中文摘要:

近年来河北省多个城市频繁遭受内涝威胁,本文选取石家庄、保定、邯郸、邢台、廊坊、唐山6个市城区代表河北省主要城区,通过资料查询和网络媒体收集得到这6个市城区2012-2022年的积水点数据,并通过ArcGIS制图,分析出河北省主要城区内涝的分布特征。结果表明河北主要城区内涝具有以下特征:(1)6个城市城区积水点的总数呈波动增加趋势,年均约45个积水点,2016年、2021年最多,分别为128个、136个,其中石家庄和邯郸积水点呈现波动减少趋势;(2)3个城市的主要积水点空间分布出现了变化。石家庄市的内涝区由城区中心向城区外围转移,保定市的内涝区由城区中南部向北部转移,邯郸市的内涝区从集中在城区中东部变得分散。邢台市、廊坊市、唐山市等地的内涝区变化不大;(3)河北省6个城市约86%的积水点在2021年都已不再出现,说明这些点已基本治理完成。新出现的积水点,主要分布在新开发的地区,或者地势低洼、排水能力中下的地区,积水问题正在开始突显。(4)河北省6个城市都存在着易积水点,11年来共30个。以此讨论出针对河北省内涝防治的一些对策,如做好汛期前排查、增设雨水泵站、进行雨污分流、增设排水设施、加强监管措施落实等,以期对河北省的内涝防治做出一些贡献。近年来河北省多个城市频繁遭受内涝威胁,本文选取石家庄、保定、邯郸、邢台、廊坊、唐山6个市城区代表河北省主要城区,通过资料查询和网络媒体收集得到这6个市城区2012-2022年的积水点数据,并通过ArcGIS制图,分析出河北省主要城区内涝的分布特征。结果表明河北主要城区内涝具有以下特征:(1)6个城市城区积水点的总数呈波动增加趋势,年均约45个积水点,2016年、2021年最多,分别为128个、136个,其中石家庄和邯郸积水点呈现波动减少趋势;(2)3个城市的主要积水点空间分布出现了变化。石家庄市的内涝区由城区中心向城区外围转移,保定市的内涝区由城区中南部向北部转移,邯郸市的内涝区从集中在城区中东部变得分散。邢台市、廊坊市、唐山市等地的内涝区变化不大;(3)河北省6个城市约86%的积水点在2021年都已不再出现,说明这些点已基本治理完成。新出现的积水点,主要分布在新开发的地区,或者地势低洼、排水能力中下的地区,积水问题正在开始突显。(4)河北省6个城市都存在着易积水点,11年来共30个。以此讨论出针对河北省内涝防治的一些对策,如做好汛期前排查、增设雨水泵站、进行雨污分流、增设排水设施、加强监管措施落实等,以期对河北省的内涝防治做出一些贡献。

外文摘要:

In recent years, many cities in Hebei Province have been frequently threatened by waterlogging. In this paper, six cities and urban areas, Shijiazhuang, Baoding, Handan, Xingtai, Langfang and Tangshan, are selected to represent major urban areas in Hebei Province. Data of waterlogging points in these six cities and urban areas from 2012 to 2022 are collected through data query and network media, and then mapped by ArcGIS. The distribution characteristics of waterlogging in main urban areas of Hebei Province are analyzed. The results showed that waterlogging in the main urban areas of Hebei had the following characteristics: (1) The total number of waterlogging points in the urban areas of 6 cities showed a trend of fluctuation increase, with an average annual number of 45 waterlogging points, and the maximum number in 2016 and 2021 was 128 and 136 respectively, among which Shijiazhuang and Handan showed a trend of fluctuation decrease; (2) The spatial distribution of major water accumulation points in the three cities has changed. The waterlogging area of Shijiazhuang city is transferred from the urban center to the periphery of the urban area, the waterlogging area of Baoding city is transferred from the southern part of the urban area to the northern part, and the waterlogging area of Handan city is concentrated in the eastern part of the urban area. The waterlogging areas of Xingtai City, Langfang City and Tangshan city have little change. (3) About 86% of water accumulation points in six cities in Hebei Province no longer appear in 2021, indicating that these points have been basically completed. The new water points are mainly distributed in newly developed areas or low-lying areas with moderate drainage capacity, and the water problem is beginning to become prominent. (4) There are water-prone points in 6 cities in Hebei Province, with a total of 30 in 11 years. In order to make some contributions to the prevention and control of waterlogging in Hebei province, this paper discusses some countermeasures for waterlogging prevention and control in Hebei Province, such as doing a good job of pre-flood investigation, adding rainwater pumping stations, diverting rain and pollution, adding drainage facilities, and strengthening the implementation of supervision measures.
