بررسی تعیین مشخصات خاک درارتباط با جوامع گیاهی در قسمتی از جنگلهای منطقه واز (زیر حوزه 1و2) در منطقه مازندران

The aim of the study was to investigate soil properties in relation to forest typs and plant communities at Vas Experimental Forest at Caspian region of Iran (Mazandaran province). The research reports of Amini and Khaleghi was used in this study, particolary the site characteristics. Soil sampling was made from S8 profiles where 24 typical profiles were interodiuced in this final report. The measured soil properties were: bulk density, texture, organic matters, Anions, Cations and CIN. The results show that soil depth of the most profiles was low and not desirable for the trees. The soils had light texture (loamy silt). Furthennore, the soils were poor in nutrition and organic metter (CIN< 15). Doe to low organic matter, undesirable texture and other properties, the soils of Vaz Forest are under degradiation. Key words: Anions, bulk density, catios, C/N, organic matter, texture.
