基于灰色关联分析的砒砂岩区不同林龄沙棘的改土效应
|
摘要
[目的]探究不同林龄沙棘对其下土壤的改良效果,为砒砂岩区人工沙棘林生态建设、恢复和重建提供理论依据。[方法]以内蒙古达拉特旗典型砒砂岩区不同林龄沙棘林为研究对象,利用灰色度关联分析法,对沟坡阳坡1～7 a沙棘林0—40 cm土层土壤物理性质(土壤含水量、土壤容重、土壤总孔隙度、土壤比重、土壤毛管孔隙度、土壤非毛管孔隙度、土壤饱和持水量、土壤最大毛管持水量)进行测定,并以周边荒坡作为对照(CK),对不同林龄沙棘林对砒砂岩土壤的改土效应进行分析。[结果]土壤含水量、土壤总孔隙度随沙棘林龄增加而增大,随土壤深度增加而减少,土壤容重与之相反;不同林龄沙棘能增强土壤持水能力,并且4～7 a沙棘持水能力大于1～3 a沙棘持水能力。[结论]在砒砂岩区营建人工沙棘林有利于土壤改良,不同林龄沙棘对土壤改良作用主要作用于0—10 cm和10—20 cm土层。
[Objective] The effects of artificial Hippophae rhamnoides forests on soil quality improvement under different ages were studied in order to provide a basis for scientific evaluating ecological construction, restoration and reconstruction of Artificial Hippophae rhamnoides forest in sandstone area. [Methods] Taking the Hippophae rhamnoides forests of different ages in typical sandstone area of Dalat Banner of Inner Mongolia as the research object, and using the gray correlation analysis, the soil physical properties(soil water content, soil bulk density, total soil porosity, specific gravity of soil, soil capillary porosity, soil non-capillary porosity, soil saturated water holding capacity and soil maximum capillary water holding capacity) of 0—40 cm soil layer of Hippophae rhamnoides forest from 1 a to 7 a on the sunny slope of the slope were measured. The soil improvement effect of Hippophae rhamnoides forests on sandstone soil under different forest ages was analyzed with surrounding barren slope as control(CK). [Results] Soil water content and total soil porosity increased with the age of Hippophae rhamnoides forests, decreased with soil depth, but soil bulk density was opposite; Hippophaer hamnoides of different forestages could enhance soil water holding capacity, and the water holding capacity of Hippophae rhamnoides of 4～7 a was greater than that of Hippophae rhamnoides of 1～3 a. [Conclusion] The construction of artificial seabuckthorn forest in sandstone area is beneficial to soil improvement. Hippophaer hamnoides of different forestages mainly affected soil improvement in layers of 0—10 cm and 10—20 cm.
