科尔沁沙地典型固沙植物水分传输过程研究的中期报告
摘要
本研究旨在探究科尔沁沙地典型固沙植物蒙古花青的水分传输过程。通过野外实验和室内模拟实验，测量了不同环境条件下植物的水分含量、蒸腾速率和气孔导度等指标，并分析了这些指标之间的关系。
实验结果表明，蒙古花青的水分含量和蒸腾速率受到环境温度和湿度的显著影响。在温度较高、湿度较低的条件下，植物的蒸腾速率增加，导致水分含量降低。而在温度较低、湿度较高的条件下，植物的蒸腾速率减少，水分含量增加。此外，气孔导度与蒸腾速率呈正相关，表明气孔开放程度与蒸腾速率有重要关系。
综合上述结果，可以得出，蒙古花青的水分传输过程与环境因素密切相关，在不同的环境条件下，植物的水分含量、蒸腾速率和气孔导度会发生变化。

Abstract
ThisstudyaimstoinvestigatethewatertransportprocessofMongoliaQing,atypicalsand-fixingplantintheKorqinSandyLand.Throughfieldexperimentsandindoorsimulationexperiments,variousindicatorssuchaswatercontent,transpirationrate,andstomatalconductanceofplantsunderdifferentenvironmentalconditionsweremeasured,andtherelationshipsbetweentheseindicatorswereanalyzed.
TheexperimentalresultsshowedthatthewatercontentandtranspirationrateofMongoliaQingweresignificantlyaffectedbyenvironmentaltemperatureandhumidity.Underhighertemperatureandlowerhumidityconditions,thetranspirationrateoftheplantincreased,leadingtoadecreaseinwatercontent.Conversely,underlowertemperatureandhigherhumidityconditions,thetranspirationrateoftheplantdecreased,resultinginanincreaseinwatercontent.Inaddition,stomatalconductancewaspositivelycorrelatedwithtranspirationrate,indicatinganimportantrelationshipbetweenstomatalopeningandtranspirationrate.
Basedontheaboveresults,itcanbeconcludedthatthewatertransportprocessofMongoliaQingiscloselyrelatedtoenvironmentalfactors,andthewatercontent,transpirationrate,andstomatalconductanceoftheplantwillchangeunderdifferentenvironmentalconditions.
