摘要:
通过野外调查与实验观测，对延庆县两种类型人工植被在春季对风沙阻滞规律进行分析研究，结果表明农田防护林带风速在林带后7H处降低最大，防风效能最大，杨树片林风速在9H处最小，防风效能最大；杨树片林的粗糙度最大，农田防护林的粗糙度较小，片林的粗糙度比林内道路提高了1.65倍，比裸地提高了4.81倍；农田防护林带阻沙作用主要在林带背风面，占总阻沙量的82.3%，而杨树片林的阻沙作用主要在林内，占总阻沙量的87.1%。平均阻沙量片林>林带防护林。
Abstract:
Based on the observations and investigations, the paper studies the rule of preventing sand blown by wind of two types of artificial vegetation, in Yanqing county.The result shows that: wind speed of forest belt descends most and the efficiency of wind prevention is best behind 7H from windward side; The one of patch forest is behind 9H from windward side.The roughness of patch forest is 1.65 times larger than road in forest, and 4.81 times larger than bare area.the effect of sand prevention in forest belt is primarily behind the leeward side, with the protective ratio of 82.3%, and the patch forest is inner of forest, with the protective ratio of 87.1%.The order of the average quantity of sand prevention are patch forest>forest belt.
