| 摘要: |
| 为进一步研究鲁北平原(黄河以北)土壤盐渍化问题,采用二级模糊综合评判法,构造了隶属土壤环境条件、地下水环境条件和自然地理条件3个层面,盐渍土面积占比、土壤盐渍程度、土壤含盐量、包气带岩性、地下水位埋深、地下水矿化度、地形地貌与蒸降比8个指标的综合评价指标体系。将鲁北平原(黄河以北)盐渍化土壤环境质量划分为优等、良好、中等、较差和差5个等级。其中,盐渍化土壤环境质量差区面积5277.49km2,盐渍化土壤环境质量较差区面积6564.76 km2,盐渍化土壤环境质量中等区面积4383.79 km2,良好区面积5995.52 km2,盐渍化土壤环境质量优等区面积4919.29 km2。并针对不同的盐渍化环境质量条件,将土壤盐渍化的防治分区划分为3个防治区8个亚区,研究成果对促进鲁北平原农业农村经济的健康发展和社会主义新农村建设具有十分重要的意义。 |

| Abstract: |
| In order to further study the soil salinization in the northern Shandong Plain (north of Yellow River), two - level fuzzy comprehensive evaluation method is adopted. A comprehensive evaluation index system is constructed, which belongs to three levels of soil environmental conditions, groundwater environmental conditions and physical geographical conditions, and includes eight indexes: proportion of saline soil area, degree of soil salinity, content of soil salinity, lithology of aeration zone, depth of groundwater level, degree of groundwater salinity, topography and landform and evaporation ratio. The environmental quality of salinized soil in northern Shandong Plain (north of Yellow River) was divided into five grades: excellent, good, medium, poor and even poor. Among them, the area of even poor salinized soil environmental quality area is 5277.49km2, the area of poor salinized soil environmental quality area is 6564.76 km2, the area of medium salinized soil environmental quality area is 4383.79 km2, and the area of good salinized soil environmental quality area is 5995.52 km2. The area with excellent environmental quality of salinized soil is 4919.29 km2. According to the different environmental quality conditions of salinization, the prevention and control of soil salinization was divided into 3 prevention and control areas and 8 subareas. The research results are of great significance to promote the healthy development of agricultural and rural economy and the construction of new socialist countryside in northern Shandong Plain. |
