| 摘 要： | 为了研究三北防护林工程对科尔沁沙地生态环境改变所起的作用，为后期工程的规划编制提供依据，根据其最典型地区1961—2010年的气象资料，对三北防护林体系建设前后的平均风速、大风、沙尘天气进行对比分析。结果表明：近20年来，科尔沁沙地年平均风速稳定在3.2~3.3 m/s之间，风沙天气呈急剧下降趋势，到1995年基本得到遏制。三北防护林工程对科尔沁沙的生态环境和农牧业生产起到了不可或缺的保护和调节作用。

| Abstract: | In order to study the role of Three North Shelterbelt Project on ecological environment change in Horqin sandy land, for providing the basis for later engineering planning. According to the most typical region 1961-2010 years of meteorological data, the average wind speed, wind and the dust weather before and after Three North Shelterbelt Project construction were analyzed. The results showed that: in the recent 20 years, the average wind speed was 3.2-3.3 m/s between fluctuation in Horqin sandy land, sandstorm weather was a sharp decline trend, by 1995 be contained. Three North Shelterbelt Project played an indispensable protection and control effects on the ecological environment of the well-kown Horqin sand production, farming and animal husbandry. |
