相同郁闭度或覆盖度行带式配置的不同生活型植被的防风效能

Windbreak effect the same kind of canopy density or coverage belt scheme different life forms of vegetation

以郁闭度或覆盖度为20%左右的行带式乔木、灌木、半灌木防风林为研究对象,通过野外观测50cm高度处林内的风速。结果表明:相同风速下行带式配置的不同生活型植被林内的防风效能乔木>灌木>半灌木,行带式配置的同一生活型植被林内防风效能随着风速的提高而提高。

Taking forest coverage or coverage for about 20% of the line belt of trees, shrubs, semi-shrub windbreaks for the study,Through field observations 50 cm height wind speed within a forest. The results showed that: Same wind speed downlink belt configuration wind effects of different life forms within the forest vegetation,trees >shrubs >semi-shrub, Line with the same life-style configuration windbreak forest vegetation type effect increases with increasing wind speed.
