摘　　要：为探讨盐碱地治理利用方向,针对山东省典型地区,利用遥感影像及变更调查资料,分析研究了典型地区盐碱地分布现状,介绍了“上农下渔”、暗管排盐两种治理模式,结合高程、坡度、土壤类型、土壤侵蚀数据,进一步研究其空间分布和结构变化。以不同治理模式下东营市河口区10个土壤理化性质改良指标作为数据来源,采用主成分分析法对三个深度的四组治理模式进行动态监测和综合评价,结果表明两种治理方式均能够改善土壤理化性质,达到较好的治理效果。在此基础上,针对盐碱地与其它土地利用类型转换情况和变化趋势进行分析,重点阐述了盐碱地开发利用为耕地后潜在经济社会效益。最后针对生态文明建设要求下盐碱地开发治理提出了相关建议。In order to explore the management direction of the typical saline-alkali land in Shandong province,this paper firstly analyzed the current spatial distribution situation of the typical saline-alkali land area,by utilizing the remote sensing images and survey data.Then two management modes,i.e.,"Agriculture(top)-fishery(bottom)"and salt drainage by hidden pipes are introduced.Combined with the elevation,slope,soil type,and soil erosion data,the spatial distribution and structure change are further studied.Specially,this paper takes ten properties as the improvement indexes to measure the effect of different management modes for Hekou District,Dongying city,where the principal component analysis(PCA)was used to dynamically monitor and comprehensively evaluate the four governance modes combination from three aspects.The results showed that the two governance modes could improve the soil physical and chemical properties and achieve better management effects.On this basis,the paper analyzed the conversion situation and changing trend of saline-alkali land and other types of land,and expounds the potential economic and social benefits after the development and utilization of saline-alkali land into arable land.Finally,the paper puts forward some suggestions on the development and governance of saline-alkali land under the requirement of ecological civilization construction.
