Abstract:

The dust fall and forest soil of Pinus sylvestris var.mongolica plantation in the southern Horqin sandy land from 2020 to 2021 were collected and analyzed.The results showed that Pinus sylvestris var.mongolica plantation could play a good role in reducing sand and dust weather,and there was a significant negative correlation between particle deposition and distance from forest edge (P<0.05).The closer to the forest center,the lower the sand content of dust fall would be,and the higher the organic matter and total nitrogen content would be.Affected by dust fall,forest soil nutrients were significantly positively correlated with the distance from the forest edge (P<0.05).The farther from the forest edge,the higher the content of soil organic matter and total nitrogen would be.Pinus sylvestris var.mongolica plantation has played a good role in reducing sand dust and improving soil fertility in Horqin sandy land.

Key words: Horqin sandy land, dust fall, Pinus sylvestris plantation, organic matter, total nitrogen
