中文摘要	通过实地调查与试验分析的方法,对赤峰市巴林右旗黄花林场撂荒沙化的栗钙土区栽植沙枣和榆树后土壤理化性质的变化进行了研究.结果表明:沙枣地和榆树地土层(h)0＜h≤15cm和15＜h≤30cm的土壤密度明显都低于对照撂荒地.沙枣地和榆树地土层(h)0＜h≤15cm和15＜h≤30cm的土壤孔隙度和持水量明显都高于对照撂荒地.沙枣地和榆树地土壤有机质和速效氮的质量分数都高于对照撂荒地,其中0＜h≤15cm土层内尤为明显.栽植沙枣和榆树可明显降低土壤密度,改善土壤孔隙状况,提高表层土壤有机质含量和速效氮含量,使土壤水、气、热状况得到改善,土壤肥力得到提高,并能够有效地防止土壤荒漠化的扩大.
英文摘要	An experiment was conducted to study the physical and chemical characteristics of desertification chestnut soil of a-bandoned arable land in Balinyouqi Huanghua Forest Farm of Chifeng City after planting Elaeagnus angustifolia and Ulmus pumila by field survey and experimental analysis. Results showed that the bulk densities in 0～15 cm and 15～30 cm soil layers in E. angustifolia and U. pumila stands were significantly lower than those of the abandoned farm land (control), while soil porosity, water holding capacity, organic matter content and available nitrogen mass fraction were higher than those of the abandoned farm land, especially in the 0～15 cm layer. It is obvious that E. angustifolia and U. pumila significantly reduce soil bulk density, improve soil porosity and increase contents of organic matter and available nitrogen in the surface soil, so it could improve the conditions of water, gas, heat in soil and soil fertility, and also effectively prevent desertification from expanding.
