The Lake Pátzcuaro region has recently been a focus of attention of various scholars working in the field of cultural studies. These works have highlighted the role of Lake Pátzcuaro in creating a national culture and identity during the postrevolutionary period in México (1920–1940). However, the cultural production of nature has not been subject to the same attention. Taking a cultural and historical geography approach, the paper considers the production of Lake Pátzcuaro's ‘naturecultures’ during the postrevolutionary period in México. This is how discourses about culture and identity shaped nature and vice versa. The emphasis is on what I call scientific cultures of nature, referring to ideas and practices around nature that made use of scientific claims. The goal is to understand the role of these practices in shaping Lake Pátzcuaro as a meaningful discursive assemblage, and the relationship between this process and nation-state building. I do this by examining the discourses surrounding the establishment of environmental protection schemes in Lake Pátzcuaro, comprising the creation of a ‘forest hydrological reserve’ and fishing regulations, and the introduction of species to protect native fish and improve fisheries. I argue that these actions took part in broader efforts to create México and the Mexican, contributing to the naturalization of narratives about the nation.

帕茨夸罗湖地区最近成为了从事文化研究领域的各种学者关注的焦点。这些作品突出了 Pátzcuaro 湖在墨西哥革命后时期（1920-1940 年）在创造民族文化和身份方面的作用。然而，自然的文化生产却没有受到同样的重视。本文采用文化和历史地理学的方法，考察了墨西哥革命后时期帕茨夸罗湖的“自然文化”的产生。这就是关于文化和身份的话语如何塑造自然，反之亦然。重点是我所说的自然科学文化，指的是利用科学主张的围绕自然的思想和实践。目标是了解这些实践在将帕茨夸罗湖塑造为一个有意义的话语集合中的作用，以及这一过程与民族国家建设之间的关系。我通过研究围绕 Pátzcuaro 湖建立环境保护计划的论述来做到这一点，包括建立“森林水文保护区”和渔业法规，以及引入物种以保护本地鱼类和改善渔业。我认为，这些行动参与了创造墨西哥和墨西哥人的更广泛努力，有助于国家叙事的自然化。包括创建“森林水文保护区”和渔业法规，以及引入物种以保护本地鱼类和改善渔业。我认为，这些行动参与了创造墨西哥和墨西哥人的更广泛努力，有助于国家叙事的自然化。包括创建“森林水文保护区”和渔业法规，以及引入物种以保护本地鱼类和改善渔业。我认为，这些行动参与了创造墨西哥和墨西哥人的更广泛努力，有助于国家叙事的自然化。
