Abstract

Soils provide essential ecosystem services for the existence of ecosystems and biodiversity. It is crucial to understand their quality through the evaluation of ecological processes. However, only some studies estimate the effectiveness of ecosystem restoration based on evaluating soil quality (SQ) indicators. This research evaluated the five most common land-use scenarios in Andean ecosystems within the Natural Reserve of the Civil Society (RNSC) “La Montaña Mágica” under natural forest, coffee plantation, badlands, and active and passive restoration. The main objective was to analyze the physical, chemical, and biological characteristics concerning land use, establish the baseline for SQ indicators in different land use activities, and determine the status of restoration systems for other land uses in the study site. ANOVA and Dunnett's test evaluated SQ parameters. In passive and active restoration, soil bulk density, porosity, and the number of individuals and families of macroinvertebrates were improved. The latter presented low pH and aluminum values but increased potassium compared to other soil uses. The restoration strategies favored changes in SQ indicators due to the contribution of organic carbon, a developed root system, and the recirculation of nutrients in the edaphic system. This study provided information on changes in SQ with soil usage as a practical tool to evaluate ecological restoration methods in natural areas of the eastern Colombian Andes.

土壤质量:哥伦比亚安第斯山脉自然保护区的恢复指标
摘要 土壤为生态系统和生物多样性的存在提供了重要的生态系统服务。通过评估生态过程来了解土壤质量至关重要。然而,只有一些研究根据土壤质量(SQ)指标评估生态系统恢复的有效性。这项研究评估了民间社会自然保护区(RNSC)"La Montaña Mágica "内安第斯生态系统在天然林、咖啡种植园、荒地以及主动和被动恢复情况下最常见的五种土地使用方案。主要目的是分析与土地利用有关的物理、化学和生物特征,建立不同土地利用活动的 SQ 指标基线,并确定研究地点其他土地利用的恢复系统状况。方差分析和邓尼特检验评估了土壤质量参数。在被动和主动修复中,土壤容重、孔隙度以及大型无脊椎动物的个体和家族数量都得到了改善。后者的 pH 值和铝值较低,但与其他用途的土壤相比,钾含量有所增加。由于有机碳的贡献、发达的根系以及营养物质在土壤系统中的再循环,恢复策略有利于土壤质量指标的变化。这项研究提供了土壤质量随土壤用途变化的信息,是评估哥伦比亚安第斯山脉东部自然区生态恢复方法的实用工具。

期刊介绍: Agroforestry Systems is an international scientific journal that publishes results of novel, high impact original research, critical reviews and short communications on any aspect of agroforestry. The journal particularly encourages contributions that demonstrate the role of agroforestry in providing commodity as well non-commodity benefits such as ecosystem services. Papers dealing with both biophysical and socioeconomic aspects are welcome. These include results of investigations of a fundamental or applied nature dealing with integrated systems involving trees and crops and/or livestock. Manuscripts that are purely descriptive in nature or confirmatory in nature of well-established findings, and with limited international scope are discouraged. To be acceptable for publication, the information presented must be relevant to a context wider than the specific location where the study was undertaken, and provide new insight or make a significant contribution to the agroforestry knowledge base
