江西风能资源分析

Resources of Wind Energy in Jiangxi

本文根据江西,常澳辏ǎ保梗担～1980)气象资料,分析了江西风的分布特征和风能资源,分析指出:江西属季变型风向,冬季盛行偏北风;夏季盛行偏南风;年盛行风向为偏北风,因此全省绝大多数城市的工厂和居民区应分别设在东、西两侧,以便减轻和避免城市污染。分析还指出:江西年均风速、风压和有效风能密度,都以鄱阳湖盆地区最大;河各地区次之;丘陵地区最小,所以鄱阳湖沿岸各县,以及庐山、井冈山和南城等是风能资源可开发利用区。

This paper analyses the distribution features of wind and wind energy resources in Jiangxi. The results showed that wind direction is the seasonal transition, northerly in winter, southerly in summer, and annual prevailing wind is northerly. All of the annual mean wind speed,wind pressure and effective wind energy density are maximums in POYANG Lake region, mediums in river valley, and minimums in mountain land and hill region. Countries along the POYANG Lake coast and Lushan. Jinggangshan and Nancheng country are reasonable utilization regions for resouces of wind energy.
