摘要：

采用地理信息系统(GIS)技术和地统计学方法,研究了湖北省恩施市“清江源”现代烟草农业科技园区、恩施城郊和利川柏杨基地单元新整治区域的土壤属性和速效养分空间变异特征,并采用模糊数学法对其土壤肥力适宜性指数(SFI)进行评价.结果表明: 土地整治对土壤速效磷含量的变异和空间分布的影响较大,这种影响程度可能与地形地貌特征和整治程度有关;土地整治对土壤pH值的影响较小,但是柏杨土壤酸化严重(pH<5.5).77.6%的城郊土壤具有较低的SFI,而柏杨和清江源分别仅有17.1%和31.4%的土壤具有较低的SFI.柏杨需要重点解决土壤酸化问题,城郊需要重点解决整个区域土壤培肥和肥力均衡化问题,而清江源则需解决SFI较低区域的培肥问题.

Abstract: By using geographic information system technology (GIS) and geostatistics methods, this paper studied the spatial variability of soil properties and available nutrients in the new regulation area units located in Qingjiangyuan modern tobacco agriculture science and technology park (Enshi, Hubei), suburb of Enshi City and the Baiyang base of Lichuan City, and further evaluation of the soil fertility suitability index (SFI) was carried out by use fuzzy mathematics. The results indicated that the effects of land restoration on the soil available phosphorus content variability and spatial distribution were very obvious, possibly due to the landform characteristics and restoration extent. The effect of land restoration on soil pH was small, however, serious soil acidification was detected in the soil sampled from Baiyang (pH<5.5). Low SFI was found in 77.6%, 17.1% and 31.4% of the soils taken from the suburb, Baiyang and Qingjiangyuan, respectively. In conclusion, attentions should be paid on soil acidification in Baiyang, soil fertility and equalization in the suburb, and soil fertility in the region of Qingjiangyuan with low SFI.
