随着城市化进程的加快，人类活动对城市不同生境土壤中的微生物产生了很多影响，但城市不同生境中的真菌组成和多样性仍不清楚。本研究主要收集了我国20个高度城市化的省市城市近郊农用地、医院绿地、污水处理厂绿地和动物园绿地的240份土壤样品，采用传统可培养技术，探究城市不同生境土壤可培养真菌的群落组成及多样性特征，基于FUNGuild解析不同生境的真菌生态功能群并对其进行解钾、解磷、固氮和降解角蛋白的功能注释分析。从240份土壤样品中共分离获得真菌9 779株，隶属于3门14纲44目101科250属582种。在门分类水平上，它们主要隶属于子囊菌门Ascomycota、担子菌门Basidiomycota和毛霉菌门Mucoromycota。不同土壤生境可培养真菌群落α多样性存在明显差异。污水处理厂绿地土壤真菌α多样性最高，其次为动物园绿地和医院绿地，农业用地土壤样本中的真菌群落α多样性最小。动物园和医院绿地的降解角蛋白真菌类群最丰富、多样性最高。本研究揭示了我国高度城市化地区不同生境绿地土壤可培养真菌的群落组成、多样性和功能群。这为未来城市土壤微生物资源的管理提供了关键信息。"/>template{display:none;}.mag-rich-xref-fn { cursor: pointer;}//长视频$(document).ready(function(){if($("#showLongArticleVideo") && $("#showLongArticleVideo").length && $("#showLongArticleVideo").length>0){mag_ajax_update({ele_id:'showLongArticleVideo',url:mag_currentQikanUrl() + "/CN/article/showLongArticleVideo.do?id="+$("#articleId").val()});}});//可视化图谱$(document).ready(function(){if($("#showArticle_knowledgeMap") && $("#showArticle_knowledgeMap").length && $("#showArticle_knowledgeMap").length>0){jQuery.getJSON("/Jwxb/CN/lexeme/existsCnctstInArticle.do?articleID="+$("#articleId").val(), null, function(json){if(json.result){$("#showArticle_knowledgeMap").show();}});}});$(document).ready(function(){var metaDataStr = $.trim($("#article_metaJson").val());if(metaDataStr!=''){eval("window.metaData="+metaDataStr);}if(window.metaData && (!window.metaData.authorNotesCommon_cn && !window.metaData.authorNotesCorresp_cn && window.metaData.authorNotes_cn)){window.metaData.authorNotesCommon_cn = window.metaData.authorNotes_cn;}if(window.metaData && (!window.metaData.authorNotesCommon_en && !window.metaData.authorNotesCorresp_en && window.metaData.authorNotes_en)){window.metaData.authorNotesCommon_en = window.metaData.authorNotes_en;}var _nlmdtdXml = $("#article_nlmdtdXml").val();var magDir = _nlmdtdXml.replace(/\/[^\/]+$/,'');window.metaData.magDir = magDir;new mag_vue({ el: '#metaVue', //dataUrl: mag_currentQikanUrl() + '/EN/article/getRichHtmlJson.do?articleId='+$("#articleId").val(), data:window.metaData, loading:true, doTextFun:function(text){ return doDataJsonText(text);
