Based on the analysis of 604 tree ring series and 157 stumps, it was found that the intensities of disturbance in both plot Ⅰ and plot Ⅱ generally were high, for example, it reached 31.4%/10a in 1950′s in plot Ⅰ and 18.1%/10a in 1980′s in plot Ⅱ, which indicated local frequent activities of selective or illegal cutting. The percent rate between section area of tree stumps and all section area of trees and stumps which was assumed to be the actual disturbance intensity of recent 30a were also compared with the reconstructed percent rate from tree ring analysis. It was found that the reconstructed rate was close to the actual rate in plot Ⅰ with a normal distribution of tree age structure, but it was larger than the actual rate in plot Ⅱ with non\|normal distribution of tree age structure.</em></p><p class='subject'><strong>关 键 词：</strong><a href='/zk/search.aspx?key=K%3d%5b%e9%9d%92%e6%b5%b7%e9%ba%a6%e7%a7%80%e6%9e%97%e5%9c%ba%5d' title='青海麦秀林场'>青海麦秀林场</a> <a href='/subject/article.aspx?id=9222263' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e6%ac%a1%e7%94%9f%e6%9e%97%5d' title='次生林'>次生林</a> <a href='/zk/search.aspx?key=K%3d%5b%e6%a0%91%e8%bd%ae%e5%88%86%e6%9e%90%5d' title='树轮分析'>树轮分析</a> <a href='/zk/search.aspx?key=K%3d%5b%e5%b9%b2%e6%89%b0%e9%87%8d%e5%bb%ba%5d' title='干扰重建'>干扰重建</a> <a href='/zk/search.aspx?key=K%3d%5b%e5%b9%b2%e6%89%b0%e5%bc%ba%e5%ba%a6%5d' title='干扰强度'>干扰强度</a> <a href='/subject/article.aspx?id=3514952' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e7%b4%ab%e6%9e%9c%e4%ba%91%e6%9d%89%5d' title='紫果云杉'>紫果云杉</a> </p><p class='class'><strong>分 类 号：</strong><a href='/zk/search.aspx?key=C%3dS718.5' title='S718.5'>S718.5</a>[<a href = '/domain/article.aspx?id=542' >农业科学—林学</a>] <a href='/zk/search.aspx?key=C%3dS791.18' title='S791.18'>S791.18</a></p> </div> <div id="content_wzxg" name="wzxg" class="article-graph"> <object width="695" height="250" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" id="FlashID"> <param value="../flash/relation.swf" name="movie"> <param value="high" name="quality"> <param value="opaque" name="wmode"> <param value="6.0.65.0" name="swfversion"> <param value="dataUrl=/ajax/articlerelativegraph.ashx?id=6661299" name="flashVars"> <embed width="695" height="250" src="../flash/relation.swf" type="application/x-shockwave-flash" quality="high" wmode="opaque" flashvars="dataUrl=/ajax/articlerelativegraph.ashx?id=6661299"> </embed> </object> </div> <div class="article-relate-list"> <div class="relate-list"> <p id="ckwx_br"> </p> <h2 name="ckwx" id="ckwx">参考文献：</h2> <div id="listckwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="2jckwx_br"> </p> <h2 name="2jckwx" id="2jckwx">二级参考文献：</h2> <div id="list2jckwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="ohwx_br"> </p> <h2 name="ohwx" id="ohwx">耦合文献：</h2> <div id="listohwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="yzwx_br"> </p> <h2 name="yzwx" id="yzwx">引证文献：</h2> <div id="listyzwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="2jyzwx_br"> </p> <h2 name="2jyzwx" id="2jyzwx">二级引证文献：</h2> <div id="list2jyzwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="tbywx_br"> </p> <h2 name="tbywx" id="tbywx">同被引文献：</h2> <div id="listtbywx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="xgqklw_br"> </p> <h2 name="xgqklw" id="xgqklw">相关期刊文献：</h2> <div id="listxgqklw"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> </div> </div> <div class="article-about"> <div class="about-box"> <h5 class="name">相关的主题<tt><a class="hide" href="#"></a></tt></h5> <div class="about-list"> </div> </div> <div class="about-box"> <h5 class="name">相关的作者对象<tt><a class="" href="#"></a></tt></h5> <div class="about-list" style="display: none;"> </div> </div> <div class="about-box"> <h5 class="name">相关的机构对象<tt><a class="" href="#"></a></tt></h5> <div class="about-list" style="display: none;"> </div> </div> </div> </div> </div> <script type="text/javascript" src="/scripts/articlerelation.min.js"></script> <script type="text/javascript" src="/scripts/articlerightrelation.min.js"></script> <script type="text/javascript" src="/scripts/articledown.min.js"></script> <div class="layer-box download" id="downloadlayer" style="display: none"> <div class="close"> <a onclick="closedown()" href="javascript:void(0)"> <img src="/images/layer-close.png" width="21" height="21" alt="" /> </a> </div> <h5 class="layer-title">下载全文</h5> <div id="downloadinfo"></div> </div> <div class="layer-box download" id="downloadlayer2" style="display:none;min-height:100px;width:500px;"> <p> <img src="/images/loading2.gif" width="64" height="64"> <span style="font-size:20px;vertical-align:middle;padding-bottom:50px;">正在链接到云南高校图书馆文献保障联盟下载...</span> </p> </div> <script id="bdshare_js" data="type=tools&uid=0" type="text/javascript"></script> <script type="text/javascript"> $(function () { var rd = GetQueryString("rd");
