以济宁市2010年复垦的引黄充填地块、引湖充填地块和预复垦地块为基础,研究在不同层次土壤颗粒组成、容重、土壤热通量的差异,探究三种复垦方式对耕地物理特性的影响。结果表明:(1)三种复垦方式改良层次分别为:引黄充填地块0~15cm,引湖充填地块30~50 cm,预复垦地块0~5 cm和15~30 cm。(2)引黄充填地块在0~30 cm范围内,土壤粉粒含量明显增加;引湖充填地块在0~15 cm粉粒含量低,15~50 cm粉粒含量有所增加,预复垦地块粗粉粒的含量较高。(3)在0~15 cm耕层,复垦地块土壤热通量与对照地块的相差程度由小到大依次为:引黄充填地块<预复垦地块<引湖充填地块。 Taking Jining Yellow River Reclamation Land Reclamation, Reclaimed Lake Reclamation Land and Reclaimed Land Reclaimed Land in 2010 as the base, the differences in soil particle composition, bulk density and soil heat flux at different levels were studied. Three kinds of reclamation The Impact of Ways on Cultivated Land Physical Characteristics. The results show that: (1) The improvement levels of the three reclamation ways are 0 ~ 15 cm for the Yellow River filling landfill, 30 ~ 50 cm for the filling lake and 0 ~ 5 cm and 15 ~ 30 cm for the pre-reclaimed land. (2) Within the range of 0-30 cm, the content of soil silt increased obviously. The content of silt in the lead lake was low at 0-15 cm and increased at 15-50 cm, The reclaimed land has a high content of coarse grains. (3) In 0 ~ 15 cm tillage, the differences of soil heat fluxes between reclaimed plots and the control plots are as follows: Yellow River fill land
