摘要:

以1991a-2006a唐山地区夏粮作物旱灾面积为基础,从产量损失和经济损失两方面对旱灾损失进行了估算。结果显示:⑴1991a-2006a夏粮因旱累计减产17.99×108kg,平均每年减产1.12×108kg;产量损失最大年份为1999a(减产2.2×108kg),产量损失最小年份为2006a(减产0.2×108kg);(2)按1990a不变价格计算,累计经济损失15.3×108元,平均每年损失0.96×108元。按当年价格计算,累计经济损失19.6×108元,平均每年损失1.2×108元;(3)减产利润损失最大年份为1995a(利润损失为0.68×108元),利润损失最小年份为2000a(利润损失为-178.4×104元)。不变价格和当年价格计算的经济损失以及产量损失与利润损失间的非一致性,对农业保险政策的制定具有一定的借鉴作用。

Abstract:

Drought loss was estimated about the yield losses and economic losses, based on the drought area of summer crops in Tangshan from 1991 to 2006. The results showed that: (1)The total grain reduction of summer grain crops was 17.99×108kg from 1991 to 2006, the average annual cut was 1.12×108kg;Maximum Year of yield loss was 1999 (The cut was 2.2×108kg),Minimum Year of yield losses was 2006 (The cut was 0.2×108kg).(2)According to the constant price of 1990, the total economic loss was 15.3×108 yuan, the average annual loss was 0.96×108yuan. According to the current price, the total economic loss was 19.6×108yuan, the average annual loss was 1.2×108yuan. (3)Maximum Year of profit loss was 1995 (The profit loss was 0.68×108 yuan), Minimum Year of profit loss was 2000 (The profit loss was-178.4×104 yuan). Economic losses and yield loss according to the constant and current prices was non-consistency relative to profits loss, which has a certain reference for the development of agricultural insurance policy.
