Research and Exploitation of Saline - Alkaline Plant Germplasm Resources and Salinity in Binzhou, Shandong
Abstract：Groundwater in most saline-alkali land is high salinity. Its level is high. Evaporation is greater than precipitation. Salt gets to surface with water and gathers. It promotes the formation of saline-alkali land. There is lots of saline-alkali land in northern Shandong region. They all have a high degree of salt. Because there are lots of plants which suitable for growing on saline-alkali land, it can be regarded as the model of saline-alkali land to study the exploitation of saline - alkaline plant. This topic focuses on the salt marshes in Binzhou, researching the soil composition and plants on it. We have got the soil salinity data and plant list. We have researched the connection between them and got the results.There are 42 species of salt-tolerance plants at Binzhou counted, belonging to 20 families 37 genera. Gramineae and chenopodiaceae is the largest most species.The main characteristic of saline-alkali land in Binzhou area is high salinity. Main soluble salt is Na+、Cl-.Plant species and population density change with soil salinity. For example, Suaeda and Suaeda salsa mainly grow in soil with high salt content.
Key words: saline-alkali land; Shandong region; salt-tolerant plant; soil analysis

1 引言
1.1研究现状
通过查阅相关文献资料，目前国外对盐碱地的研究主要集中在分子层面，例如：丛枝菌根真菌对盐碱地植物的影响、物理化学生物等方法应用于盐碱地的改良、植物耐盐机理的研究等。
国内大部分学者和研究机构也主要在分子层面进行微观研究，即使少部分进行宏观研究，也没有形成系统的数据库。
