摘要: 为了探究防护林对不同地貌类型耕地的影响,选择科尔沁沙地奈曼旗境内坨耕地和甸耕地,对比分析了在有、无防护林情况下坨耕地和甸耕地土壤理化性质及其变化特征。结果表明:① 有防护林耕地土壤理化性质优于无防护林耕地;② 防护林对坨耕地的影响大于甸耕地,其影响在样点1、样点2和样点3都有显现,且在样点1和样点2较为突出,而防护林对甸耕地的影响只在样点1较为明显。

Abstract: In order to explore the effects of shelter forest on farmland in different landforms, in this study the lump farmland and meadow farmland in Naiman Banner in the Horqin Sand Land were selected to carry out a comparative analysis on soil physicochemical properties of the farmland with or without shelter forest. The results were as follows: (1) Soil physicochemical properties of farmland with shelter forest were better than those of farmland without shelter forest; (2) The effect of shelter forest on lump farmland was higher than that on meadow farmland, it was obvious at all the three sample plots of lump farmland, especially at sample plot 1 and sample plot 2, but the effect of shelter forest on meadow farmland was obvious at sample plot 1 only.

Key words: shelter forest, landform, lump farmland, meadow farmland, soil physicochemical property, Naiman Banner, Horqin Sand Land
