白河烟区与国内外典型烟区气候相似性分析

Analyses on Climate Similarity between Baihe Tobacco Area and Others Tobacco Areas

通过与国内外典型烟区的气候特征的比较,可为耦合当地温、光、水资源,提高气候资源利用率、增强抗灾能力提供理论依据与实践参考。采用多维空间相似距离度量各地间的相似程度,比较了近20年白河烟区与国内外典型烟叶生产区的气象条件,并进行了相似性分析。结果表明:白河烟叶生长季节大田期平均气温、日照时数、降雨量、平均相对湿度均较适宜,但由于降雨量年际波动大、烟叶成熟后期存在高温,因此,白河烟区应采取适时早栽早收、改进栽培措施进行避免。白河烟区的气候条件与云南玉溪、巴西烟区的相似程度为较高相似,与美国和津巴布韦烟区的相似程度为中度相似。

It provides theoretical foundation and practical reference to couple temperature,sunshine and precipitation and improve climate resource utilization and enhance anti-disaster ability by comparison on climate characteristics between Baihe tobacco area and others areas.Comparison on climate conditions of recent 20 years between Baihe tobacco area and others areas and the analysis on similarity were carried out by adopt multidimensional space similar across the distance metric.The results were showed as follows： mean air temperature,sunshine hour,precipitation and relative humidity during flue-cured tobacco growth and development period in field were more appropriate,while inter-annual variation of precipitation was greater and high temperature in late maturity stage existed,Baihe tobacco area should advance planting and harvest time,and improve cultivation measures.In addition,the similarity in meteorological conditions between Baihe tobacco area and Yuxi and Brazil tobacco areas was higher,while that between Baihe tobacco area and American and Zimbabwe tobacco areas was moderate.
