作者研究了基拉的温暖指数(Wi)与其他四个重要的温度指标的关系：5℃以上和10℃以上的日平均气温之和，Thornthwaite的潜在蒸散量(PE)和Holdridge的年生物温度。利用均匀分布在中国各地的671个气象站的热力记录进行了对比。在这四个关系中存在着密切的相关性，相应地，我们用加权平均分析了主要植被类型的温度分布。671个站点周围的植被类型是从比例尺为1/4000000的植被图中读取的。269个站点的植被类型对应于自然或半自然植被，通过将269个数据划分为相同或相似的类型，可划分出29个植被类型。描述了这29个类型的地理分布和相应的主要气候特征。文中详细讨论了各植被类型的植被指数与分布的关系。结果表明：(1)北极或高山植被带：0-15；(2)北方或亚高山植被带：15-(50-55)；(3)冷温带植被带：(50-55)-(80-90)；(4)暖温带植被带：(80-90)-(170-180)。这些价值观几乎与基拉的价值观一致。
The authors examined relationships between Kira's warmth index (WI) and four other important thermal indices: the sums of daily mean temperature above 5.degree.C and 10.degree.C, Thornthwaite's potential evapotranspiration (PE) and Holdridge's annual biotemperature. The thermal records of 671 meteorological stations evenly located all over China were used to make these comparisons. Close correlations were found within the four relationships, and accordingly WI was used to analyse the thermal distributions of the main vegetation types. Vegetation types around the 671 stations were read from a vegetation map with a scale of 1/4000000. Vegetation types at 269 stations corresponded to the naturl or seminatural vegetation, and 29 vegetation types were distinguished by arranging the 269 data into the same or similar types. The geographical distribution of these 29 types and the corresponding main climatic features were described. The relations between WI and distribution of these vegetation types were discussed in detail. As a result, WI values (.degree.C month) corresponding to the vegetation zones could be summarized as follows: (1) arctic or alpine vegetation zone: 0-15; (2) boreal or subalpine vegetation zone: 15-(50-55); (3) cool-temperate vegetation zone: (50-55)-(80-90); (4) warm-temperate vegetation zone: (80-90)-(170-180). These values almost coincided with Kira's values.
