| 1. | Study on relation between underlying surface and river runoff 下垫面与河川径流的关系研究 |
| 2. | The influence of human activities on river runoff rises notably 无定河流域河川径流的人类活动影响程度在显著上升。 |
| 3. | Qinhuangdao climate change ' s impact on river runoff volume and countermeasures 秦皇岛市气候变化对河流径流的影响及对策 |
| 4. | The analysis on the change characteristics and driving forces of wudinghe river runoff 无定河年径流量变化特征及人为驱动力分析 |
| 5. | Human factor have made the river runoff reduce more and more and they are becaming the driving force 人为因素使无定河流域径流量减少量越来越大。 |
| 6. | The decline of river runoff indicates the obvious trend of environmental aridity in the region 流域河川径流来源于降水,全球变化是河流径流量变化的背景。 |
| 7. | So further study on model of influence of human activities on river runoff change and simulation in different regions is necessary 所以人类活动因素影响下河流径流量变化模型及模拟还有待于针对不同地域、不同时空尺度做进一步的深化研究。 |
| 8. | These models can be used to estimate impact of control measures on river runoff , and to what degree these measures effect the runoff production in river catchments at any given year 该模型能分离水土流失综合治理对河川径流量的作用大小,并可估算任一年份水土保持措施对降雨产流量的影响程度。 |
| 9. | Firstly established plural linear regression model to estimate the river runoff uninfluenced by human . compare with the record of hydrology examinition stations , then analyze the influence degree of human factors , namely the diference of the two river runoff account 通过多元回归方程预测自然状态下陕甘宁地区河川年径流量,对比实测径流量来分析人为因素对径流量的影响程度。 |
| 10. | Although there are several studies on influence degree of human factors on river runoff , generally acknowledged model to appraisal the weight of human activities has not show yet at present because the regional natural conditions differ widely 国内虽有一些衡量人为因素对径流量影响程度的研究,但由于所处地区自然条件大不相同,所以目前尚无公认的评价人类活动因素在径流量变化原因中所占比重的模型可资借鉴。 |
