Abstract: Based on the conventional meteorological data of temperatuer,wind-speed,relative humidity,sunlighr from 11 meteorological observation stations in Dezhou City from 1967 to 2017, the temperature humidity index (THI) , wind effect index(K),clothing index(ICL) and comprehensive comfort index were calculated and analyzed in detail. The linear trend approach was adopted to analyze the variation characteristics for each index over the recent 50 years. The results indicated that:(1) The period,within a year, for climate suitability at the comfortable level was longer than 7 months, and was about 5 months at the less comfortable level. April and October were the most comfortable months for climate-suitability of the year, and January was the most uncomfortable month of the year. (2) The monthly the temperature humidity index (THI) and wind effect index(K) showed a significant upward trend, while the clothing index showed a significant falling trend. The comprehensive comfort index showed an upward trend in winter and basically showed a downward trend in summer. (3) The year-round climate in Dezhou was relatively at the uncomfortable and comfortable levels. The climate in most years was at the more comfortable level. The climate of the city was at the comfortable and more comfortable levels in spring and autumn, which was at the less comfortable level in summer, and was at the less comfortable and uncomfortable levels in winter. As the climate warms, the comfort period in Dezhou was prolonged, showed a good climate suitability for human settlements.
