| 摘 要： | 土地盐渍化敏感性是指旱地灌溉土壤发生盐渍化的可能性。可根据地下水位来划分敏感区域,再采用蒸发量、降雨量、地下水矿化度与地形等因素划分敏感性级。从盐渍化单因子分析可知,在影响土地盐渍化敏感性的三个单因子中,有两个因子(蒸发量/降雨量、地下水矿化度)在全省平原区都为轻度敏感,只有地形因子略有差别,因此黑龙江省平原区土地盐渍化皆为轻度敏感。

| Abstract: | The sensitivity of soil salinization meant the probability of salinization of irrigation soil in dry land area.Generally,the sensitive area could be differentiated by groundwater level while the sensitive grade could be distinguished by factors such as evaporation,rainfall,groundwater salinity,terrain and so on.From the singal factor analysis of salinization we knew that the evaporation,rainfall and groundwater salinity in the plain area of whole Heilongjiang province belonged to slight sensitive level,whil... |
