| 1. | 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 |
| 2. | 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。 |
| 3. | There is also a difference in all rivers in this region . annual runoff of wudinghe river reduced notably in both general tendency and periodic change
陕甘宁地区河流径流量总的变化趋势为减少，但各条河流变化情况不同。 |
| 4. | In this paper , the characteristics and tendency of annual runoff changes of wudinghe river , malianhe river and qingshuihe river are analyzed
河流径流量在自然和人为因素的共同影响下而变化，变化特征复杂，趋势具有不确定性。 |
| 5. | 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。 |
| 6. | The impact of human activity on the runoff decline is obviously strengthening , and has already occupied a leading position in recent years
在这个背景下，人为因素的影响程度在明显增强，可以认为人类活动因子是河流径流演变的主要驱动因子。 |
| 7. | 2 . po4 - p budget in jiaozhou bay : seawater - accommodated po4 - p in jiaozhou bay is attributable to discharge from the rivers around jiaozhou bay and input from seawater - bottom sediments exchanging , and output to huanghai sea by hydrodynamic process
河流径流输入、沉积物释放和大气沉降是胶州湾海水中din的主要外部来源，由浮游生物活动而在水体中再生的din是胶州湾海水中din的内部来源。 |
| 8. | In a year the change of river flow is drastically and season distributes of runoff in river is mainly centralize in the summer in jia - lu - he , qiu - shui - he and pian - guan - he catchments . for example , the runoff amount from july to august accounts for 41 % , 58 % and 57 % of the annual runoff amount in the above three catchments , respectively
所选四条流域中，佳芦河、湫水河和偏关河三条河流径流量年内变化剧烈，季节分配不均，集中度高， 7 8月份径流量分别占各流域年径流量的41 、 58和57 。 |
