| 中文摘要: |
| 为探究不同乡土树种造林模式对土壤理化性质的影响,以乌兰察布地区不同乡土树种造林模
式为研究对象,对不同造林模式下林地土壤理化性质进行综合分析,利用主成分分析的方法对各造林模式下土壤理化性质进行综合评价。结果显示,不同造林模式均不同程度改善了土壤物理性质,
其中山杏柠条锦鸡儿块状造林模式土壤的持水性指标及总孔隙度指标最高;不同造林模式均改善了土壤的pH、全效养分含量,全磷含量在表层土壤均显著高于对照,沙棘柠条锦鸡儿行间造林模式
土壤全氮含量、有机质含量显著高于山杏纯林模式;相较于对照CK不同造林模式均显著提高了土壤速效磷、速效钾含量;所有造林模式综合评价得分均高于对照CK,其中山杏柠条锦鸡儿块状造林模式综合得分最高,建议在林业生态建设及修复中可应用该模式开展人工造林。 |
| 英文摘要: |
| To explore the impact of different native tree species afforestation patterns on soil physical and
chemical properties, taking the afforestation models of different native tree species in Ulanqab region as
the research object, the soil physical and chemical properties of different afforestation models were comprehensively
analyzed and evaluated by principal component analysis. The results showed that different
afforestation modes improved soil physical properties to varying degrees, among which the soil water holding
capacity index and total porosity index were the highest in the block afforestation mode of Armeniaca sibirica and Caragana korshinskii; different afforestation modes improved the pH and total nutrient content
of the soil, and the total phosphorus content in the surface soil was significantly higher than the control,
and the soil total nitrogen and organic matter content in inter row afforestation mode of Hippophae rhamnoides
and Caragana korshinskii were significantly higher than the pure Armeniaca sibirica forest mode;
compared with the control CK, different afforestation modes significantly increased the content of soil available
phosphorus and available potassium; the comprehensive evaluation scores of all afforestation
modes were higher than the control CK, among which the block afforestation mode of Armeniaca sibirica
and Caragana korshinskii had the highest comprehensive score, therefore this mode could be applied to
carry out artificial afforestation in forestry ecological construction and restoration. |
