| Abstract: | Studies on a 51 years old Castanopsis eyrei community in Wuyishan Mountains show that the standing had a storage of 1029.96kg·hm-2 Ca and 231.34kg·hm-2 Mg, 801.40kg·hm-2 Ca and 159.68kg·hm-2 Mg in aboveground part, and 228.56kg·hm-2 Ca and 71.66kg·hm-2 Mg in underground part.The annual uptake was 63.17kg·hm-2 Ca and 18.68kg·hm-2 Mg, annual retention was 31.77kg·hm-2 Ca and 11.41kg·hm-2 Mg, and annual return was 31.40 kg·hm-2 Ca and 7.27kg·hm-2 Mg.The enrichment ratios of Ca and Mg were 1.66 and 2.14, respectively. |
