【摘要】：我國是洪澇災(zāi)害頻發(fā)的國家之一,尤其長江在6-10月降雨量大而次多,極易引發(fā)洪災(zāi),嚴(yán)重威脅長江沿岸各區(qū)域的安全。如何在氣候變化和人類活動(dòng)雙重影響的新情勢下合理而有效地進(jìn)行區(qū)域洪水風(fēng)險(xiǎn)管理,是一個(gè)值得深入研究的問題。通過構(gòu)建區(qū)域洪水風(fēng)險(xiǎn)管理模型,并將其應(yīng)用于荊江河段區(qū)域,推演堤壩潰口條件下區(qū)域內(nèi)洪水變化過程,并評價(jià)出洪水對區(qū)域內(nèi)各要素的影響。所構(gòu)建的模型可靠、實(shí)用且結(jié)果合理,能夠?yàn)閰^(qū)域洪水風(fēng)險(xiǎn)管理和水資源保護(hù)、防洪減災(zāi)措施的制定提供一定的技術(shù)支持。
[Abstract]:China is one of the countries with frequent flood disasters, especially the Yangtze River, which has a heavy rainfall in June-October, which can easily lead to floods and seriously threaten the security of various regions along the Yangtze River. How to carry out the regional flood risk management reasonably and effectively under the new situation of climate change and human activities is a problem worthy of further study. By constructing a regional flood risk management model and applying it to the Jingjiang River reach, the process of flood variation in the region under the condition of dike burst is deduced, and the influence of flood on various elements in the region is evaluated. The model is reliable, practical and reasonable. It can provide some technical support for regional flood risk management, water resources protection, flood control and disaster reduction measures.
