Abstract

 The carbon and nitrogen storage and distribution pattern of 10 a plantation of Taxodium ‘Zhongshanshan 118’ and soil (soil layer of 0-45 cm) were investigated in Dianchi of Yunnan Province. The results show that the contents of carbon and nitrogen in leaf, branch, and stem of T. ‘Zhongshanshan 118’ plantation are 439-520 and 3.34-5.22 g·kg-1, those in litter are 510 and 1.16 g·kg-1, and those in soil layer of 0-15, 15-30, and 30-45 cm are 4.76-8.78 and 0.28-0.61 g·kg-1, respectively. The carbon and nitrogen storage in stem of T. ‘Zhongshanshan 118’ plantation are relatively high, accounting for 60.9% and 57.1% of that of arbor layer (including leaf, branch, and stem), respectively. The carbon and nitrogen storage in soil layer of 0-45 cm are 41.24 and 1.73 t·hm-2, respectively, which exhibits an obvious surface enrichment. It is suggested that T. ‘Zhongshanshan 118’ has a strong carbon sequestration capacity, and has a great application potential in the forest ecosystem of Dianchi region.
