双台子河口“红海滩”退化初探

Suaeda Heteroptera Degradation in the Estuary of Shuangtaizi River

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10gkg^-1～16gkg^-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 relationship between Suaeda heteroptera and soil salt was studied to explore the reason for the degradation of Suaeda pterantha in the estuary of Shuangtaizi River, based on the sea water monitoring, field survey and pot experiments. The results showed that： the content of soil salt between 10g kg^-1 and 16g kg ^-1 was the critical level for the growth of Suaeda heteroptera. The increase of soil salt content was the main reason that resulting in the degradation and death of Suaeda heteroptera in the estuary of Shuangtaizi River.
