Zoige　plateau　has　been　affected　by　the　global　climate　change,　especially　the　effects　of　some　unreasonable　human　activities.　The　ecological　restoration　and　carbon　fixation　function　of　the　desertified　grassland　are　widely　concerned　at　home　and　abroad.　The　plant　samples　and　soil　samples　were　collected　from　treatment　area,and　field　investigation　and　experiment　analysis　of　ecosystem　restoration　process　of　the　treatment　area　were　carried　out.　Taking　spatial　structure　instead　of　times　series,　a　lot　of　method　was　used　to　analyze　the　change　of　carbon　content,　carbon　storage　and　carbon　density.　The　results　show　that　during　the　5　years　of　management　and　protection:　(1)　Carbon　content　of　the　samples　changes　between　36.　67　-44.41　g　kg-1,　carbon　density　changes　between　8.　87　-57.　62　kg　m-2;　carbon　storage　changes　between(　10.　61　-36.56)　x　104　t　hm-2　and　with　the　increase　of　treatment　years,　carbon　density　and　carbon　storage　show　a　gradually　increasing　trend;　(2)　Plant　biomass　and　carbon　content　has　a　good　linear　relationship,　the　accumulation　of　plant　biomass　is　beneficial　to　increasement　of　carbon　storage.　(3)　Physico-　chemical　properties　of　soil　are　improved　and　carbon　fixation　ability　is　recovered　with　the　ecological　restoration.　Founded　on　correlation　analysis,　soil　organic　carbon,　soil　organic　matter　and　texture　show　a　significant　positive　correlation　with　water　content,　and　a　negtive　correlation　with,　pH　value;　(4)　By　the　analysis　of　meteorological　data,　the　temperature　of　Zoige　area　in　recent　years　is　higher　than　its　average　temperature,　the　status　accelerates　the　carbon　decomposition,　and　is　unfavorable　to　the　grassland　carbon　sequestration　and　the　adjustment　of　carbon　balance.　Based　on　the　above　results,　the　research　of　carbon　fixation　provides　basic　data　for　the　treatment　of　grassland　desertification　under　the　background　of　global　climate　change,　and　will　also　provide　a　realistic　basis　for　the　further　improvement　of　Zoige　desertified　grassland　management　and　the　study　of　ecological　restoration.
