通过对山西省长治市白马小流域的1个标准小区和4个植物措施小区近5 a(2006—2010年)的降雨和径流泥沙观测,研究太行山土石山区的降雨特征以及不同类型降雨对典型植物措施小区径流泥沙的影响。结果表明:(1)太行山土石山区侵蚀性降雨主要集中于5—8月份,7—8月份侵蚀性降雨次数占侵蚀性降雨总次数的54.55%,侵蚀性降雨量占侵蚀性降雨总量的61.19%,故该时期是防治水土流失的关键时期;(2)径流量R与降雨量P、最大30 min降雨强度I30、降雨量和最大30 min降雨强度的乘积PI30呈正相关且在0.01水平上显著;侵蚀产沙量E与最大30 min降雨强度I30、径流量R、降雨量和最大30 min降雨强度的乘积PI30之间呈正相关且在0.01水平上显著;(3)在不同类型降雨条件下,4种典型植物措施的减流效益在17.18%~91.86%之间,差异明显;在B类型降雨条件下各措施的减流效益最低,分别是乔木43.38%、灌木24.44%、人工种草26.59%、自然荒坡17.18%,在E类型降雨条件下各措施的减流效益最大,分别是乔木89.29%、灌木91.86%、人工种草75.56%、自然荒坡66.22%;(4)在不同类型降雨条件下,减沙效益:乔木林>灌木林>人工种草>自然荒坡;降雨量最大的A类型降雨和最大30 min降雨强度最大的B类型降雨对植物措施减沙效益影响显著。研究结果表明,在该地区不同类型降雨条件下4种植物措施的减流减沙效益明显,能够有效防治水土流失。
Rainfall characteristics and the effects of different types of rainfall on runoff and sediment of typical plant measures in rocky mountain areas of Taihang were studied based on the observation of rainfall
runoff and sediment of a standard runoff plots and four plant measures runoff plots nearly five years (2006—2010) in Baima small watershed Changzhi city
Shanxi Province. The results showed that: 1)Erosive rainfall mainly concentrated in May to August in rocky mountain areas of Taihang. The number of erosive rainfall accounted for 54.55% of the total number of erosive rainfall in July and August
the precipitation of erosive rainfall accounted for 61.19% of the total precipitation of erosive rainfall
so the period was the key to the prevention and control of soil and water loss; 2)Runoff (R) and precipitation (P)
maximum 30 min rainfall intensity (I30)
the product of precipitation and maximum 30 min rainfall intensity (PI30) had positive correlation and significant at the 0.01 level; Erosion (E) and maximum 30 min rainfall intensity (I30)
runoff (R)
the product of precipitation and maximum 30 min rainfall intensity (PI30) had positive correlation and significant at the 0.01 level. 3)Under the condition of different types of rainfall
the runoff reduction benefits of 4 kinds of typical plant measures between 17.18%~91.86%
difference was obvious; Under the condition of B type rainfall
the runoff reduction benefits of 4 kinds of typical plant measures was the lowest
arbor was 43.38%
shrubs was 24.44%
artificial grass was 26.59%
natural slope was 17.18%; Under the condition of E type rainfall
the runoff reduction benefits of 4 kinds of typical plant measures was the largest
arbor was 89.29%
shrubs was 91.86%
artificial grass was 75.56%
natural slope was 66.22%; 4)Under the condition of different types of rainfall
the sediment reduction benefits were: arbor>shrub>artificial grass>natural slope; The influence of the largest precipitation of A type rainfall and the biggest maximum 30 min rainfall intensity of B type rainfall on the sediment reduction benefits of plant measures was remarkable. In conclusion
under the condition of different types of rainfall
the runoff and sediment reduction benefits of 4 kinds of plant measures was obvious; Plant measures could effectively control soil and water loss in the region.
