摘　　要：[目的]为促进风能资源开发的持续健康发展,为内陆地区风能资源的合理开发及利用提供科学依据,文章重点分析山区丘陵与平原湖区主要风能参数特征及差异。[方法]选用11个塔高为90~150 m的测风塔1整年观测资料,对湖北省山区、丘陵、平原及湖区等5种不同地形形态下的主要风能参数特征及差异进行探讨。[结果]分析结果表明:(1)各塔高层风速日变幅在1.0~2.3 m/s,山区丘陵地形下变幅明显大于平原湖区,且各层变化趋于一致,均为白天小晚上大,平原湖区低层风速日变化与高层特征相反,为白天大晚上小;(2)各塔综合风切变指数在0.055~0.328之间,在山区丘陵地形下大于平原湖区,风切变指数日变幅在0.063~0.378,变化特征为白天小晚上大,平原湖区风切变日变幅明显大于山区丘陵,大风情况下的风切变在山区丘陵地形下分布较为离散,平原湖区地形下则相对较为集中,基本稳定在0.1~0.2之间;(3)各塔高层有效风速段年平均湍流强度为0.13~0.18,山区地形下大于平原湖区,各塔湍流强度日变幅在0.07~0.15,变化特征均为白天大晚上小,但山区丘陵地形下变幅明显大于平原湖区。[结论]不同地形下的风能资源特征在动力和热力作用下表现出明显的时空变化差异,分析结果可为风能资源开发利用提供指导。[Introduction]In order to promote the sustainable and healthy development of wind energy resources and provide a scientific basis for the rational development and use of wind energy resources in the inland areas,the paper analyzes the characteristics of the main wind energy parameters and their differences between the mountainous,hilly,plain and lake areas.[Method]We used the observation data of 11 wind masts with heights of 90~150 m distributed in five different terrains of mountainous,hilly,plain and lake areas in Hubei Province for a whole year,analyzed the characteristics of the main wind energy parameters and their differences between the mountainous,hilly,plain and lake areas.[Result]The analysis results show that:(1)the daily variation of wind speed at the upper level of each mast is in the range of 1.0~2.3 m/s and is significantly larger in the mountainous and hilly terrain than in the plain and lake areas,and the variation tends to be consistent at various levels in that it is small during the day and large at night,while in the plain and lake areas,the daily variation at the lower level has opposite characteristics to the upper level and is large during the day and small at night;(2)the composite wind shear index of each mast ranges from 0.055~0.328,which is greater in the mountainous and hilly terrain than in the plain and lake areas,the daily variation of wind shear index is from 0.063~0.378,which is small during the day and large at night and significantly larger in the plain and lake areas than in the mountainous and hilly areas,and wind shear under high wind conditions is more discrete in the mountainous and hilly terrain and more concentrated in the plain and lake terrain,basically stable between 0.1~0.2;(3)the annual mean turbulence intensity in the effective wind speed section at the upper level of each mast is 0.13~0.18,which is greater in the mountainous terrain than in the plain and lake areas,and the daily variation of turbulence intensity in each mast is from 0.07~0.15,characterized in that
