摘要: 为了客观定量地评估气象预报(以大风为例)为农业生态(以日光温室为例)服务的经济效益。依气象产值和实际预报信息,笔者构建了信息—实况矩阵,并将信息—实况积事件、信息—实况概率的通用概率—集合用公式表达出来。给出了评价的通用方法,说明以气象产量概念为基础的产值评估原理。以大风预报为日光温室(大棚)服务的实际观测数据为信息源,经由计算得出如下结果:喀左县全县的总经济效益为6304×104元/a;效益损失比为65.6:1。理论解析和计算实例表明:本研究提出的原理和方法,可用于全县生态经济效益评估的相关领域。

Abstract: This paper aims to make an objective and quantitative assessment of the economic benefits of meteorological forecasts in serving agro-ecology. The author built an information-state matrix, and provided the general mathematical formulae for the probability sets of the product- events of information- state probabilities. The result showed that the general methods were applicable to such an assessment. The authors described the basic principles on the concept of meteorological yields. Those practical observation data in Kazuo of 1999-2013 were taken as information resource to forecast fresh gale and serve sun-light greenhouses in Kazuo, and the authors obtained the following computed results: (1) the total economic benefit in Kazuo was 6304×104 yuan/a; (2) the benefit-cost ratio was 65.6:1. From the above research, the author drew conclusion that both principles and methods mentioned above might be applied to the relevant fields of evaluations on meteorological- ecology economic benefits.
