    摘要:

    对溧水县33个土壤样点的阳离子交换量(CEC)进行了测定,应用地理信息系统软件将CEC点图在同一土壤类型中进行逆距离加权插值,叠加得到CEC空间分布图。溧水县土壤CEC平均值是12.50cmol/kg±3.56cmol/kg;空间分布图中有71.69%面积其土壤处于中等保肥供肥水平(CEC10~20cmol/kg)。在不同的地形中,CEC为5~10cmol/kg的土壤在低山的面积百分比大,占56.21%;CEC为10~20cmol/kg的土壤在平原的面积百分比大,占82.23%; CEC>20cmol/kg的土壤只在平原中出现,占0.30%。秦淮河圩区、石臼湖圩区、低山丘陵区的北区和西南区土壤CEC均在10~20cmol/kg,低山丘陵东区东庐山-马占山-关山-方山一线,土壤CEC为5~10cmol/kg。

    Abstract:

    A total of 33 soil samples were taken from Lishui County and analyzed, based on which a sample-point CEC map of the county was plotted out and turned into a CEC spatial distribution map through Inverse Distance Weighted interpolation and superposition with the aid of the GIS technology. Results showed that the soil CEC averaged at 12.50 ±3.56 cmol/kg over the county, and was at 10-20 cmol/kg in 71.69% of the spatial distribution map, and varied with topography, e.g. in low hill region, about 56.21% of the soil, mainly in the east part, was only 5-10 cmol/kg in CEC and in plain region, about 82.23% of the soil was 10-20 cmol/kg in CEC and only 0.30%>20 cmol/kg.
