Abstract:
The climatic characteristics and the dustproof effect of agroforestry ecosystem are studied in Raoyang County, Hebei Province. The results shows that:(1) In sandy soil area, the dynamic and hydrological effect of the agroforestry system are remarkable, and it is the directive reason for reducing the falling the dust capacity. (2) The stronger the wind-protection ability is, the better the dustproof effect will be. Agroforestry system could reduce the transporting dust capacity effectively, and reduce the falling dust capacity by 20%~60%. (3) Wind-protection effect, turbulivity and soil moisture are the main factor which determine the falling dust capacity.
Key words: Agroforestry system, Wind-protection effect, Falling dust
