Abstract
Ground-surface complicationsTimemonitoringbyremote sensinghasgreat Importance to understand heinterrelationshipsbetween human andnatural Phenomenaandoptimal decision. Landsat TMimages (years: 2001 and 2011) of Taftanpasturesin Khashcity, with225, 01hectares area, were Analyzedusingidrisisoftwareinthisstudy.Indexeswere builtinidrisisoftwarein the first Phase.Bands andindicesas the dependent variableandtheamount of cover vegetation In measured siteswereusedasindependent variables, at correlations reviews. Spss Softwareand t-testwas usedtodetermine thecorrelation.In this study, indicatorsthathad Thehighestcorrelation withvegetation wereidentifiedand appropriateindicatorsto Assesstrendswere determined, also.Index withthe highestcorrelationwas used Tomapcoverageusingclassification method.In the next PhaseusingsurveydmapstransfertoArcgisenvironment, standard coverage classeswere Prepared.The results showed that6of8used indicators, MSAVI, TSAVI, TSAVI, SAVA and ARVIhave the highestcorrelationwithcanopy cover ThatbetweenthemTSAVIandRVIindicatorsis the best indicator toassessingchanges. Non-significant correlationwas betweenNDVIandNDVI index.The result indicates Anegativecoverage trendin this period, approximately200, 000ha ofrangland; have Decrease inthe canopy level
