福建主要城市周边平缓高地与避暑休闲气候关系分析

On the Relationship between Gentle Highlands around Major Cities in Fujian and their Climate of Summer Resort and Rest

针对酷热夏季避暑休闲的需要,根据福建主要城市周边普遍存在的平缓高地地形,用地形分析法提取了城市周边53片海拔500～1100m的集中连片平缓高地,总面积达366.2km2,分析其交通可达性,提出开发利用这些平缓高地作为避暑休闲用地的设想;根据气候要素特征空间变化的规律和地理相关法,从已有观测资料推测估算这些缺乏直接观测资料的平缓高地的多年平均月均温、月均高温、月均低温、日高温≥30℃和≥35℃的天数、月均降水量、月均相对湿度和日照时数等气候要素特征值,定性推测这些高地的风速,论证了这些高地具备良好的避暑休闲气候条件.

Supposing that the widespread gentle highlands around major cities in Fujian can meet recreational needs in hot summer season, Terrain Analysis is carried out to select 53 pieces of gentle highlands with a total areas of 366.2 km^2 around 500 - 1 100 m above sea level for the analysis of transportation accessibility. According to the spatial variation law of climate elements as well as geo- graphical correlation, the characteristics of climate elements on these highlands, such as average temperature for many years on, average monthly highest temperature, average monthly lowest temperature, number of the days with highest temperature ≥30℃ and ≥35 ℃, average monthly precipitation, average monthly relative humidity and sunshine hours, are estimated. And the wind speed of the highlands is also speculated in qualitative way. The present study has proved that these highlands would be well qualified to be developed as resorts and recreational places in hot season.
