Abstract Atriplex includes species with multiple purposes such as biomass for energy production, for bioremediation of soils contaminated with metals, or soil conservation. In Chile, 29 Atriplex species have been recorded, of which 21 are native. However, there are limited studies on these species. Agro-climatic zonation allows for determining the land aptitude Atriplex species cultivation according to the climatic conditions where their growth has been documented. The objective of this study was to establish the agro-climatic regions suitable for growing Atriplex in northern Chile by carrying out agro-climatic zonation. Our results revealed that an area of 4.89 million hectares is suitable for Atriplex growth, of which the Atacama region comprises the most (42.9%). Meanwhile, the best conditions for Atriplex growth, i.e. where it is adapted without thermal and hydric restriction, were registered in Arica and Parinacota and Coquimbo regions (7135 hectares).

估计 Atriplex L. 土地适宜性的方法。 [Amaranthaceae Juss。(sl)] 在干旱和半干旱地区种植

摘要 Atriplex 包括具有多种用途的物种，例如用于能源生产的生物质、用于金属污染土壤的生物修复或土壤保护。在智利，已记录了 29 种 Atriplex 物种，其中 21 种是本地的。然而，对这些物种的研究有限。农业气候区划允许根据 Atriplex 物种生长记录的气候条件确定其土地适应性。本研究的目的是通过进行农业气候区划，在智利北部建立适合种植 Atriplex 的农业气候区。我们的结果显示，有 489 万公顷的面积适合 Atriplex 生长，其中阿塔卡马地区最多 (42.9%)。同时，Atriplex 生长的最佳条件，即
