Evaluation of Forest Ecosystem Services in Xinjiang Production and Construction Corps
Based on the latest investigation data of the forest resources in Xinjiang Production and Construction Corps (XPCC),the author assessed the ecosystem service values of each type of forest quantitatively in each division of XPCC according to national norms and existing research literatures.1) The total values of forest ecosystem service functions of XPCC were 82.070 58 billion yuan per year,30.53％ of which were from water conservation,44.20％ from erosion control and 25.27％ from carbon fixation and oxygen release,accumulation of nutrients,air purification,protection effect of forest,biodiversity protection and recreation and eco-tourism.2)The values of ecosystem service provided by different forest types from high to low were in the order of shrubbery,populus,poplar,economic forests of arbors,other broad-leaved forest,spruce,open forest,elm forest,birch forest,cypress and larch.3) While nearly 70％ of ecosystem services values in mountainous regions were contributed by water conservation and biodiversity protection,more than 80％ of ecosystem service values in plain areas came from water conservation,erosion control and carbon fixation and oxygen release.The results of the assessment have a positive impact on profound consideration,adjustment and optimization of traditional model of economic growth.
