2025年全国风能资源评价报告：31省市风速、风功率密度对比分析

Core Insights - The report from Huafeng Innovation Research Institute indicates that the national wind energy resources for 2025 are expected to be normal, with the average wind speed at 10 meters height being 0.41% higher than the average of the past decade (2015-2024) and 0.23% higher than in 2024 [1][4][24]. Wind Speed Analysis - The average annual wind speed at 70 meters height across provinces ranges from 3.9 m/s to 6.5 m/s, with Liaoning and Inner Mongolia exceeding 6.0 m/s [2][25]. - The average annual wind speed at 10 meters height is reported to be lower in provinces such as Heilongjiang, Shanghai, Guizhou, Yunnan, Hunan, Guangxi, and Hebei, while provinces like Jilin, Shaanxi, Hubei, Shanxi, Anhui, Shandong, Hainan, Chongqing, and Henan show higher than normal speeds [5][26]. Wind Power Density Insights - The average wind power density at 70 meters height varies between 79.9 W/m² and 277.7 W/m², with six provinces (Gansu, Heilongjiang, Xinjiang, Jilin, Liaoning, and Inner Mongolia) having densities greater than 200.0 W/m² [2][25]. - Compared to the past decade, many provinces have average wind power densities close to normal, with notable increases in regions like Gansu, Shaanxi, Shanxi, and others, while areas such as Heilongjiang and Yunnan show decreases [14][34]. Year-on-Year Comparisons - In comparison to 2024, most provinces have similar average wind speeds, with Qinghai, Ningxia, Hainan, and Hebei showing increases, while Yunnan, Hunan, Liaoning, and others show decreases [2][25]. - The average wind power density for 2025 is expected to be stable across most provinces, with increases noted in Ningxia, Hainan, Qinghai, and others, while decreases are observed in Yunnan, Guangxi, Hunan, and others [2][25].
