Moso Bamboo Forest

Abstract Native species are generally thought not to encroach on adjacent natural forest without human intervention. However, the phenomenon that native moso bamboo may encroach on surrounding natural forests by itself occurred in China. To certificate this encroaching process, we employed the transition front approach to monitor the native moso bamboo population dynamics in native Chinese fir and evergreen broadleaved forest bordering moso bamboo forest in Tianmu Mountain Nature Reserve during the period between 2005 and 2014. The results showed that the bamboo front moved toward the Chinese fir/evergreen broadleaved stand with the new bamboo produced yearly. Moso bamboo encroached at a rate of 1.28 m yr−1 in Chinese fir forest and 1.04 m yr−1 in evergreen broadleaved forest, and produced 533/437 new culms hm−2 yr−1 in the encroaching natural Chinese fir/evergreen broadleaved forest. Moso bamboo coverage was increasing while adjacent natural forest area decreasing continuously. These results indicate that native moso bamboo was encroaching adjacent natural forest gradually without human intervention. It should be considered to try to create a management regime that humans could selectively remove culms to decrease encroachment.

Three typical substropical evergreen broad-leaved forests (Castanopsis eyrei, Schima superba and Cyclobalanopsis glauca) in Wuyi Mountain National Nature Reserve of Jiangxi Province were selected to investigate its carbon sequestration capacity. The biomass and soil bulk density of sample investigation were get by setting sample investigation, field quadrat sampling, indoor sample making, experimental analysis testing, data statistics and analysis. The organic carbon content of vegetation layer (arbor layer, shrub layer and herbaceous layer, litter layer) and soil layer (0-10cm, 10-20cm, 20-30cm, 30-50cm and 50-100cm) were also get. The carbon density and carbon storage of subtropical evergreen broad-leaved forests vegetation and soil were estimated which including Castanopsis eyrei, Schima superba and Cyclobalanopsis glauca. The investigation results had shown that: The average organic carbon content of each vegetation layer in the investigation plot (400 m2) of Wuyi Mountain National Nature Reserve was arbor layer (54.07%)> shrub layer (52.8%)> herbaceous layer (47.5%), in which the average organic carbon content of the three subtropical evergreen broad-leaved forests in the arbor layer was close 52.97% to 54.87% and the total average content was 54.07%. The average carbon density of the forest vegetation layer was 178.3587t/hm2, the average carbon density of the vegetation layer was arbor layer (176.0273t/hm2)> shrub layer (1.3043t/hm2)> litter layer (0.8144t/hm2)> herbaceous layer (0.2127t/hm2); the average carbon density of each forest species was Castanopsis eyrei (213.5141t/hm2)> Schima superba (168.9069t/hm2)> Cyclobalanopsis glauca (152.6551t/hm2). Investigation sample of subtropical evergreen broad-leaved forest (400 m) in Wuyi Mountain National Nature Reserve, Jiangxi Province2 The average soil bulk density of each soil layer cm 0-100 g/cm was 0.868-1.816 g/cm3 both soil organic carbon content and soil carbon density decreased with the increase of soil depth. The average organic carbon content of each soil layer was between 3.75% and 12.48%, and the average soil carbon density was between 62.85t/hm2 and 146.14t/hm2. The average total carbon density of the soil in the investigated sample plots was 754.77t/hm2, of which the average soil carbon density in investigation sample plots in Castanopsis eyrei, Schima superba and Cyclobalanopsis glauca was 911.49t/hm2, 762.56t/hm2 and 543.22t/hm2 respectively. The average carbon storage of the investigation sample plot (400m2) in Jiangxi Wuyi Mountain National Nature Reserve were Castanopsis eyrei forest (45.0002t) >Cyclobalanopsis glauca forest (36.6087t) > Schima superba forest (28.4850t), the average soil carbon storage(30.1908t) was 4.23 times the average carbon storage(7.1314t).
