莆田文旦柚气候品质认证

Climatic Quality Certification of Wendan Pomelo in Putian

为了提升莆田市文旦柚的品牌效应和市场竞争力,利用文旦柚种植区历年区域自动站气象观测资料及果实品质检测数据,通过分析影响文旦柚品质的关键气象因子和主要气象灾害,构建文旦柚气候品质评估指标,采用专家打分法和层次分析法,确定气候适宜性因子和致灾因子的权重,建立文旦柚气候品质评估模型,计算气候品质指数并进行量化等级划分,开展文旦柚气候品质评估。结果表明:基于气候适宜性和气象灾害指标的文旦柚气候品质评估模型,模拟结果能定量化地反映气象条件对文旦柚品质的影响,结合其与实测果实品质、历史典型年果实品质及不同海拔区域果实品质的对比验证,气候品质评估结果与果实品质具有高度吻合性,能较好地反映文旦柚果实的实际品质,评估模型和评估结果较为客观,可为莆田市文旦柚气候品质认证提供技术支撑。

In order to improve the brand effect and market competitiveness of Putian Wendan pomelo,the climatic quality evaluation targets are built by analyzing the key meteorological factors and major meteorological disasters affecting the fruit quality based on the observational data of regional automatic stations over the years,and quality test data in pomelo’s planting area.Using the expert scoring method and analytic hierarchy process,the weights of climatic suitability factors and hazard inducing factors are determined.The climatic quality evaluation model is established,and the climatic quality index is calculated and quantitatively graded to carry out the climatic quality assessment.The results show that simulative results of the climatic quality evaluation model based on climatic suitability indicators and meteorological disaster ones can quantitatively reflect the impact of meteorological conditions on the quality.Compared with the actual fruit quality,fruit quality in typically historical years and fruit quality in different altitudes,the climatic quality evaluation results are highly consistent with fruit quality and can reflect the actual quality fairly.The evaluation model and results are objective,which can provide technical support for the climatic quality authentication of Putian Wendan pomelo.
