盘锦“红海滩”退化初探

Desk study about the degeneration of red beach in Panjin

本文采用海水监测、翅碱蓬野外调查及盆栽试验和室内分析方法,研究了盘锦“红海滩”翅碱蓬群落的退化死亡原因,特别是翅碱蓬退化死亡与土壤盐分的关系。结果表明,翅碱蓬适宜生长的土壤盐分含量在10～16g/kg之间,初步认为由于滩涂土壤盐分升高产生的盐害是引起盘锦“红海滩”翅碱蓬群落退化死亡的主要原因。

Adopted some methods which were seawater monitoring, field investigation of seepweed, pot experiment and indoor analysis et al, researched the regressive reason and death reason about the seepweed community, especially the relation between the degeneration and soil salinity. The result indicated that the fitting soil salinity content of red beach was from 10 g/kg to 16 g/kg, it considered primarily that the main reason to cause the degeneration and death was the salt injury which was the high soil salinity of mudflat.
