Analysis on Temporal and Spatial Distribution Characteristics of Hail Disasters in Heilongjiang Province
摘要
Abstract
The temporal and spatial distribution characteristics of hail disasters in Heilongjiang province were analyzed based on grey theory and the survey data of meteorological disasters to understand the history characteristics of hail disasters in Heilongjiang province. The results showed that：The hail disaster occurred mainly from May to October,and rarely in April and September,and most in May and June,followed by July and Sep- tember. Hail frequency slowly decreased with the time. The affected crops~ area and comparable economic los- ses caused by hail were more before the early 1990s, reduced in the mid-1990s,and increased slightly in the late 1990s. Hail disasters areas in Heilongjiang province were divided into heavy hail disaster area,medium hail dis- aster area,light hail area and micro-hail area. The heavy hail area referred to Jiamusi city,Suihua city,Jixi city, Heihe elty, Hegang city, Harbin city and Qiqihar city,Light hail area and micro-hail area were located in Yichun city and Greater Hinggan Mountains areas, which were in the north of Heilongjiang province. The heavy hail area were the main grain producing areas in Heilongjiang province, where had developed economy,prosperous culture,dense population and had extremely fragile meteorological disaster carriers. The light hail areas were mainly forestry,which had very small acreage of agriculture, and had relatively sparse population density, so it had less affected hail damage.关键词
