【摘要】 研究了克拉玛依市区北郊人工生态防护林地及相邻荒漠区的土壤养分及盐分,结果表明:人工生态防护林土壤养分较荒漠区有明显提高,尤其是土壤 N 素含量增加显著;有机质及速效养分主要集中在土壤表层,且随着土层深度的增加,人工生态防护林的培肥作用减弱;土壤 pH 值趋向中性;主要离子组成更加集中;可溶性盐主要集中在40～60 cm 深度。更多还原

【Abstract】 The effects of the shelterbelt system on soil characteristics are evaluated in peri-urban Karamay. The emphasis in this paper is to measure the soil nutrients and salinity properties between artificial shelter- belt and desert zone.The results indicate that the soil nutrients at artificial shelterbelt are improved notice- ably than the one of desert zone,especially nitrogen matter content of the soil.Organic matter and available soil nutrients are mainly at the surface of the soil,and along with the increasing of soil depth,the fertiliza- tion role weakened.The soil pH tends to neutral.Main ion composition becomes more focused.Soluble salts mainly concentrated in the 40～60 cm depth.更多还原
