摘要: 在滨海盐碱地区开展植树造林是改良盐渍土壤的重要手段。对黄河三角洲4个人工林及对照空地的土壤理化性质指标及其相关性进行测定和分析,并运用因子分析法对不同人工林的土壤改良效果进行综合评价。研究结果表明:1)4种人工林均能改善黄河三角洲滨海盐碱地的土壤质量,降低土壤容重、含盐量,增加有机质及速效养分含量,且各理化指标之间存在一定的相关性;2)因子分析结果显示,不同人工林土壤质量综合评价得分情况为:白蜡(1.223)>杜梨(0.686)>柽柳(0.307) >盐柳(-0.107)>空地(-2.108)。

Abstract: Afforestation is an important way to improve soil condition in coastal saline land.?In order to study the soil improvement effects of different plantations in coastal saline land of the Yellow River delta, we analyzed the soil physiochemical properties and their correlation of four different plantations and the control of the unplanted land. Also, the factor analysis was used to evaluate the soil improvement effects of four different plantations. The results showed that:1) The four different plantations could improve the soil physiochemical properties in coastal saline land of the Yellow River delta, reduce the soil bulk density and salinity, and increase the contents of organic matter and available nutrients. Moreover, there was a certain correlation between the physiochemical indicators.2) The result of factor analysis showed that soil improvement effects of different plantations was obtained in the following order: Fraxinuschinensis (1.223) > Pyrus betulifolia (0.686) > Tamarix chinensis (0.307) > Salix psammophila ‘YanliuYihao’ (-0.107) > CK (-2.108).
