摘要
在自然景观类型的卫星图像解群和制图的基础上，通过对自然景观类型分布规律的定性分析和定量计算，自下而上归并与自上而下划分相结合，将华中地区划分为５个自然区，２０个自然亚区和３１个自然小区。
Through detailed analysis of the differences (△T)between mean air temperature (T) in different time scales (year, half year, season, month, every ten days) from 1981 to 1994 and in contrast with those from 1961 to 1980 for 71 meteorological stations in Hubei Province (HB),it is found that: ①yearly △T is very small, but the geographic scales and variation of △T<0 are relatively wide and the distributions of T for season, month and every ten days in a year have shifted greatly and have apparant geographic differences; ②The winter is getting warmer, the summer is getting cooler and it is getting cooler in early spring and warmer in late spring ,but autumn has the reverse tendency of spring.The cooler summer and warmer spring is the most apparant. The (mountainous) western Hubei is getting cooler throughout the year.
