摘要
利用关联聚类法建立了湖南农业干旱脆弱性分区的指标体系。运用密切值法,建立数学模型,对湖南省97个县(市)进行了农业干旱脆弱性分区研究,并绘出了分区图。分区结果表明:极严重脆弱区11个,严重脆弱区23个,较严重脆弱区27个,一般脆弱区20个,轻度脆弱区16个。
In the paper, by using the method of incidence clustering, the index system for the frangibility zoning of agricultural drought in Hu＇nan Province have been established. This paper applied the near method to set up the mathematic model and carried out the zoning study for the frangibility of agricultural drought of 97 frangibility. The zoning result has shown that there were 11 extremely serious frangible regions, 23 serious ones, 27 under serious ones, 20 general ones and 16 light ones.
