| 5. | The rainfall erosivity is mainly distributed in the period from april to june for the stations of guangzhou , shaoguan and heyuan , and from june to august for other three coastal stations , namely shantou , shanwei and yangjiang 降雨量与降雨侵蚀力集中度的分布规律一致,但与降雨量相比,降雨侵蚀力的分布更加集中。 |
| 6. | The tendency of precipitation and rainfall erosivity is all positive in the 6 stations , that shows that they have been increasing since 1954 , and the increasing extent of rainfall erosivity is greater than that of precipitation 各站降雨量与降雨侵蚀力的倾向率均大于零,说明自1954年以来,雨量和降雨侵蚀力均有不同程度的增加趋势,降雨侵蚀力的增幅远远大于降雨量的增幅。 |
| 7. | Ii ) runoff erosivity reflects relationship of water erosion forces and sediment yield more directly than rainfall erosivity . it intergrated ability of runoff volume and flood peak on detaching soil and transporting sediment and is more reasonable than single runoff depth or flood peak volume ( 2 )以径流侵蚀力代替降雨侵蚀力来反映水蚀营力与产沙量的关系更加直接,而且综合了径流量与洪峰在剥蚀土壤和搬运泥沙能力,比单独运用径流深或洪峰流量更加合理。 |
| 8. | Results from weather monitoring stations from the area showed that precipitation in the two months accounted for 37 . 70 % total annual rainfall during the year under review and a significant positive correlation between the rainfall erosivity and rainfall intensity was found , which indicated that the erosive ability of rainfall could be better expressed by its intensity than the total amount of rain 2001年研究区降雨量和降雨侵蚀力均为6 、 8月较大,其中6 、 8月降雨量为全年的37 . 70 ;降雨侵蚀力与可产生侵蚀雨量为极显著正相关,可侵蚀降雨量比降雨量能更好地表示降雨的侵蚀能力。 |
| 9. | Relationship model among topography fractal dimension , runoff eroding power and sediment transport modulus was established after proposing topography fractal dimension as comprehensive quantitative index for topography by replacing rainfall erosivity with runoff erosivity . based on this model , relationship between watershed topography parameter and sediment yield were setup using the observed data from cha bagou watershed , together with parameter calibration 提出了以地形分维数作为地貌形态综合量化的指标,以径流侵蚀力代替降雨侵蚀力的思想,建立了模型流域地形分维数、径流侵蚀力与输沙模数之间的关系模型;在此基础上,应用岔巴沟流域实测资料,建立了流域地貌形态参数与侵蚀产沙关系模型,并进行参数率定和检验。 |
