Abstract

Purpose

Brazilian territory is divided into six biomes (Amazon, Atlantic Forest, Cerrado, Caatinga, Pantanal, and Pampa) that represent important global biodiversity hotspots. Research into soil science in these environments has increased in recent years, but a quantitative and qualitative mapping of research into the soils of Brazilian biomes has never been carried out. In this study, research on soil science in the Brazilian biomes were analyzed to map the evolution, scientific collaboration, current status, research trends and impact over the last 50 years (1972–2022).

Methods

The database was obtained from the Core Collection of Web of Science. The data was quantitatively analyzed through descriptive statistics and linear regression using Microsoft Excel, and qualitatively using the bibliometric software VOSviewer.

Results

A total of 11,231 papers were obtained. The results indicated a significant increase in soil science research across all biomes (polynomial growth), with greater emphasis for research in the Cerrado (R² = 0.9361), Amazon (R² = 0.9170) and Atlantic Forest (R² = 0.9104) biomes. Soil science research in the Amazon accounted for 47.0% of the research conducted in all Brazilian biomes. While in the Amazon (38.8%), Atlantic Forest (34.8%), and Pantanal (36.7%), most of the research was related to environmental sciences and ecology, in the Cerrado (47.4%), Caatinga (58.2%), and Pampa biome (48.9%), research in the field of agriculture was more significant. For all biomes, except for the Caatinga (a dry climate biome), a significant participation of international researchers and institutions was evident in the overall publications. This demonstrates a lower global interest in soil science research in the Brazilian dry ecosystem.

Conclusion

Soil science research in the Brazilian biomes is disproportionate, with greater interest in the soils of the larger forest biomes and less interest in the dry and flooded areas. The results of this study can be useful for the development of public policies, research and scientific collaboration aimed at soil conservation in Brazilian terrestrial biomes.

巴西陆地生物群落的土壤科学研究：对演变、合作、当前主题和影响的回顾

目的巴西领土被划分为六个生物群落（亚马逊、大西洋森林、塞拉多、卡廷加、潘塔纳尔和潘帕），是全球生物多样性的重要热点地区。近年来，对这些环境中土壤科学的研究不断增加，但对巴西生物群落土壤研究的定量和定性调查却从未进行过。本研究对巴西生物群落的土壤科学研究进行了分析，以绘制过去 50 年（1972-2022 年）的演变、科学合作、现状、研究趋势和影响图。通过使用 Microsoft Excel 进行描述性统计和线性回归对数据进行了定量分析，并使用文献计量软件 VOSviewer 对数据进行了定性分析。结果表明，所有生物群落的土壤科学研究都有显著增长（多项式增长），其中塞拉多（R2 = 0.9361）、亚马逊（R2 = 0.9170）和大西洋森林（R2 = 0.9104）生物群落的研究更为突出。亚马逊地区的土壤科学研究占巴西所有生物群落研究的 47.0%。在亚马逊生物群落（38.8%）、大西洋森林生物群落（34.8%）和潘塔纳尔生物群落（36.7%），大部分研究与环境科学和生态学有关，而在塞拉多生物群落（47.4%）、卡廷加生物群落（58.2%）和潘帕生物群落（48.9%），农业领域的研究更为重要。在所有生物群落中，除卡廷加（气候干燥的生物群落）外，国际研究人员和机构在整个出版物中的参与程度明显较高。这表明全球对巴西干旱生态系统土壤科学研究的兴趣较低。结论：巴西生物群落的土壤科学研究比例失调，对较大森林生物群落土壤的兴趣较大，而对干旱和洪涝地区的兴趣较小。这项研究的结果有助于制定公共政策、开展研究和科学合作，以保护巴西陆地生物群落的土壤。

期刊介绍： The Journal of Soils and Sediments (JSS) is devoted to soils and sediments; it deals with contaminated, intact and disturbed soils and sediments. JSS explores both the common aspects and the differences between these two environmental compartments. Inter-linkages at the catchment scale and with the Earth’s system (inter-compartment) are an important topic in JSS. The range of research coverage includes the effects of disturbances and contamination; research, strategies and technologies for prediction, prevention, and protection; identification and characterization; treatment, remediation and reuse; risk assessment and management; creation and implementation of quality standards; international regulation and legislation.
