梯田是全球范围内一系列农业景观的重要资本投资，通常会持续远远超出任何单一农业周期并持续许多人类世代。本文首先强调，虽然人口增长往往与梯田建设工作存在松散联系，但这种关联绝不是直接的。然后，我们认为，选择梯田景观的哪些部分是由一系列文化和环境优先事项驱动的，这些优先事项通过全球、本地和自相关建模的组合以及基于模拟的方法进行最有效的探索。结果表明，地表地质、地形坡度、先存阶地和先存人类居住模式都是重要的构造特征。我们还认为梯田是土壤保持的方法，对台面尺度侵蚀模型的不加批判的使用提出质疑，并认为地中海地区灾难性土壤流失的模式常常被夸大。然而，如果谨慎且相对地部署，侵蚀模型仍然可以用于探索梯田确实管理农业有利地区的局部土壤运动的方法，我们的结果表明，这些措施确实改善了该地区的很大一部分侵蚀。 (C) 2010 Elsevier B.V. 保留所有权利。
Terraces are important capital investments in a range of agricultural landscapes worldwide, typically enduring well beyond any single farming cycle and over many human generations. This paper begins by emphasising that, while human population growth may often be loosely linked to terrace construction efforts, the association is by no means a straightforward one. We then argue that the choice of which parts of the landscape to terrace is driven by a range of cultural and environmental priorities that are most usefully explored by a combination of global, local and auto-correlative modelling, as well as via simulation-based methods. The results demonstrate that surficial geology, terrain slope, preexisting terraces and pre-existing patterns of human habitation are all important structuring features. We also consider terraces as method for soil conservation, question the uncritical use of mesa-scale erosion models and argue that patterns of catastrophic soil loss are often overstated in Mediterranean contexts. However, erosion modelling can, if deployed cautiously and comparatively, nonetheless be used to explore ways in which terraces do indeed manage localised soil movement in agriculturally favoured parts of the landscape, with our results suggesting that a substantial proportion of the erosion in this regions is indeed ameliorated by such measures.
