摘要:

为提升泰顺县农田灌溉能力,本研究以泰顺县农田灌溉系统为对象,基于该地区2007—2022年数据,选取农业总产值、粮食产量、农村可支配收入、农村恩格尔系数、第一产业总产值、农业机械总动力、有效灌溉面积、化肥施用量、农作物播种面积等9个指标,采用主成分分析法提取主成分并构建综合评价模型,分析泰顺县农田灌溉的影响因素。结果表明,前3个主成分可归纳为“灌溉基础设施因子”“种植结构因子”“农业投入因子”,累计方差贡献率达95.448%。分析发现,泰顺县农田灌溉情况的综合得分总体呈上升趋势,2014年后提升明显,但部分年份波动较大,反映出供水系统对外部冲击的脆弱性。基于分析结果,提出推进节水灌溉与韧性供水体系建设、优化“以水定产”种植结构、强化水源保护与绿色投入等建议,为提升该县农田灌溉能力提供改进方向。

Abstract:

In order to enhance the irrigation capacity of farmland in Taishun County,this study took the farmland irrigation system of Taishun County as the object. Based on the data of the region from 2007 to 2022,nine indicators(total agricultural output value,grain production,rural disposable income,rural Engel's coefficient,total output value of the primary industry,total power of agricultural machinery,effective irrigated area,fertilizer application amount,crop sown area)were selected,and the principal component analysis method was used to extract the principal components and construct the comprehensive evaluation model,to analyze factors influencing farmland irrigation in Taishun County. The results showed that the cumulative variance contribution rate of the first three principal components was 95.448%,which was summarized as irrigation infrastructure factor,planting structure factor and agricultural input factor. The analysis revealed that the comprehensive score for farmland irrigation in Taishun County showed an overall upward trend,and increased significantly after 2014,but fluctuated greatly in some years,reflecting the vulnerability of the water supply system to external shocks. Based on the analysis results,some suggestions were put forward,such as promoting the construction of water-saving irrigation and resilient water supply system,optimizing the planting structure of "yield based on water",strengthening water source protection and green investment,so as to provide direction for improving the farmland irrigation capacity of Taishun County.

Key words: Taishun County, principal component analysis, effective irrigation area, farmland irrigation, water-saving irrigation
