宁南山区退耕地不同植被恢复方式下土壤理化特征研究
Study on Soil Physical and Chemical Characteirstics under Different Vegetation Restoration Measures in t he Degenerated Farmland of Southern Ningxia Mountainous Region
摘要
Abstract
Objective] The aim was to discuss effects of different vegetation restoration measures on soil physical and chemical properties in Southern Ningxia mountainous area.[Method] Soil physical and chemical properties under 3 restoration measures(natural restoration, artificial+natural restoration, sloping farmland) in typical region in Southern Ningxia mountainous area were determined and analyzed.[Result] The re-sults showed that soil moisture, soil porosity, organic matter, total nitrogen, total potassium content of natural restoration were 11.39%, 55.84%, 15.90, 1.03, 20.6 g/kg, respectively, which were higher than those of artificial+natural restoration and sloping farmland.[Conclu-sion] Comprehensive analysis showed that natural restoration is the effective action for restoring the vegetation in the Southern Ningxia mountain-ous region.关键词
