Investigation of dust effects resulting from cement industries on variation and density of rangeland vegetation cover Case study: Abyek cement factory

Contaminants resulting from cement industry include dust, C compounds, sulfur oxides and nitrogen oxides. Through the mentioned materials dust is more important Than the other Pollutant As itʹs high production and emission in the environment. In this research the effects of dust resulting from Abyek Cement Factory on diversity and density of rangeland vegetation cover were studied. Types and amounts of soil elements, variation and density of rangeland vegetation and amount of cement sedimentation on plants organs in variou s distances and aspects were investigated. The results of analy sis of soil samples elements, amount o f dust sedimentation on vegetation organs and assessment of vegetation cover density show that there is an inverted correlation between variation and density of vegetation cover and dust sedimentation exiting from factor smokes tacks . Sedimentation amount is reduced as much as we get far away from emission resource. The sed imentation amount is more and vegetation cover vari ation is less in the factor surroundings. In this area some resistant specie s such ac Artemisia sp and Ro sa sp are replaced
