Title:ResearchonEcologicalSecurityEvaluationofLandinAltayRegionBasedonMulti-sourceData
Abstract:
Withtheincreasingglobalconcernforenvironmentalprotection,theevaluationofecologicalsecurityinvariousregionshasgainedsignificantattention.Inthisstudy,wefocusedontheAltayregion,aimingtoprovideacomprehensiveevaluationoftheecologicalsecurityofitslandthroughtheintegrationofmulti-sourcedata.
Introduction:
TheAltayregion,locatedinthenorthwestpartofChina,encompassesavastareaofdiverseecosystems,includinggrasslands,forests,wetlands,anddesertregions.Theseecosystemsprovidevariousecologicalservices,includingcarbonsequestration,waterfiltration,biodiversityconservation,andsoilstabilization.However,humanactivitiessuchasurbanization,agriculturalexpansion,andindustrializationhaveimposedincreasingpressuresontheregion'sland,leadingtopotentialecologicalrisks.
Methods:
Thisresearchadoptsamulti-sourcedataintegrationapproachtoevaluatetheecologicalsecurityoflandintheAltayregion.Thesourcesofdataincluderemotesensingimages,ecologicalmonitoringdata,socio-economicdata,andfieldsurveys.
1.LandUse/LandCoverClassification:
Remotesensingimagesareprocessedandclassifiedusingmachinelearningalgorithmstodeterminethelanduse/landcovertypesintheAltayregion.Thisallowsfortheidentificationandmappingofvariouslandcovercategoriessuchasforests,grasslands,croplands,andurbanareas.
2.EcologicalIndicators:
Variousindicators,suchasvegetationcover,soilerosion,waterquality,andbiodiversity,arecalculatedbasedonremotesensingandecologicalmonitoringdata.Theseindicatorsserveasquantitativemeasuresforevaluatingtheecologicalsecurityofdifferentlandcovertypes.
3.Socio-economicFactors:
Socio-economicfactors,suchaspopulationdensity,GDPpercapita,andindustrialdevelopmentintensity,areincorporatedtoanalyzetheinteractionsbetweenhumanactivitiesandecologicalsecurity.ThesefactorsprovideinsightsintothepotentialdriversofecologicalinsecurityintheAltayregion.
ResultsandDiscussion:
Basedontheanalysisofthemulti-sourcedata,theec
