| 摘要: |
| 利用1997～2007 年辽宁省7 个海洋站和2007～2008 年3 个临时观测站的实测数据, 使用GIS 的反距离加权插值法, 初步分析了辽宁省沿海风能资源时空分布。结果为: 辽东湾沿岸风能资源丰富, 年平均风功率密度可达250 W/m2, 大连南部和东南沿海风能资源次之, 年平均风功率密度达到175 W/m2,丹东沿海和大连东北部沿海属于风能可开发区, 年平均风功率密度仅有75 W/m2。辽宁沿海风能资源春季最丰富, 年平均风功率密度可达185W/m2, 秋季和冬季次之, 年平均风功率密度可达158 W/m2,夏季最低, 年平均风功率密度仅有88 W/m2。本研究初步掌握辽宁沿海的风能资源的分布规律, 对合理开发利用辽宁海岸带的风能资源和海洋功能区划修编有一定的理论依据和实用价值。 |

| Abstract: |
| The characteristics of wind energy along Liaoning coastal area were extracted from the wind data from 1997 to 2008 with the method of inverse distance weighted interpolation. The results show that the Liaodong Bay coastal area is rich in wind energy, which reaches 250 W/m2 per year. The wind energy in the south and southeast of Dalian coastal area reaches 175 W/m2 per year. Dandong and the northeast of Dalian coastal area is only a potential area for wind energy utilization, with a wind energy of about 75 W/m2 per year. In addition, the resources in the Liaoning coastal area in spring are relatively high, which is about 1.2 times of that in autumn and in winter, and 2.1 times of that in summer. This research has practical value to the rational utilization of wind energy resources along Liaoning coastal area and the divison of ocean functional area. |
