摘要
与直接减排相比,土壤固碳是一种风险更大的减缓气候变化的长期战略,因为它在缩小碳排放差距方面发挥着主要作用。红树林生态系统是分布在红海沿岸,在埃及西海岸延伸500公里的天然湿地。从Abu Monquar岛(北纬27°12′58”,东经33°52′34”)开始,在赫尔格达市北部附近调查了5个采样点。本研究探讨了红树林类型(Avicennia marina)原始种群对土壤固碳的影响。得到的土壤表面(0 ~ 30 cm)实测土壤容重平均值显示,阿布蒙夸尔岛(Abu Monquar Island)和萨法加(Safaga)土壤容重最小,分别为1.31±0.02 g cm -3和1.53±0.05 g cm -3。而在El Gouna 1、2和Hurghada, SBD值从1.63到1.75 g cm -3不等。对照场地(无植物滩涂)土壤干容重为1.75±0.05g cm -3。另一方面,以Abu Monquar岛的碳酸钙含量最高,为168。Gouna1、Gouna2、赫尔格达、萨法加和对照的碳酸钙含量分别为26.60 gKg -1、69.30 gKg -1、58.50 gKg -1、91.90 gKg -1和26.90 gKg -1。土壤表层(0 ~ 90cm)实测土壤有机碳库(SOCP)均值显示,赫尔格达岛最低,为8.81±0.12 Mgha -1,阿布蒙夸尔岛最高,为59.75±0.15 Mgha -1。而El Gouna 1、2和Safaga的SOCP值分别为14.48、12.86和39.98 Mgha -1。对照点(无植物海滩)的SOCP为6.62±0.25 Mgha -1。因此,红树林生态系统在固存土壤有机碳和减少大气co2方面具有很大的潜力。
INFLUENCE OF MANGROVE ECOSYSTEM ON SOIL CARBON SEQUESTRATION AND GLOBAL WARMING AT THE WESTERN STRAND OF THE RED SEA, EGYPT
: Soil carbon sequestration is a riskier long-term strategy for climate mitigation than direct emissions reduction as it plays a main role in closing carbon emission gaps. Mangrove ecosystem is a natural wetland that allocated at Red Sea and extended for 500 km at the Egyptian western coast. Five sampling sites were investigated at the north near to the city of Hurghada beginning from the Abu Monquar Island (27° 12′ 58′′N, 33° 52′ 34′′E). This work investigates the impact of the original population of Mangrove type (Avicennia marina ) on the soil carbon sequestration. Obtained results of the mean values of measured soil bulk density (SBD) at the soil surface (0-30 cm) were revealed that the lowest values of the SBD was at Abu Monquar Island with 1.31± 0.02, g cm -3 and at Safaga with 1.53 ± 0.05 g cm -3 . While at El Gouna 1, 2 and at Hurghada the SBD values varied from 1.63 to 1.75 g cm -3 . In addition, the soil dry bulk density at the control site (beach without plants) was 1.75± 0.05g cm -3 . On the other hand, the highest values of the Calcium carbonate were obtained Abu Monquar island with 168. 20 gKg -1 , while the Calcium carbonate values were 26.60 gKg -1 , 69.30 gKg -1 , 58.50 gKg -1 , 91.90 gKg -1 and 26.90 gKg -1 for Gouna1, Gouna2, Hurghada, Safaga, and the control, respectively. The mean values of measured soil organic carbon pool (SOCP) at the soil surface (0-90cm) revealed that the lowest values of the SOCP was at Hurghada with 8.81± 0.12 Mgha -1 and the highest values at Abu Monquar island with 59.75 ± 0.15 Mgha -1 . While at El Gouna 1, 2 and at Safaga the SOCP values were 14.48, 12.86, and 39.98 Mgha -1 , respectively. In addition, the SOCP at the control site (beach without plants) was 6.62± 0.25 Mgha -1 . Thus the Mangrove ecosystem has a great potential to sequestrate the soil organic carbon and reduce the atmospheric CO 2 .
