积分别增加了292%和196%。在两个流域，在转变为植树造林之前，农田的存在显示出最大的影响，其次是土壤对林业的适宜性。同样，植树造林与当地植被的更替密切相关，助长了持续的森林砍伐，森林政策的变化增加了当地土地的扩张。
