荒漠灌丛土壤动物分布及其生态功能

在干旱、半干旱荒漠生态系统中,灌丛作为一种重要的植被类型,其独特的形态和生理适应特性能够有效促进退化生态系统结构与功能的恢复。土壤动物是荒漠生态系统中不可或缺的重要组成部分,对促进灌丛"肥岛"演变具有重要的生态作用,有利于灌丛生态功能的发挥及退化生态系统的恢复。近年来,国内外学者对荒漠灌丛微生境土壤动物的研究逐步深入,取得大量的研究成果。在此基础上,首先综述荒漠灌丛微生境土壤动物群落分布和生态功能,总结灌丛与土壤动物分布间作用关系的数学模型,针对荒漠灌丛土壤动物研究中存在的问题提出了未来可能的研究方向和建议。

Distribution and ecological function of soil faunal within shrub microhabitats in desert

Shrub is an important vegetation type in arid and semi-arid desert ecosystems. Its unique morphological and physiological adaptation characteristics can effectively promote the restoration of the structure and function of degraded desert ecosystems. Soil faunal is an indispensable and important part of desert steppe ecosystems, which plays an important ecological role in promoting the evolution of "fertile island" of shrubs, and is conducive to the play of the ecological function of shrubs and the restoration of degraded ecosystems. In recent years, domestic and foreign scholars have gradually deepened the research on soil fauna in desert shrub microhabitats and obtained a great achievement. On this basis, the distribution and ecological functions of soil faunal community in desert shrub microhabitats were summarized firstly. Then the mathematical model of the interaction between shrubs and soil faunal distribution was summarized. Finally, the possible future research directions and suggestions were put forward in view of the existing problems in the study of soil faunal within shrub microhabitats in desert.
