摘要:
通过测定官司河流域紫色土区柏木麻栎混交林(Cupressus funebris,Quercus acutissima)、柏木纯林、方竹林(Chimonobambusa quadrangularis)、农地四种植被类型土壤理化性质、土壤孔隙状况及水文特征,揭示紫色土区不同植被类型土壤理化性质和水文效应空间分布特征。结果表明:(1)土壤有机碳含量表现为:柏木麻栎混交林>方竹林>柏木纯林>农地。柏木麻栎混交林土壤有机碳(18.04 g /kg)、全氮(1.51 g /kg)、全磷(1.49 g/kg)、全钾(53.1 g/kg)、速效氮(81.69 mg /kg)、速效磷(2.14 mg /kg)积累作用最好。(2)不同植被类型土壤容重均值表现为农地>柏木纯林>柏木麻栎混交林>方竹林,随土层加深4种植被类型容重变化规律不同,其中农地增加幅度最大,为9.34%。(3)0-100 cm土层自然含水量、毛管持水量、最大持水量、含蓄降水量均表现为柏木麻栎混交林最高,田间持水量表现为农地最高。随着土层加深,不同植被类型水文效应规律变化差异较大。综上表明:不同植被类型不同土层深度土壤理化性质和水文效应特征差异显著,柏木麻栎混交林较柏木纯林更适宜在研究区推广种植,方竹林对该区土壤状况适应性较好,结果可为川中丘陵区紫色土人工林经营管理、生态环境恢复及水源涵养功能评价提供理论依据。
Abstract:
This paper reveals that the differences of Soil Physical and Chemical Properties in the 0-40 cm soil layer, and porosity, hydrological effect characteristic in the 0-100 cm soil layer, and the variation at spatial scales of 4 vegetation types ( Cupressus funebris - Quercus acutissima, Cupressus funebris, Chimonobambusa quadrangularis, farmland) in central sichuan hill region. By measuring soil organic carbon content, bulk density, porosity, water storage in different vegetation types and different depths. The results showed that: (1) Average organic carbon content of 4 vegetation types in 0-20 soil layer was as follows Cupressus funebris - Quercus acutissima > Chimonobambusa quadrangularis > Cupressus funebris >farmland. The organic carbon content of Cupressus funebris-Quercus acutissima Mixed forests soil was 18.04 g/kg, total nitrogen content was 1.51 g/kg, total phosphorus content was 1.49 g/kg, total potassium was 53.1 g/kg, available nitrogen was 81.69 mg/kg, available phosphorus was 2.14 mg/kg, the accumulation of these nutrients was best. (2) the mean soil bulk density of different forest types was shown as farmland > Cupressus funebris > Cupressus – Quercus > Chimonobambusa quadrangularis, which varied with the deepening of soil layer. Among them, the largest increase was farmland ,which was 9.34%. (3) Soil Cupressus – Quercus mixed forest which the natural water content, the capillary water holding capacity, the maximum water holding capacity and the implied precipitation in the 0-100 cm soil layer are the highest,and farmland ?s field water holding capacity is the highest .As the soil layer deepens, different types of hydrological effects regular vary greatly. Cupressus – Quercus mixed forest is more suitable for planting in the research area than pure cypress wood forest, and the bamboo forest has good adaptability to the soil condition in this area. The results can provide a theoretical basis for the management, ecological environment restoration and water conservation function evaluation of the artificial forest under different stand in the purple soil area of the hilly region of central Sichuan.
