That forest carbon sink can alleviate the global warming is a hot research issue at present in the world.However,researches on the forest and fruit industry in Xijiang mainly focused on the economic values instead of the carbon sink values.In this paper,based on the data of the practical measurement in sampling plots and the data obtained from the statistic annual report of forest and fruit industry of Xinjiang in 2014,the function of carbon sink of seven main non-timber forest was calculated,and the benefits of the function were estimated according to the carbon tax law and market economy value method.The results were reported as follows.1) The amount of economic forest ecosystem carbon sink in Xinjiang was 14.49*10~5 t·a~(-1),per unit area in solid carbon was 1.90 t·hm~(-2)·a~(-1),stand in the total value of carbon sink was 2.10*10~9 yuan·a~(-1).2) In view of area and the growth period,the physical quantity of carbon sink and value quantity were in the orders of southern Xinjiang>northern Xinjiang>eastern Xinjiang,Initial laying period>full fruiting period>the prenatal period>decline period.3) In terms of tree species,the physical quantity and value quantity were in the order of apricot>walnut>pear>other trees>apple>jujube>almond.
