中亞費(fèi)爾干納盆地灌溉氣候效應(yīng)的數(shù)值模擬研究

的數(shù)值模擬研究溉改善作物生長食產(chǎn)量是這一地區(qū)的關(guān)鍵問題。本文通過數(shù)值模擬分析，研究該地區(qū)氣候的影響，結(jié)果表明灌溉改變了該地區(qū)的水熱條件和，對(duì)局地氣溫和降水量均產(chǎn)生了較大的影響。此外，灌溉也對(duì)土地利用和生態(tài)環(huán)境造成了一定程度的影響。文章旨在為中亞費(fèi)爾干納盆地；灌溉；數(shù)值模擬；氣候影響；生態(tài)環(huán)境兩部分氣候和生態(tài)環(huán)境有很大差異。北部屬于干旱荒漠氣候和，而南部則屬于溫帶干燥氣候。由于缺乏降水，該地區(qū)的農(nóng)業(yè)限制。但是這里擁有豐富的水資源，通過灌溉的方法可以改善農(nóng)業(yè)生產(chǎn)條件。然而，同時(shí)也需要考慮灌溉對(duì)氣候和生態(tài)的影，電腦數(shù)值模擬成為了一種有效的手段，來研究灌溉對(duì)該地區(qū)善農(nóng)業(yè)生產(chǎn)和水資源利用的重要手段。中亞費(fèi)爾干納盆地程度不高，主要是由于長期的政治、經(jīng)濟(jì)以及地域因素導(dǎo)致的有不到20%的農(nóng)田完成了灌溉。這的影響氣溫和降水是種植季節(jié)農(nóng)業(yè)生產(chǎn)的主要環(huán)境因素。灌溉改變了該地區(qū)的土壤濕度和水分循環(huán)，使得該地區(qū)的氣候條件發(fā)生了變化。果表明，灌溉對(duì)氣溫和降水都產(chǎn)生了一定的影響。一方面，灌溉面，灌溉還會(huì)增加植被覆蓋，促進(jìn)水循環(huán)，也能對(duì)地區(qū)的降水產(chǎn)。在中亞費(fèi)爾干納盆地，由于地形和氣候條件復(fù)雜，灌溉對(duì)降水境的影響對(duì)該地區(qū)生態(tài)環(huán)境也有一定的影響。在該地區(qū)，灌溉面積較小，但產(chǎn)生的影響是不容忽視的。灌溉增加了土壤濕度，也加劇了土壤侵蝕、水土流失和水平面污染，這都會(huì)對(duì)地區(qū)的生態(tài)環(huán)境造成不同程度的影響。值模擬分析，研究了灌溉對(duì)中亞費(fèi)爾干納盆地氣候和生地氣溫和降水量均產(chǎn)生了較大的影響。同時(shí)，也對(duì)該地區(qū)的土地利ovFKuchkarovYetalApplyingstochasticoptimizationinacomplexriverbasinmanagement:thecaseofFerganaValley[J].JournalofWaterandLandDevelopment,2018,36(1):41-52.費(fèi)爾干納盆地的水資源開發(fā)與保護(hù)[J].水文,2016(5):2-7.亞地區(qū)灌溉農(nóng)業(yè)現(xiàn)狀及變化特點(diǎn)[J].涉外經(jīng)濟(jì)與貿(mào)易大學(xué)學(xué)報(bào),2010(3):112-116.TitleNumericalsimulationofirrigationclimaticeffectsinFerganaAbstract:aBasininCentralAsiaisanaridandsemiaridareaHowtoimprovecropgrowthandincreasefoodproductionthroughirrigationisakeyissueinthisregionInthispaper,throughnumericalsimulationanalysistheimpactofirrigationontheclimateofthisregionhasbeenstudiedTheresultsshowthatirrigationhaschangedthewaterandheatconditionsandsoilhumidityofthisregionandhashadasignificantimpactonlocaltemperatureandprecipitationInaddition,irrigationhasalsohadacertaindegreeofimpactonlanduseandecologicalenvironmentintheregionThepurposeofthispaperistorovideusefulinformationfortheagriculturaldevelopmentandecologicalenvironmentimprovementinFerganaBasin.rganaBasinIrrigationNumericalsimulationClimateimpact,Ecologicalenvironment.ninCentralAsiaisanimportantagriculturalproductionareaandriverbasin.However,thereisgreatdifferenceinclimaticandecologicalenvironmentbetweenitsnorthandsouth.Thenorthbelongstoariddesertclimateandgrasslandclimate,whilethesouthbelongstotemperateandaridclimate.Lackofprecipitationoftenlimitsagriculturalproductioninthisregion.However,ithasabundantwaterresourcesandirrigationisoneoftheeffectivewaystoimproveagriculturalproductionconditions.Butatthesametime,theimpactofirrigationonclimateandecologyalsoneedstobeconsidered.Therefore,computernumericalsimulationhasbecomeaneffectivemeanstostudytheimpactofirrigationontheclimateandecologicalenvironmentofthisregion.erganaBasingationisanimportantmeanstoimproveagriculturalproductionandwaterresourcesutilizationHoweverthedevelopmentofirrigationinFerganaBasinisnothigh,mainlyduetotheaginganddamageofirrigationfacilitiescausedbylongtermpoliticaleconomicandgeographicalfactorsInthisregionlessthan20%offarmlandhascompletedirrigationThisalsomeansthattheagriculturalproductioncapacityinthisregionhasnotbeenfullyutilized.actofirrigationontemperatureandprecipitationinthisTemperatureandprecipitationarethemainenvironmentalfactorsforagriculturalproductioninthisregion.Irrigationhaschangedsoilhumidityandwatercirculationofthisregion,sothatclimateconditionsofthisregionhavechanged.Simulationresultsshowthatirrigationhashadanimpactontemperatureandprecipitation.Ontheonehand,irrigationhelpstoimprovesoilhumidity,increasesoilevaporationandinfiltrationandaffectlocaltemperature.Ontheotherhand,irrigationalsoincreasesvegetationcoverpromoteswatercirculation,andcanalsoaffectprecipitationintheregion.InFerganaBasin,duetothecomplextopographyandclimaticconditions,theimpactofirrigationonprecipitationisnotfullyconsistent.pactofirrigationonecologicalenvironmentinthisregionigationalsohasacertainimpactontheecologicalenvironmentinthisregionInthisregion,althoughtheareaofirrigationissmall,theimpactisnotnegligibleIrrigationincreasessoilhumidity,butalsoexacerbatessoilerosion,landdegradationandwaterpollution,allofwhichcanhaveadifferentdegreeofimpactontheecologicalenvironmentInadditionirrigationhasalsochangedlanduseinthisregion,helpingtopromotediversifiedagriculturaldevelopment.onInthispaperthroughnumericalsimulationanalysis,theimpactofirrigationontheclimateandecologicalenvironmentofFerganaBasininCentralAsiahasbeenstudied.Thestudyshowsthatirrigationhaschangedthewaterandheatconditionsandsoilhumidityofthisregion,andhashadasignificantimpactonlocaltemperatureandprecipitation.Atthesametime,irrigationhasalsohadacertaindegreeofimpactonlanduseandecologicalenvironmentintheregion.Inordertofullyutilizetheadvantagesbroughtbyirrigation,aseriesofmeasuresshouldbetakentocoordinatethedevelopmentandutilizationofwaterresourcesandtheprotectionandimprovementofecologicalenvironment.ovFKuchkarovYetalApplyingstochasticoptimizationinacomplexriverbasinmanagement:thecaseofFerganaValley[J].JournalofWaterandLandDevel
