渤海湾泥质海岸地带部分生态因子的研究

通过对黄骅港经济开发区地下水、土壤以及沙尘等自然因子的研究表明:临海地带的地下水位浅,水含盐量在0.5%以上;土壤含盐量一般在0.6%以上,土壤孔隙度小,容量大,土壤有机质和速效氮明显低于正常耕田土;沙尘中含盐量在0.20%～0.32%.带有一定的含盐物质.这些生态因子是制约渤海湾泥质海岸地带绿化苗木正常生长的重要因素.

Study on Partial Ecological Factors of Bohai Bay Muddy Coast

Ecological factors of groundwater,soil and dust at Huanghua Port Economic Development Zone were researched, the results showed that water table of coastal zone was shallow, water salinity was above 0.5 %, soil salinity was usually above 0.6% ,Soil porosity was small,soil bulk density was large, soil organic matter content and available N were Obviously below the normal cultured soil. The salinity of dust was 0.20% -0.32%, dust contained many salts. The ecological factors were in restraint of the growth of green seedlings.
