In order to study soil recovery quality by using air sparging method, 13 days experiment is carried out in the field. Its is proved that adsorption type and residual type oil hydrocarbon in soil can contacted each other by using air sparging method, which can get rid of oil hydrocarbon through volatiliztion and aerobiont plants. It provides scientific basis for recovering plants polluted by oil.
Due to long-time exploitation of deep underground water in Decheng district of Dezhou city, large square of funnels have been formed, and surface collaspe have been formed as well. In order to protect geological environment and deep underground water resource in Dezhou city, artificial recharge experiment of deep underground water was carried out in 2002. Achievements of artificial recharge experiment is introduced in this paper, possibility, social and economic, environment efficacy have been analysed as well.
Geothermal resource in Dezhou city belongs to low-temperature type, wihich mainly occurs in cracks of Neogene and Paleogene sandstone. Geotherm in Dezhou city was explored and utilized in 1997, which develped very rapidly. Thus, its exploitation and protection have become an important subject in geological environment protection. According to geological condition and present exploitation and utilization condition of geothermal resource in Dezhou city, geological environment efficacy is analysed in this paper. On these basis, some suggestions are put forward as follows: resource and environment should be protected, exploitation and management of geothermal resource should be strengthened, development equipment should be renewed, artificial recharge experiment should be carried out and monitoring system and scientific system of geotherm utilization, exploitation and management should be established, etc.
Soil sandization not only destroies natural environment, but also effect human being′s living. Developing condition, damage degree and forming origin of soil sandization in old Yellow river channel in Xiajin county are analysed in this paper.
