The Study On Vegetation Restoration Of The Conveyor Field And Environmental Perception Of Sihe Coal Mine

Mineral resources of China are so rich.The development and utilization of it bring much economic benefits.But at the same time,the caused environment and social problems has been focused widely.In this article,the effect of vegetation restorations of soil properties was discussed through field trips and indoor experiment and the effect of resident attribute of environmental perception was investigated.On this basis,the best vegetation restoration was found which could provide the reference to conveyor field management.And the advantages and disadvantages of development of coal mine though the evaluation of resistant was found which could guide the future sustainable development orderly and efficiently.The main conclusions show that:(1)There was a good improvement of different vegetation restoration to soil properties.The improvement of the tree of heaven model was the best to soil pH value and the value after restoration was 7.73.At the same time,the pH value in deep soil was higher than the top soil.The improvement of locust tree model was the best to soil organic matter and the maximum was 1.79 times of the control.The pH value in top soil was higher than the deep.(2)The content of four heavy metal element was below the national secondary standard.The content of Pb and Cr has the higher value than Shanxi background value.Among them,the maximum absorption of Zn was shrub model.The maximum absorption of Cu was the tree of heaven model.And the model of locust tree and tree of heaven has the most obvious purification effect of Pb and Cr.(3)Among the six environment problems of the coal mine,residents was satisfied with the management of conveyor filed and vegetation greening.And the coal mine health and noise pollution was the unsatisfactory.The air quality and the water quality were the second.The effect of residents attribute to environmental perception has big differences.The age of conveyor filed management and noise pollution was the biggest.The effect of live time of vegetation greening was the biggest.Female has highest perception degree of the air quality,the water quality,noise pollution and conveyor filed management.And the workers of coal mine,farmer,and retired residents that with different professional attribute has highest perception degree of the air quality,the water quality,noise pollution,vegetation greening and conveyor filed management.So,vegetation restoration of Sihe coal mine has made great development.The soil quality and environment problems had been improved.The tree of heaven model has the best improvement to soil properties and the heavy mental.The satisfaction of all the residents keeps improving.
