近年来,无污染、可再生的绿色能源——风能,其潜在的价值逐渐被开发与利用。为了更加合理地利用河南省风能资源及研究气候变化条件下河南省风能的变化趋势,论文利用1971—2000年期间的河南省气象台站风速资料,采用统计方法和流体力学风能计算方法,结合ArcGIS系统对河南省的风能及分布进行了研究。研究结果表明:①特殊的地形特征造就了河南省风速较大区域主要集中在豫北、豫中、豫东的平原地带及豫南,西部及北部太行山区平均风速相对较小,区域风速差值较大;②30 a间河南大部分区域的风速变化为逐渐减小趋势,只有个别站点风速表现为趋势略增或趋势稳定;豫东为风速减小最大的区域,豫西、豫中及豫南地区风速变化趋势相对较小;③风能研究发现最大值区域与平均风速地理分布基本一致,最大风能区域在豫北、豫东、豫中及豫南一带,最小风能区域主要集中在西部山区。

In recent years, wind power, a non-polluting, renewable green energy, has been developed and utilized faster than ever. For better utilization of wind energy resources and understanding wind energy changing trend under climate change condition in Henan Province, the spatial-temporal distribution of wind energy was studied in this paper with the meteorological data from 1971 to 2000, the statistical methods and wind energy calculation methods in hydrodynamics were used in this paper. The results show: 1) the special terrain characters create the features of higher wind speed mostly clustered in plain areas of northern Henan, central Henan, eastern Henan as well as southern Henan, western Henan is a zone with lower wind speed. 2) The wind changing trend reduced gradually from the 1970s to the 2000s in most parts of Henan Province except several districts. Eastern Henan has been tested to be the most serious zone in wind speed decrease, and other parts of Henan have a relative less value in wind speed decrease. 3) Wind energy's distribution was the same as wind speed, the highest wind-energy zone clustered in northern Henan, central Henan, eastern Henan and southern Henan, western Henan is a zone with lower wind energy.
