摘要:
为了掌握川滇地区干旱灾害空间分布格局,采用熵组合权重、自然灾害风险指数法对川滇地区干旱灾害进行了风险评价与区划研究.研究发现:干旱灾害的高、较高风险区主要集中在川西高原和云南大部分地区; 高、较高、中等、较低、低干旱灾害风险区分别占川滇总面积的3.02%、29.24%、42.80%、24.93%和0.01%; 干旱趋势、致灾因子、孕灾环境是影响干旱灾害风险的主要因素.
Abstract:
To get the spatial law of drought disaster, the drought disasters are analyzed in Sichuan-Yunnan region by using methods of entropy weight combination and the natural disaster risk index. Results show as follows: the high risk region of drought disasters is mainly in Western Sichuan Plateau and the southwestern Yunnan region. The highest, high, medium, low, lowest drought disaster risk areas are respectively 3.02%, 29.24%, 42.80%, 29.24% and 0.01%. Drought trend, disaster-inducing factors, hazard inducing environment are the main factors affecting the drought disaster risk.
