摘　　要：利用中尺度MM5和小尺度CALMET相结合的风能资源数值模式,对广西壮族自治区(以下简称"广西")2009年6月到2010年5月期间的风速、风功率密度等风能资源参数进行数值模拟,给出广西风能资源高分辨率分布图,并利用广西风能专业观测网的6座测风塔实测数据对模拟效果进行验证。结果表明:模拟结果合理,效果较好,70 m高度风速平均模拟误差为7.88%,符合广西风能资源的成因、气候特征和地形分布特点,能够宏观地反映广西风能资源的分布特征;总体上广西具有桂北、桂南海拔较高的山区和北部湾沿海地区风能资源较大及西部丘陵地带和东部河谷平原风能资源偏小的特点;冬季是风能资源利用的最佳季节,春秋次之,夏季较小。建议考虑在模拟资源较丰富的地区设塔进行观测评估,进一步明确该区域风能的资源量和实际分布状况。Numerical mode for wind energy resources combining mesoscale MM5 and small scale CALMET is used for numerical simulation on wind energy resources parameters including wind speed,wind power density,and so on during the period from June in2009 to May in2010 in Guangxi zhuang autonomous region（thereafter as Guangxi）.High resolution distribution diagram of wind energy resources in Guangxi is provided as well and test data from six anemometer towers of Guangxi wind energy professional observation network verifies simulating effects.Results indicate that simulating effects are reasonable and good.It is concluded that average simulation error of wind speed at 70 m height is 7.88% which accords with factors for Guangxi wind energy resources,climate characteristics and topographic features and is able to macroscopicly reflect distribution characteristics of wind energy resources in Guangxi.As a whole,wind energy resources in those high elevation mountainous areas in north Guangxi,south Guangxi and Beibu gulf coastal areas are abundant while in western hilly land and eastern river valley plain are fewer.Winter is the optimal season for wind energy resources utilization,spring and autumn takes second place and summer is the lesser.It is suggested to establish anemometer towers and carry out observation and evaluation in simulating areas with abundant resources so as to further make clear wind energy resources and actual distribution.
