摘要
采用新疆林业二类调查数据,对新疆梭梭林生态系统服务的物质量和价值量进行评估,结果表明:(1)新疆梭梭林每年提供的保育土壤,固碳释氧,增加营养物质,净化大气,防风固沙,生物多样性保护等生态系统服务总价值高达4839546.23万元。(2)新疆三大区域梭梭林生态服务价值从大到小依次为北疆、东疆和南疆。(3)各地、州和市梭梭林生态服务价值大小排序为塔城地区>昌吉州>阿勒泰地区>博州>克拉玛依市>哈密地区>乌鲁木齐市>巴州>吐鲁番地区>阿克苏地区>伊犁州>喀什地区。(4)防风固沙和生物多样性保护功能是新疆梭梭林生态系统主要的生态功能,二者产生的价值占总价值的86.02%。(5)新疆梭梭林以低盖度林分分布为主,其产生的生态系统服务价值远高于中、高盖度林分,为保持新疆梭梭林生态服务功能可持续发挥,需加强以低盖度为主的梭梭林林分的经营和管理。
The ecological service value of Haloxylon ammodendron forest was assessed with secondary forestry survey data in Xinjiang. The results are as follows. (1) The ecological service value of soil conservation, carbon fixation and oxygen release, increased nutrition, atmosphere purification, wind prevention and sand-fixation, biodiversity protection provided by the whole H. ammodendron forest was 48.395 billion yuan per year in Xinjiang. (2) For three regions in Xinjiang, the ecological service value of H. ammodendron forest decreased from northern, eastern to southern. (3) For 12 cities in Xinjiang, the order of ecological service value of H. ammodendron forest was Tachen 〉 Changji 〉 Altay 〉 Bozhou 〉 Karamay 〉 Hami 〉 Urumqi 〉 Bazhou 〉 Turpan 〉 Aksu 〉 Yili 〉 Kashgar. (4) The main ecological service value was sand-fixation and biodiversity conservation for H. ammodendron forest in Xinjiang, which accounted for 86.02% of the total service value. (5) The ecosystem service value of H. ammodendron was mainly provided by the lower coverage forest. It was necessary to strengthen their management to keep the sustainability of ecosystem service.
