植被生态需水理论及计算研究进展摘要生態需水研究是近年来国内外广泛关注的热点，涉及生态学、水文学、环境科学等多个学科。植被生态需水研究对于指导区域植被生态恢复与生态建设具有重要意义，是生态需水的重要研究内容。本文系统回顾了国内外植被生态需水的研究进展，较为全面地介绍了植被生态需水的概念和内涵，总结并介绍了植被生态需水的各种计算方法。对各类植被生态需水计算方法的基本思想、优缺点、差异及其适用范围做了重点介绍，并分析了国内外植被生态需水的研究进展及发展趋势。通过对过去植被生态需水研究的总结与分析认为，国外研究的侧重点为土壤、大气和植被之间的生态水文过程以及维系自然生态系统平衡，我国研究的侧重点为水资源供需矛盾突出以及生态环境相对脆弱和问题严重的干旱、半干旱和季节性干旱的湿润区，但由于起步晚，在这方面的研究尚不成熟，同时，植被生态需水的计算没有一个具体的标准和完整的理论体系。关键词植被；生态需水；计算方法；发展趋势中图分类号X171.1文献标识码A文章编号1007-5739（2020）02-0179-04ResearchProgressonTheoryandCalculationofVegetationEcologicalWaterRequirementWEIHua（LandandWaterResourcesResearchCenteroftheMiddleReachesofYangtzeRiver，SchoolofResourcesEnvironmentScienceandEngineering，HubeiUniversityofScienceandTechnology，XianningHubei437100）AbstractThestudyonecologicalwaterrequirementisahottopicconcernedathomeandabroadinrecentyears，involvingmultiplesubjectssuchasecology，hydrology，environmentalscience.Researchofvegetationecologicalwaterrequirementisoneoftheimportantresearchcontentsofecologicalwater此资料由网络收集而来，如有侵权请告知上传者立即删除。资料共分享，我们负责传递知识。requirement，whichisalsoofgreatsignificancetoguideregionalvegetationecologicalrestorationandconstruction.Thispapersystematicallyreviewedtheresearchprogressofvegetationecologicalwaterrequirementathomeandabroad，comprehensivelyintroducedtheconceptandconnotationofvegetationecologicalwaterrequirement，summarizedandintroducedthevariouscalculationmethodsofvegetationecologicalwaterrequirement，highlightedthebasicidea，advantagesanddisadvantages，differencesandtheapplicationscopeofvegetationecologicalwaterrequirementforallkindsofcalculationmethods.Alsotheresearchprogressanddevelopmenttrendofvegetationecologicalwaterrequirementathomeandabroadwereanalyzed.Bysummarizingandanalyzingthepaststudiesofvegetationecologicalwaterrequirement，theforeignresearchonvegetationecologicalwaterrequirementfocusedonsoil，theeco-hydrologicalprocessbetweenatmosphereandvegetation，maintainthenaturalecosystembalance，whiledomesticresearchwasmoreconcentratedontheprominentcontradictionbetweensupplyanddemandofwaterresources，andrelativelyfragileecologicalenvironmentintheseveredroughtseasonalarid，semi-aridandsemi-humid.However，duetostartinglate，theresearchinthisaspectwasnotverymature，atthesametime，therewasnotaspecificstandardandcompletetheoreticalsysteminthecalculationofvegetationecologicalwaterrequirement.此资料由网络收集而来，如有侵权请告知上传者立即删除。资料共分享，我们负责传递知识。
