松嫩平原盐碱地研究存在的两个问题

Two Issues of Saline-Alkaline Research of Songnen Plain

论述松嫩平原盐碱化研究中存在的两个问题:①对松嫩平原盐碱化土地面积有多种不同的表达,且各种表达之间差异较大;②对松嫩平原盐碱化程度判别标准不尽一致。同时分析了出现这些问题的原因。笔者建议有关方面通力协作,规范松嫩平原土地盐碱化的判定标准,对当前松嫩平原盐碱化土地面积做出相对准确的分析和判断,为振兴东北工业基地、建立可持续发展环境提供科学决策依据。

Two issues are discussed about the saline-alkaline research of Songnen Plain. One is about the area ol saline-alkaline land in Songnen Plain, in which there are several expressions, the other is about the different indexes for the degree of salinization-alkalinization. Simultaneously, the causes of them are analyzed. Those two issues will misunderstand readers and have negative effect on the research for Songnen Plain. Therefore, it is necessary to regulate the indexes for the degree of salinization-alkalinization and figure out the area of saline-alkaline land in Songnen Plain by the good cooperation between all kinds of institutions.
