摘要

本研究调查了伊朗三个不同生态区农林业系统(AGSs)的多样性和稳定性:半干旱的Arasbaran、半湿润的Zagros和湿润的hycanian地区。该研究旨在了解气候如何影响这些系统中的物种丰富度和多样性。从129个农场收集数据,在那里测量了物种鉴定和各种定量指标,如树的直径和高度。计算了Taxa_S、Shannon_H和Equitability_J等生物多样性指数,并利用参数模型分析了物种分布。结果表明,3个地区的物种丰富度和多样性存在显著差异。湿润区多样性最高,有10科22种,半干旱区多样性最低。湿润地区的Shannon指数和Taxa_S指数也显著高于其他两个地区,表明湿润气候支持的物种范围更广。相反,半干旱地区的平均树木体积最高,可能是由于某些物种更适应恶劣气候的优势。研究还发现,半干旱和半湿润地区分别对应于几何和断棒模式,表明不同程度的群落稳定性。研究结果表明,半湿润地区的AGSs比半干旱地区的AGSs更稳定,这可能是由于更有利的气候条件。本研究强调了考虑区域气候因素对农业生态系统开发和管理的重要性,以优化生物多样性保护和农业生产力。

Climatic influence on agroforestry systems: comparative analysis of species diversity and stability across semi-arid, semi-humid, and humid regions in Iran

This study investigates the diversity and stability of agroforestry systems (AGSs) across three distinct ecological regions in Iran: the semi-arid Arasbaran, the semi-humid Zagros, and the humid Hyrcanian regions. The research aims to understand how climate impacts species richness and diversity within these systems. Data was collected from 129 farms, where species identification and various quantitative metrics, such as tree diameter and height, were measured. Biodiversity indices including Taxa_S, Shannon_H, and Equitability_J were calculated, and the species distribution was analyzed using parametric models. The results indicate significant differences in species richness and diversity across the three regions. The humid region exhibited the highest diversity, with 22 species from 10 families, whereas the semi-arid region showed the lowest diversity. The Shannon and Taxa_S indices were also significantly higher in the humid region compared to the other two regions, suggesting that the humid climate supports a wider range of species. Conversely, the semi-arid region had the highest average tree volume, possibly due to the dominance of certain species better adapted to the harsh climate. The study also found that the semi-arid and semi-humid regions corresponded to geometric and broken stick models, respectively, indicating different levels of community stability. The findings suggest that AGSs in semi-humid regions are more stable than those in semi-arid regions, likely due to more favorable climatic conditions. This research highlights the importance of considering regional climatic factors in the development and management of AGSs to optimize biodiversity conservation and agricultural productivity.

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
