- 摘要:
- 为分析白洋淀流域降雨侵蚀力的时空分布特征,利用白洋淀流域及周边64个气象站点2003—2018年的日雨量资料,采用日雨量模型、线性逐步回归、倾向率、Mann-Kendall突变检验以及克里金插值等方法进行了研究。结果表明:(1)白洋淀流域年均降雨侵蚀力为2 284.54(MJ·mm)/(hm2·h),西南阜平县和东北霞云岭降雨侵蚀力较大,在东南—西北方向上呈先增后降趋势。(2)气象站点降雨侵蚀力与经纬度、海拔的关系为:降雨侵蚀力=-0.115×纬度+0.414×经度-0.235×海拔,降雨侵蚀力与纬度、海拔呈负相关,与经度呈正相关。(3)降雨侵蚀力年内分布中,夏季较大,平均1 826.75(MJ·mm)/(hm2·h),冬季较小,平均1.77(MJ·mm)/(hm2·h); 降雨侵蚀力年际分布中,2011—2014年较大,平均2 584.82(MJ·mm)/(hm2·h); 2003—2006年较小,平均2 053.79(MJ·mm)/(hm2·h)。(4)降雨侵蚀力时间变化中,春季和夏季降雨侵蚀力倾向率分别为49.81(MJ·mm)/(hm2·h)和162.84(MJ·mm)/(hm2·h),秋季和冬季分别为-89.47(MJ·mm)/(hm2·h)和-0.07(MJ·mm)/(hm2·h),多年平均24.54(MJ·mm)/(hm2·h),整体上降雨侵蚀力呈逐年增加趋势,但这种趋势不显著。研究表明,白洋淀流域降雨侵蚀力呈夏季高、冬季低的季节性变化,整体上逐年增加,西南—东北方向的海拔起伏带和山前平原区降雨侵蚀力较大,因此,加强流域内重点区域、重要时间节点降雨侵蚀力的监测工作是开展水土流失防治工作的必要保障。
- Abstract:
- To analyze the temporal and spatial distribution characteristics of rainfall erosivity in Baiyangdian Basin. Using the daily rainfall data of 64 meteorological stations in and around Baiyangdian Basin from 2003 to 2018, the study is carried out by using daily rainfall model, linear stepwise regression, tendency rate, Mann-Kendall mutation test and Kriging interpolation. The results show that:(1)average annual rainfall erosivity of Baiyangdian Basin is 2 284.54(MJ·mm)/(hm2·h); rainfall erosivity of Fuping County in southwest China and Xiayunling Mountain in northeast China is larger, which increases at first and then decreases from southeast to northwest;(2)relationship between rainfall erosivity of meteorological stations and longitude, latitude and altitude as follows: rainfall erosivity = -0.115 × latitude + 0.414 × longitude -0.235 × altitude; rainfall erosivity is negatively correlated with latitude and altitude, and positively correlated with longitude;(3)the annual distribution of rainfall erosivity, it is larger in summer with an average of 1 826.75(MJ·mm)/(hm2·h)and smaller in winter with an average of 1.77(MJ·mm)/(hm2·h); the interannual distribution of rainfall erosivity, it is larger from 2011 to 2014, averaging 2 584.82(MJ·mm)/(hm2·h), and smaller from 2003 to 2006, averaging 2 053.79(MJ·mm)/(hm2·h);(4)the temporal variation of rainfall erosivity, tendency rates of rainfall erosivity are 49.81(MJ·mm)/(hm2·h)and 162.84(MJ·mm)/(hm2·h)in spring and summer, -89.47(MJ·mm)/(hm2·h)and -0.07(MJ·mm)/(hm2·h)in autumn and winter, respectively, with annual average of 24.54(MJ·mm)/(hm2·h); on the whole, rainfall erosivity shows an increasing trend year by year, but this trend is not significant. The results show that rainfall erosivity in Baiyangdian Basin shows a seasonal variation of high in summer and low in winter, and increases year by year as a whole. The elevation undulating zone and plain in the southwest-northeast direction have greater rainfall erosivity. Therefore, strengthening the monitoring of rainfall erosivity in key areas and important time nodes in the basin is a necessary guarantee for the prevention and control of soil and water loss.
