摘要:
通过对延庆县康庄地区3种人工植被（林带、片林、杏园）不同部位的风速、积沙量、积沙形态特征以及林地土壤养分的观测与分析，比较不同植被类型防风、阻沙效益及土壤改良效益的差异；研究结果表明：在迎风面1H-10H范围内片林的防风效能最大为25.6%；在林内距迎风面1H-7H范围内杏园防风效能最大为70.0%；在背风面1H-20H范围内防护林带防风效能最大为32.3%。其阻沙量从小到大序列为林带、片林、杏园；在植被的作用下其积沙形态呈现不同的分布规律。3种植被的土壤改良效果明显，杏园改良效益最佳。
Abstract:
Based on the observations and analysis on average wind velocity, sand deposit and soil nutrient of woodland at multi-position of three types of artificial vegetation, including apricot orchard, forest belt and patch forest, and analyzing the difference in benefit of wind prevention, sand resistance and soil improvement among the three types of artificial vegetation, the result shows: (1) Patch forest has the most effective function of wind prevention in 1H-10H from windward side, with the protective ratio of 25.6%; apricot orchard has the most effective function of wind prevention in 1H-7H from windward side, with the protective ratio of 70.0%; forest belt has the effective function of wind prevention in 1H-20H from leeward side, with the protective ratio of 32.3%. (2) The order of the three type of artificial vegetation on sand resistance is forest belt
