采用海水监测、翅碱蓬野外调查和盆栽试验方法,研究了双台子河口“红海滩”翅碱蓬群落退化原因,特别是翅碱蓬退化死亡与土壤盐分的关系。结果表明:翅碱蓬生长适宜的土壤盐分含量在10g kg-1~16g kg-1之间,初步认为由于滩涂土壤盐分升高产生盐害是引起双台子河口“红海滩”翅碱蓬群落退化死亡的主要原因。
The reasons for the degradation of Suaeda philippinarum community in Shuangtaizi Estuary, especially the relationship between the degradation of Suaeda salsa and the soil salinity, were studied using seawater monitoring, field investigation and pot experiment. The results showed that the optimum soil salt content was between 10g kg-1 and 16g kg-1, and the salt damage was the main cause of the degenerative death of Suaeda philippinarum community in Shuangtaizi Estuary .
