摘    要:以苏锡常地区具有典型性的原锡山市不同土地利用类型和不同时间的土壤取样点为研究对象,从时空转换角度分析土地利用变化对土壤质量的影响.结果表明,1980-1995年,苏锡常地区土地利用结构变动速率为0.59;1995-2000年,苏锡常地区土地利用结构变动速率增加为0.74.统计分析和独立样本t检验结果表明:1982-2005年原锡山市pH降低0.58,w(有机质)降低1.02 g/kg,w(全氮)降低0.16 g/kg,w(全磷)降低0.48 g/kg,w(速效氮)降低7.63 mg/kg,w(速效磷)增加26.16 mg/kg,w(速效钾)增加36.9 mg/kg,土壤含水率降低0.52%,土壤的相对质量指数降低3.06;在不同土地利用方式下,土壤质量各指标的变化具有明显的差异性.

Abstract:Different land use types and soil sampling sites of different time were studied in former Xishan City, a typical area of Suzhou-Wuxi-Changzhou region in South Jiangsu, to analyze the influence of land use changes on soil quality from the viewpoint of the change of time and space. The results showed that the land use change rate was 0.59 from 1980 to 1995, and the rate increased slightlyto 0.74 from 1995 to 2000. Through statistical analysis and independent-samples t test, it is indicated that, from 1982 to 2005, the soil quality of former Xishan Citychanged significantly: The pH value decreased by 0.58, organic matter by 1.02g/kg, total nitrogen by 0.16 g/kg, total phosphorus by 0.48 g/kg, andavailable nitrogen by 7.63 mg/kg, while available phosphorus increased by 26.16 mg/kg, available kalium by 36.9 mg/kg, and water by 0.52%, respectively. Relative Soil Quality Index (RSQI) decreased by 3.06. The land use and land cover change play an important role in the deterioration of this region.
Keywords:land use change  soil properties  Suzhou-Wuxi-Changzhou region (SXC region)  former Xishan City
