摘要: 对克拉玛依农业综合开发区农田防护林林带有效防护距离和面积进行了研究。结果表明,开发区现有林网规划不合理,在达到防护成熟时,林带树高不能满足对所需防护的空间范围形成有效防护的要求。如果要形成有效防护,就需增加主、副林带的密度。一般风速条件下,中等立地条件主林带的间距应为270m,副林带间距以400m为宜。并得出开发区防护林网在降低风速20%~50%的条件下,有效防护面积百分比分别为16.55%,13.54%,10.65%,7.54%,4.87%,2.59%和1.12%。

Abstract: This thesis studies efficient protection distance and area of farmland protective forest in the comprehensive agricultural development area in Karamay. The results indicate that at present the program of windbreak is unreasonable. Under vested site condition, tree height which the windbreak can reach can not plays a role in protecting the farmland within the development when the windbreak becomes mature. In order to achieve efficient protection, increasing density of the main or subsidiary windbreak is feasible. The main and subsidiary windbreak’s space distance should be 270m and 400m respectively in common wind speed and medium site condition. At the same time, the area percentage of the efficient protection is 16.55%, 13.64%, 10.65%, 7.54%, 4.87%,2.59% and 1.12% respectively on the condition that the wind speed slows down 20%~50%.

Key words: Karamay, windbreak, efficient protection distance, efficient protection area
