- 摘要:
- 为了明确延河流域2003—2014年土壤保持量的时空动态变化特征及其约束条件,基于合成孔径雷达(Interferometric Synthetic Aperture Radar,INSAR)获取的高分辨率数字高程模型(Digital Elevation Model,DEM),结合SWAT(Soil and Water Assessment Tool)水文模型模拟流域逐月土壤保持量,从时空变化的角度展开分析,并引入流域水土保持措施及植被覆盖措施数据,以此揭示水土保持治理对流域土壤保持服务的影响。并在此基础上通过叠加分析揭示了地形因子对土壤保持的影响。结果表明:(1)SWAT模型在进行径流、泥沙模拟时,率定期和验证期的模拟结果均达到模型要求。(2)2003—2014期间,延河流域年均土壤保持量为1 002.02万t,以土壤低保持量为主。土壤保持量的时空动态特征表现为时间变化主要受降水量影响,总体上呈增加趋势; 空间变化主要受地形影响,具体表现为下游最大,上游次之,中游最低。其中2003年和2014年的空间分布特征表明,多年来实施的水土保持措施以及植被覆盖措施产生了明显的生态效益。(3)土壤保持量受坡度、高程、坡向的影响规律明显,具体表现为:随坡度、高程的增大土壤保持量呈先增大后减小的趋势; 对坡向而言,土壤保持量表现为半阳坡>阴坡>阳坡>半阴坡>平地。该研究可为延河流域水土治理提供一定的科学依据。
- Abstract:
- To clarify the spatiotemporal dynamic characteristics and constraints of soil conservation in Yanhe River Basin from 2003 to 2014, the high-resolution Digital Elevation Model(DEM)obtained by Interferometric Synthetic Aperture Radar(InSAR)was used to simulate the monthly soil conservation in the watershed by combining with SWAT(Soil and Water Assessment Tool)hydrological Model. From the perspective of spatial and temporal changes, the data of soil and water conservation measures and vegetation cover measures were introduced to reveal the impact of soil and water conservation treatment on soil conservation services in the basin. On this basis, the impact of topographic factors on soil conservation was revealed by superposition analysis. The results showed that:(1)when the SWAT model was used to simulate runoff and sediment, the simulation results of the calibration and validation period met the requirements of the model;(2)from 2003 to 2014, the average annual soil retention in the Yanhe watershed was 1.002 02×107 t, which was dominated by low soil retention; the temporal and spatial dynamic characteristics of soil conservation were shown as follows: the temporal change was mainly affected by precipitation, which showed the increasing trend on the whole; the spatial variation was mainly affected by the terrain, which was the largest in the downstream, followed by the upstream, and the lowest in the middle; the spatial distribution characteristics in 2003 and 2014 indicated that soil and water conservation and vegetation cover measures implemented over the years had produced obvious ecological benefits.(2)The soil conservation was influenced by slope, elevation, and slope direction, which was shown as follows: with the increase of slope and elevation, the soil conservation increased at first and then decreased; for aspect, the soil conservation volume decreased in the order: half sunny slope>shady slope>sunny slope>half shady slope>flat. This study can provide the scientific basis for soil and water control in the Yanhe River Basin.
