Soil organic carbon (SOC) content and density (SOCD) were studied under six land use patterns of Natural forest, Schima superba plantation, Coniferous forest, Bamboo forest, Orchard, and Abandoned land in the Dongjiang River valley of Guandong province, China. The results showed that surface soil (0~25 cm) organic carbon content and soil organic carbon density had significant difference (P -1) > Schima superba planted forest (21.1±0.79 g•kg-1) > Bamboo (20.9±0.53 g•kg-1) > Coniferous forest (15.65±0.93 g•kg-1) > Orchard (15.22±0.61 g•kg-1) > Abandoned land (8.69±0.38 g•kg-1), and Natural forest (67.16±2.31 kg•m-2) > Bamboo (60.08±1.53 kg•m-2) > Schima superba plantation (52.8±1.86 kg•m-2) > Coniferous forest (47.17±2.66 kg•m-2) > Orchard (43.03±1.56 kg•m-2) > Abandoned land (31.48±1.2 kg•m-2), respectively. Natural forest was the highest in both soil organic carbon content and soil organic carbon density, and Abandoned land the lowest. The findings suggested that a close-to-nature way of afforestation and forest management played an important role in increasing forest carbon sinks.

Grey Relational

This paper investigates the relations between soil organic carbon (SOC) and other physicochemical indices in low hills of Chifeng, Inner Mongolia, and thus to help with soil modification in low hills there. Grey relational analysis and stepwise regression analysis were used to uncover the relations of SOC with total N (TN), pH, available P (AP), available K (AK), and microbial biomass carbon (MBC) under eight land use patterns in a typical small watershed in Chifeng. The eight land uses were Prunus sibirica land, Caragana microphylla land, Populus simonii land, Ulmus pumila land, natural grassland, Pinus Tableulaeformis [Formula: see text] P. sibirica mixed land, secondary forest of natural bush land, and agricultural land. The average SOC contents in the 0–100[Formula: see text]cm layer in the above eight land use patterns are 7.72, 5.32, 7.40, 6.11, 3.14, 10.26, 17.51 and 5.34[Formula: see text]g/kg, respectively, indicating significant differences. The relation coefficients of SOC with TN, pH, MBC, AK, and AP are 0.70, 0.66, 0.63, 0.57 and 0.55, respectively, under all land use patterns. SOC contents are significantly different among these land use patterns, and the relation coefficients of SOC with other physicochemical indices rank in the order as: [Formula: see text]. The optimum regression equation of SOC ([Formula: see text] with TN ([Formula: see text] and pH ([Formula: see text] was built: [Formula: see text], ([Formula: see text]).

Cyclobalanopsis Glauca

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).

Abstract. Effects of forest conversion to poplar plantation on soil organic carbon (SOC) stocks were investigated by sampling paired plots in an alluvial area of the Ticino river in Northern Italy. According to land registers and historical aerial photographs, the two sites were part of a larger area of a 200 years-old natural forest that was partly converted to poplar plantation in 1973. The soil sampling of three layers down to a depth of 100 cm was performed at 90 and 70 points in the natural forest (NF) and in the nearby poplar plantation (PP), respectively. The substitution of the natural forest with the poplar plantation strongly modified soil C stock down to a depth of 55 cm, although the management practices at PP were not intensive. By evaluation of equivalent soil masses, the comparison of C stocks (organic layer included) between the different land uses showed a decrease in SOC of 5.7 kg m−2 after 37 years of poplar cultivation, corresponding to more than 1/3 of the initial organic carbon content. The land use change from NF to PP not only affected the stock but also the vertical distribution of SOC: ploughing led to the transfer of SOC from soil surface into the deeper layers resulting in a more uniform allocation of organic carbon in the ploughed layer and disappearance of the SOC stratification observed in the forest.
