摘要
通过实地调查，汇集１５０位专家对“三北”盐碱地宜林性评价结果的有关资料，运用模糊综合评判方法排序和ＤＥＡ方法优选，评选出“三北”地区５个不同自然区（黑龙江片：黑龙江大部，内蒙古东北部，吉林北部；吉、蒙片：内蒙古东部，吉林西部；京、津、辽片：北京，天津，辽宁西部，河北北部；青、甘、蒙片：青海北部，甘肃大部，宁夏全部，陕西北部，内蒙古中西部；新疆片：新疆全部）盐渍化（轻、中、重）土地的适宜树种，并进行了“三北”地区盐碱地分类和宜林评价，为“三北”防护林地区盐碱地造林提供科学依据。
The quantitative process of suitable plantation evaluation of saline land in northern shelterbelt area has been adopted. (1) To collect related test data,(2) investigation in northern shelterbelt area,(3)method of expert evaluation remark,and through fuzzy multifactor decision ordering and DEA optimization,could be used to estimate the salt tolerance tree species in the area with different salinity (light,medium,heavy),different tree species (tree,shrub,economic forest),different suitability (suitable,assistance,reference) and 5 different nature areas (Helongjing nature area,Beijing Tianjin Liaoning nature area,Jilin Inner Mongolia nature area,Qinghei Gansu Inner Mongolia nature area,and Xinjinag nature area). The results showed the saline soil classification project and suitable plantation evaluation of saline land.
