摘　　要：利用MM5作为风能模拟模式,以地形复杂、气候背景特殊的海陵岛地区为研究区域,采用甚高分辨率(水平分辨率200m,最高垂直分辨率是10m)的模式设计,模拟了秋季海陵岛地区的风资源分布。研究表明,中尺度数值模式MM5的甚高分辨率的模式设计可以作为复杂海岛地形风资源评估的有效手段;海陵岛地区有效风能密度的大值区多数位于150～200W·m^(-2)之间,这说明我国沿海地区复杂地形地貌条件下潜在的风能资源完全可以开发利用,并需要更加深入而客观的评估。The Mesoscale weather numerical model, MM5 with high resolution, （the horizontal resolution is 200m, the highest vertical resolution is 10m） was designed to be up to the wind power assessment, and the initial field and boundary condition were combined with the meteorological elements＇ climatic background and the routine and non-routine weather observation. Hailing Island was used to be the research zone because of the complex terrain and special climatic character. Two conclusions were given from the study, the MM5 and the special can be used to assess the wind power in the complex topography, the potential wind power resource from 150 to 200 W·m^-2 of wind energy density at the complex topography in the coastland of China is rich enough to be exploited, and the assessment should be lucubrated objectively.
