退耕还林土壤动物群落结构及其演变的研究综述与应用前景

Review and Application Prospect of Soil Animal Community Structure and Evolution in Returning Cropland to Forest

土壤动物群落结构及其演变特征能反映生态系统的退化、恢复或重建过程,也能为评价人类利用土地及其管理方式的可持续性提供科学依据。长期以来,有关黄土丘陵沟壑区退耕还林土壤动物群落变化及其演变机理的系统研究鲜有报道。通过综述退耕还林区土壤动物和土壤因子及地上植被之间的互动效应和演变机理,分析退耕还林植被恢复对土壤动物的影响以及土壤动物对植被演替的响应特征,为黄土丘陵沟壑区土壤退化与生态恢复研究提供更广阔的应用前景。建议今后从土壤动物的生态过程与环境效应方面开展研究,可丰富和完善黄土高原退耕还林区土壤退化及生态恢复的研究方法,以推进黄河流域生态保护和高质量发展。

Soil animal community structure and its evolution characteristics can not only reflect the process of eco⁃system degradation,restoration or reconstruction,but also provide a scientific basis for evaluating the sustainability of human land use and its management.For a long time,there are few systematic studies on the change and evolution mechanism of soil animal community in returning farmland to forest in loess hilly and gully region.By summarizing the interaction and evolution mechanism between soil animals,soil factors and aboveground vegetation in the area of returning farmland to forest,the effects of vegetation restoration on soil animals and the response characteristics of soil animals to vegetation succession are analyzed.It provides a broader application prospect for the study of soil deg⁃radation and ecological restoration in loess hilly and gully region.It is suggested that the future research on the eco⁃logical process and environmental effects of soil animals can enrich and improve the research methods of soil degra⁃dation and ecological restoration in the area of returning farmland to forest on the Loess Plateau,so as to promote ec⁃ological protection and high-quality development in the Yellow River basin.
