摘要:

根據(jù)天津市靜海區(qū)18個(gè)鄉(xiāng)鎮(zhèn)2009—2018年逐時(shí)降水量,以及社會(huì)經(jīng)濟(jì)、地理地形、水利設(shè)施等數(shù)據(jù),結(jié)合歷史受災(zāi)信息,分別對(duì)靜海區(qū)的暴雨致災(zāi)因子危險(xiǎn)性、孕災(zāi)環(huán)境敏感性、承災(zāi)體易損性及防災(zāi)減災(zāi)能力進(jìn)行分析,采用GIS技術(shù)和統(tǒng)計(jì)方法多因子疊加,綜合得出靜海地區(qū)暴雨災(zāi)害風(fēng)險(xiǎn)精細(xì)化評(píng)估和區(qū)劃。研究發(fā)現(xiàn),靜海區(qū)北部區(qū)域以及南部中旺鎮(zhèn)及其周邊風(fēng)險(xiǎn)較高,而靜海地區(qū)中部的風(fēng)險(xiǎn)較低;暴雨災(zāi)害高風(fēng)險(xiǎn)區(qū)主要分布在致災(zāi)因子敏感性、承災(zāi)體易損性較高而防災(zāi)減災(zāi)能力較低的靜海鎮(zhèn)和梁頭鎮(zhèn)及其周邊,應(yīng)加強(qiáng)防災(zāi)減災(zāi)設(shè)施建設(shè)。

Abstract:

Based on the precipitation data, socioeconomic, geographic topography and water conservancy facilities in Jinghai District of Tianjin City from 2009 to 2018, the risk factors of disaster causing factors, the sensitivity of disaster sensitive environment, the vulnerability of disaster bearing body and the ability of disaster prevention and reduction were analyzed, respectively. The risk assessment and zoning of rainstorm disaster in Jinghai area were carried out by using GIS technology and statistical method. The study found that the risk of rainstorm disaster in Jinghai District of Jinghai city was evaluated and zoning. There is a higher risk in the northern part of Jinghai district and in the Zhongwang town and its surrounding areas, while the risk in the central part of Jinghai is relatively low. The high risk areas of rainstorm are mainly distributed in the Jinghai town and Liangtou town and its surrounding areas with the sensitivity of disaster causing factors, the high vulnerability of the bearing body and the low ability of disaster prevention and reduction, and the construction of disaster prevention and mitigation facilities should be strengthened.
