神府东胜煤田扰动地面野外降雨试验
Field Rainfall Experiment on the Disturbed Lands During the Shenfu-Dongsheng Coalfield Exploitation
摘要
Abstract
Shenfu-Dongsheng coalfield has the largest proven reserves of coal in China.However,the exploitation of the Shenfu-Dongsheng coalfield badly disturbed the ground,which caused severely soil and water erosion.A field rainfall experiment on soil erosion,sediment yield and runoff yield on the disturbed lands was conducted to provide scientific date for predicting and controlling soil and water loss on the disturbed lands.Results indicated that rainfall intensity was a major impact factor in the runoff generation time,with the increase of rainfall intensity,the runoff generation time of disturbed lands decreased with the negative power function distribution range.Infiltration rate increased and then stabled with the increase of rainfall intensity and slope,but with the increase of slope,it changed not obviously.With the increase of rainfall intensity and slope,the runoff rate of disturbed roads increased within the power function distribution range.With the increase of rainfall intensity,the average sediment yield and erosion transport rate of disturbed roads increased with the power function distribution range.There was a linear regression between runoff amount and rainfall intensity,and a power regression between sediment yield and runoff amount,which had high correlation.关键词
