摘要：

以植被恢复土壤效果评价7种人工植被恢复模式，应用灰色关联模型和聚类分析方法研究渭北旱塬区植被恢复对土壤综合质量的影响，以确定最优植被恢复模式。结果表明：不同人工植被恢复模式对土壤质量有很大影响，与对照（农地）相比，恢复年限为5年、10年紫花苜蓿（Medicago sativa）草地和恢复年限为30年刺槐（Robinia pseudoacacia）林地均提高了土壤质量，其中10年紫花苜蓿草地恢复效果最好。随着退耕还林还草工程的实施，在渭北旱塬区，种植牧草、建植乔木是较好的生态重建和植被恢复方式。

Abstract:

The effects of vegetation restoration on the comprehensive soil quality were investigated using grey correlation model and cluster analysis. Seven artificial patterns were evaluated and the optimum pattern was determined. The results showed that different artificial vegetation restoration patterns had different effects on soil quality. Compared to farmland, both Medicago sativapattern with 5-or 10-year and Robinia pseudoacaciapattern with 30-year could improve soil quality. The best pattern was Medicago sativapattern with 10-year. With the development of Conversion of Cropland to Forest and Grassland Project, both forage and tree planting should be the optimal choices to restore soil quality, as they could decrease the soil erosion and improve soil condition, especially in the arid area of northern Weihe river basin.

Key words: Arid area of northern Weihe river basin, Soil quality, Artificial vegetation restoration patterns, Grey correlation model, Cluster analysis
