Study on the ecosystem service function value of wet land and meadowland in Xinjiang ABI lakeside

This paper use ETM and GIS date of 2000 year, using ecosystem service evaluation parameter which Costanza advanced, estimate that the ecosystem service function value of wet land and meadowland in Xinjiang ABI lakeside is 8.76×10⁸ RMB/hm². The contribution rate in the total meadow ecosystem service function value of Sacsaoul desert, tamarix cone, salt marsh, salt meadow are 26.03%, 21.36%, 20.93%, 13.45%. The ecosystem service function value of wet land in ABI lakeside separately take up 4.89%, 0.48% of the total ecosystem service function value in whole basin and whole Xinjiang. It proved that ecosystem service function of wet land in lakeside is very important to ecological security in whole basin and whole Xinjiang. From now on meadow land resources should be highly protected in case of disturbing by human activities and domestic animals.
