- 摘要:
- 通过对抚河历史洪水位流量关系及大断面等水文情势分析，发现水文情势变化与水土流失有着较紧密的联系。水文情势变化主要表现在（1）在相同流量状况下，水拉抬高；（2）洪峰时间滞后或提前。而水土流失造成河道泥沙淤积，河床抬高，是引起水文情势变化的主要原因之一。资料分析表明李家渡水文站测流断面河床自1982年至今，最大淤积达1 m以上，断面平均淤积在0.8 m，临川市以上的河床已抬高2～3 m，最高的达4 m之多。可见水土流失是导致洪水产生的重要原因之一。
- Abstract:
- The author analyse the history stage-discharge relation and large section and so on. The results showed that close relation between water and soil and hydrology situation is as follows: riverbed raise in the same discharge; flood peak time put off or move up. From 1982 up to now, riverbed of discharge site on Lijiadu hydrologic station has become silted up is more than 1m and the section average silted 0.8 m. The riverbed has raised 2～3 m and the biggest is more than 4 m above the city of Linchuan. In sight, water and soil loss is one of important reason on flood.
