摘要: 农田水利设施建设薄弱被认为是导致灾情日益严重的重要原因。研究目的是评估不同农田水利设施在粮食生产中的抗旱效果。基于全国7省(市)、 123村和1 162户农户的大规模实地调研数据,在描述性统计分析的基础上,通过计量经济学模型,定量分析了农田水利设施的抗旱效果。研究结果表明,最近5 a内,有1/3的农户受旱灾而减产,减产25%以上的农户占到22%;大中型水库、 水池和水泵的抗旱作用显著高于河流引水渠道,文章对研究结果的政策含义做了讨论。

Abstract: Poor construction of rural irrigation infrastructure has been considered as one of the major reasons for increasing serious drought in agricultural production. The purpose of this paper is to evaluate the drought resisting effect of different irrigation infrastructures on grain production. On the basis of descriptive and econometric analyses, the paper quantitatively analyzes the effects of different irrigation infrastructures on drought resisting. The analyses are based on data collected from a large field survey with 1162 households from 123 villages in 7 provinces in China. Research results show that, in the recent five years, there were about 1/3 of farmers whose grain yield were damaged by drought. In addition, 22% of farmers lost grain yield by more than 25%. Among all irrigation infrastructures, larger and middle scale reseviors, ponds and water pump performed better than others on resisting drought. The paper also disscusses the policy implications of research results.

Key words: drought, irrigation infrastructure, drought resisting effect
