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。
The weak construction of farmland water conservancy facilities is considered to be an important cause of the increasingly serious disaster. The purpose of the study was to evaluate the drought response of different farmland water conservancy facilities in food production. Based on the large-scale field survey data of 7 provinces (cities), 123 villages and 1,162 households in China, on the basis of descriptive statistical analysis, the econometric model was used to quantitatively analyze the drought resistance effect of farmland water conservancy facilities. The results show that in the recent 5 years, one-third of farmers suffered a drought and reduced production, with a reduction of more than 25% of farmers accounted for 22%; large and medium-sized reservoirs, pools and pumps drought resistance was significantly higher than the river diversion channel The policy implications of the findings are discussed.
