冬虫夏草是青藏高原的珍稀物种，具有较高的药用和经济价值，然而其资源的数量特征、空间分布格局及适宜度尚不清晰。本研究以青海省冬虫夏草资源生境条件为依据，以海拔、植被、土壤、气温和降水量作为主要指标，利用地理信息系统(geographic information system，GIS)的空间分析方法对青海省冬虫夏草资源适宜性及空间分布进行分析，并用野外实地采样进行验证。研究表明：玉树州的玉树市、杂多县、称多县、曲麻莱县；果洛州的玛沁县、达日县、甘德县等区域多处在适宜区；海北州的祁连县、刚察县，黄南州的泽库县、河南县、同仁县，玉树州的治多县、囊谦县，海南州的兴海县、同德县、贵南县及其他产冬虫夏草县的部分区域为较适宜区；西宁市的大通县，海东市的互助县和海西州的低海拔地区为不适宜区。整个青藏高原具有冬虫夏草分布面积占当地县域国土面积的76.2%。在青海省具有冬虫夏草分布的地区(市/州)中，玉树州和果洛州冬虫夏草分布的面积占当地县域国土面积的88.3%-99.6%，海北州、海东市、海南州、海西州、黄南州和西宁市冬虫夏草分布面积占当地县域国土面积的30.2%-96.5%。综合区划图能比较真实地反映青海省冬虫夏草资源的空间分布格局，区划结果与实地调查结果相符，表明利用空间分析方法进行冬虫夏草资源的适宜性分布区域的划分是可行的，该研究为合理开发和科学利用冬虫夏草野生资源提供理论依据。"/>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);
