摘要:本文旨在对内蒙古西部乌兰布和沙区周边绿洲农区防护林体系的气候生态效益进行评价,并分析三北防护林工程建设之前、三北防护林工程一期工程和二期工程3个时期的变化趋势,建立防护林体系变化与气候变化的关系模型。研究结果表明:(1)防护林体系的变化对气候因子风速、大风日数、扬沙日数、沙尘暴日数有一定的影响,体现了防护林体系的生态屏障作用;(2)防护林体系的变化对年平均温度、湿度、降水量、持续干旱日数和霜期等因子影响不明显,这是因为这些因子的变化主要受大气环流控制所致。
Purpose of this article is to evaluate the climatic and ecological effects of protection forest in surrounding green land area of west Wulanbuhe Desert in Inner Mongolia, analyze change tendency of climatic and ecological effects with forest cover rate change during prior, first and second phases to construction of the 'Three North' protection forest. The results show that (1) change of protection forest influence calamity climatic factor (wind speed, gale days, raising sand days, and sand storm days). Protective forest produce protective screen effect. (2) change of protection forest can't influence routine climatic factor (temperature, humidity, precipitation, continue dry days, and frost season), because those climatic factors are control mainly by atmospheric circulation.
