摘要:

收集2020—2021年科尔沁沙地南部樟子松人工林内的降尘和森林土壤进行研究分析。结果表明,樟子松人工林对沙尘天气能起到良好的消减沙尘作用,颗粒物沉降量与离林缘距离呈显著负相关(P<0.05)。且距离林分中心越近,尘降的沙粒含量越低,其有机质和全氮含量越高。受降尘影响,森林土壤养分与离林缘距离呈显著正相关(P<0.05),距离林缘越远,土壤有机质和全氮含量越高。樟子松人工林对科尔沁沙地起到了消减沙尘、培肥地力的良好作用。

关键词: 科尔沁沙地, 尘降, 樟子松人工林, 有机质, 全氮

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
