摘要

目的

为探究电场修复技术（ET）在不同气候条件下对石漠化区土壤微生态的调控作用。

方法

以重度石漠化区土壤为研究对象，通过室内模拟石漠化土壤生境及干旱和降雨过程，探究持续运行的20 V电场处理对土壤理化性质及细菌群落结构与功能的影响。

结果

与对照（CK）相比，电场处理在干季与雨季显著增加土壤有机碳、碱解氮和速效钾的含量，抑制有效磷含量在干季流失，但电场处理的存在显著降低土壤含水量和pH。电场处理下干季与雨季土壤细菌群落的丰富度和多样性指数均显著降低，且干季与雨季细菌属水平群落结构组成差异显著，门水平群落组成不变。在干季，电场显著富集变形菌门、鞘氨醇单胞菌属、黄色土源菌属和西索恩氏菌属；在雨季，显著富集放线菌门、蓝细菌门，慢生根瘤菌属、中生根瘤菌

属、德莱氏菌属、

Burkholderia⁃Caballeronia⁃Paraburkholderia

、嗜酸细小链孢菌属、拟无枝酸菌属、

Mucilaginibacter

和杆状菌属。在雨季，电场处理显著提高土壤细菌群落中光合作用（叶绿体）及固氮作用等功能的相对丰度。RDA分析表明，土壤碱解氮、有效磷和含水量是驱动细菌群落演变的主要环境因子。

结论

电场处理可通过调节关键土壤因子，优化细菌群落结构并增强其生态功能，从而促进石漠化土壤养分循环与系统恢复，为石漠化地区的生态治理提供理论依据。

Abstract

Objective

This study aims to investigate the regulatory effects of electric field treatment （ET） on soil microecology in rocky desertification areas under different climatic conditions.

Methods

Using severely rocky desertified soil as the research subject， a laboratory simulation of the rocky desertification soil habitat along with drought and rainfall processes was conducted. The effects of a continuously operating 20 V electric field treatment on soil physicochemical properties and the structure and functions of bacterial communities were investigated.

Results

Compared with the control （CK）， the electric field treatment significantly increased the contents of soil organic carbon， alkaline hydrolyzable nitrogen， and available potassium during both the dry and rainy seasons， and inhibited the loss of available phosphorus during the dry season. However， the electric field treatment significantly decreased soil water content and pH. Under the electric field treatment， the richness and diversity indices of the soil bacterial communities were significantly reduced in both the dry and rainy seasons. The community structure composition at the genus level differed significantly between the dry and rainy seasons， while the composition at the phylum level remained unchanged. During the dry season， the electric field significantly enriched Proteobacteria，

Sphingomonas

，

Flavisolibacter

， and

Chthoniobacter

. During the rainy season， it significantly enriched Actinobacte-riota， Cyanobacteria，

Bradyrhizobium

，

Mesorhizobium

，

Dyella

，

Burkholderia

Caballeronia

Paraburkholderia

，

Catenulispora

，

Amycolatopsis

，

Mucilaginibacter

， and

Edaphobacter

. During the rainy season， electric field treatment significantly increased the relative abundance of functions such as photosynthesis （chloroplast） and nitrogen fixation in the soil bacterial community. Redundancy analysis （RDA） indicated that soil alkaline hydrolyzable nitrogen， available phosphorus， and water content were the main environmental factors driving the evolution of the bacterial community.

Conclusion

Electric field treatment can optimize bacterial community structure and enhance its ecological functions by regulating key soil factors， thereby promoting nutrient cycling and system restoration in rocky desertified soil and providing a theoretical basis for ecological management in rocky desertification areas.
