哈尔滨市区洪灾风险空间演变模式
Drought risk space evolution pattern in Haerbin
摘要
Abstract
Haerbin city one of the typical cities with frequent floods in China ,and the region with occurrence of flood disaster changes every year .It would be beneficial if the disaster prevention and reduction department could make timely and accurate flood control planning by understanding the risk of flood disaster dynamic distribution rules .Firstly ,through the nature dis‐aster risk formation four‐factor theory ,assessment model of flood disaster risk of Haerbin Province was established ,using metrological ,hydrological ,social and economical features as indicators .Secondly ,comprehensive dynamic degree of flood risk in Haerbin from 2000 to 2010 was analyzed by means of the dynamic degree of single risk ,the dynamic degree of inte‐grated risk ,gravity center migration of risk and risk replacement coefficient .Mapping and analysis of the risk zoning of flood disaster w as conducted by GIS ,and the risk spatial evolution pattern w as classified .Seven risk spatial evolution patterns were included as follows :edge contact expansion ,inwards sudden increase ,swing ,leapfrogging ,marginal deflation ,internal sudden decrease and regional deflation .关键词
