Surface interpolation of environmental factors as tool for evaluation of the occurrence of high methane and nitrous oxide fluxes

Lengerer Andreas; Kazda Marian

摘要

Abstract > Greenhouse gas (GHG) emissions from wetlands typically exhibit extended low‐flux phases accompanied by distinct high‐flux events. Prediction and explanation of flux occurrence is hindered by various interactions of the underlying environmental predictors. Here, a novel approach is described to gain insight in patterns of environmental factors, which lead to elevated emissions. Natural neighbor interpolation was utilized to construct flux intensity maps based on two environmental predictors, the ground water level and soil temperature. Further, the effect of inhomogeneous data density was considered by filtering estimates for sufficient information content. The practical application was exemplified by CH <sub>4</sub> and N <sub>2</sub> O flux field data of three years from two fen sites in southwest Germany. This approach considered factor interactions as well as the fluxes occurring as rare events. The application can be useful for the delineation of driving conditions for high‐flux events as well as for wetland management practice. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml：lang =“en”> <title type =“main”>抽象</ title> >温室气体（GHG）来自湿地的排放通常伴随着不同的高通量事件伴随着延长的低通量阶段。通过底层环境预测因子的各种相互作用阻碍了通量发生的预测和解释。这里，描述了一种新的方法来增强环境因素模式的洞察力，这导致升高的排放。利用自然邻插值来构建基于两个环境预测因子，地下水位和土壤温度的助焊强度图。此外，通过过滤足够的信息内容的估计来考虑不均匀数据密度的效果。实际应用是由CH <sub> 4 </ sub>和n <sub> 2 </ sub> o通量现场数据从西南西南西南部的两个芬特网站。这种方法被认为是因子相互作用以及作为罕见事件而发生的助熔剂。该应用可用于划分高通量事件的驾驶条件以及湿地管理实践。 </ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-35667/'>《Journal of plant nutrition and soil science》</a> <b style="margin: 0 2px;">|</b><span>2018年第1期</span><b style="margin: 0 2px;">|</b><span>共10页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Lengerer Andreas&option=202" target="_blank" rel="nofollow">Lengerer Andreas;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Kazda Marian&option=202" target="_blank" rel="nofollow">Kazda Marian;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Institute for Systematic Botany and EcologyUniversity of UlmAlbert-Einstein-Allee 11 89081 Ulm Germany;</p> <p>Institute for Systematic Botany and EcologyUniversity of UlmAlbert-Einstein-Allee 11 89081 Ulm Germany;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/212.html" title="农业基础科学">农业基础科学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=flux&option=203" rel="nofollow">flux;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=greenhouse gas emission&option=203" rel="nofollow">greenhouse gas emission;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=natural neighbor interpolation&option=203" rel="nofollow">natural neighbor interpolation;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=response surface&option=203" rel="nofollow">response surface;</a> </p> <div class="translation"> 机译：助焊剂;温室气体排放;天然邻插值;响应面;
