| 7. | The temporal pattern of the 137cs deposition flux must be considered when developing calibration relationship between the loss or gain of and the rate of erosion or deposition
在建立~ ( 137 ) cs土壤侵蚀模型的过程中，对~ ( 137 ) cs的沉降过程的处理是正确估算土壤侵蚀速率的基础。 |
| 8. | Compared with jiang ' s regressive model , the soil rates by 137cs tracer is lower about 10 % than that by jiang ' s regressive mode when they has been used to estimate rates of soil loss on runoff plots
因此，在利用~ ( 137 ) cs技术示踪农耕地土壤侵蚀速率时，这四个模型各自计算的土壤侵蚀速率差异较小。在估算径流小区土壤侵蚀速率中各模型与江忠善经验回归模型的结果相差都在10左右。 |
| 9. | Their downcuting velocity accelerates except luohe river round luochuan . the erosion velocity of weihe river round tianshui and jinghe river round binxian reduced , and the lateral erosion velocity of luohe river round luochuan reduced . this may be due to the reduced flow
天水渭南镇段渭河、彬县段泾河的侵蚀速率呈脉动式减小，秦家河段洛河侧蚀速率逐渐减小，这可能与河水流量随时间推移逐渐减小有关。 |
| 10. | For the cultivated study field , the 137cs concentration is relatively uniform within the plough layer . 2 . the difference and sameness among the existing l37cs models have been discussed , and their precision have been validated by comparing with the regressive model of soil erosion
分析了~ ( 137 ) cs示踪农耕地土壤侵蚀速率模型间的异同，并以土壤侵蚀的经验回归模型为参照对~ ( 137 ) cs法计算的土壤侵蚀速率进行验证。 |
