- 摘要:
- 为了明确7Be示踪黄土高原水蚀风蚀交错带不同类型土壤侵蚀(风蚀和水蚀)的可行性,以该区域的典型土壤(粉壤土、粉黏土、沙壤土和风沙土)为对象,通过分析7Be的土壤剖面分布特征、张弛质量深度及其季节变化,明确了在该区域不同类型土壤中的分布特征。结果表明:7Be在土壤剖面的分布受土壤类型和季节变化的影响。对不同类型的土壤,无论风季还是雨季,土壤中7Be的分布特征均与土壤黏粒含量密切相关,反映7Be在土壤剖面分布特征的关键参数土壤张弛质量深度h0与黏粒含量呈明显线性负相关关系(R2>0.87)。此外,4种土壤的h0均表现为风季大于雨季。由于该区域明显的风水侵蚀季节分异,为运用7Be示踪技术区分风力和水力的影响提供了可能。然而,对黏粒含量较低的风沙土,其侵蚀速率较大且侵蚀特征明显异于其他3种土壤,尤为突出的是水蚀过程中常表现出明显的重力侵蚀特征。可见,7Be可用于示踪粉壤土、粉黏土和沙壤土的风水交错侵蚀,而在风沙土中的适用性较差。
- Abstract:
- In order to clarify the feasibility of beryllium-7 to soil erosion study for different types of soils in the wind-water erosion crisscross region of the Loess Plateau, we analyzed seasonal variation of beryllium-7 distribution in soil profile, and the relaxation mass depth of four typical local soils(silty clay, sand, sandy loam and soil loam. Results show that beryllium-7 distribution in soil profile is affected by both soil type and seasonal variation, and is closely related with soil clay content regardless of variation of windy and rainy seasons. The soil relaxation mass depth as one of the key factors for beryllium-7 distribution in soil profile is negatively linearly correlated with the clay content(R2>0.87). Moreover, the soil mass relaxation depth is greater in dry season compared to rainy season for all studied soil types, which results in feasibility of beryllium-7 measurements for soil wind and water erosion study in this multiple agents affecting region supporting by local obvious separate of dry and rainy season. However, higher erosion rate and characteristics of sandy soil with the high sand fraction are significantly disparate from those of the other 3 types of soils, particularly. gravity erosion characteristics of sandy soil obviously presents in water erosion process. Therefore, beryllium-7 measurement is suitable for tracing wind and water erosion of all three soil types, and is hardly suitable for tracing wind and water erosion of sandy soil.
