Abstract [Objective]To investigate and evaluate wild Tamarix chinensis resources in Delingha City at Qinghai Province. [Method]Wild T. chinensis resources in Delingha City at Qinghai Province were studied based on belt transect method， field measurement method，remote sensing investigation method， drone aerial photography， and so on. [Result]Wild T. chinensis area in Delingha City at Qinghai Province was 53 397.68 hm2，number of plants （number of clusters） was 8 752 167.Wild T. chinensis resources was mainly with 5%-10% & above 20% coverage， 91.11% of the areas， 93.53% of the plants.Wild T. chinensis resources area was mainly distributed in shrubby woodlands and grasslands，7170% of the areas in grasslands，66.68% of the plants in shrubby woodlands.Wild T. chinensis resource distribution area was mainly in scattered state， 47.65% of the areas， pant number distribution was dominated by associated state， 66.12% of the plants.Wild T. chinensis resource distribution inside the protected area and plant number was all above 63.00%.[Conclusion]Wild T. chinensis in Delingha City at Qinghai Province was mainly distributed in shrubby woodlands and grasslands， majority was within 5%～10% & above 20% coverage， most areas in grasslands， dominated by scattered state； most plants in shrubby woodlands， dominated by associated state.
