摘要
潜在的气象风险源就是具有高影响的空气事件.以南阳市为例,通过问卷调查,结合条件价值评估方法(contingent valuation method,CVM),评估南阳市居民对潜在的气象风险源发生时的支付意愿.结合2016年到2020年南阳市与公众密切相关的高影响空气事件主要为:"暴雪、大雪、雾霾、暴雨、大雨、中雨、高温、桑拿天、大风、寒潮等高影响空气事件.评估这些高风险空气事件的公众关注程度和公众的支付意愿.通过调查评估表明当暴雪、大雪、雾霾、暴雨、大雨、中雨、高温、桑拿天、大风、寒潮等潜在风险源发生时,南阳市民愿意支付的人均值分别为116.20、72.38、103.57、81.90、48.57、32.38、62.62、72.86、62.38元/a和74.05元/a.南阳市居民个人每年对所有潜在气象风险源愿意支付726.91元/a.最后根据结果对南阳市气象服务的社会影响力做出有效判断.
