The oil and gas resources is an important lifeline of the national economy, and oil and gas exploration and development projects to create enormous social and economic benefits to the community at the same time, a certain amount of pollution and damage caused to the surrounding ecological environment for the development of oil and gas fields of the ecological environment is fragile areas construction to take more stringent measures of ecological protection. In this study, using a combination of field survey and remote sensing interpretation method, starting from the two key indicators of ecosystem of the soil and vegetation, and to carry out the impact of the ecological environment of the gas field development and ecological restoration measures, summarizes a comprehensive analysis of the gas field development project the species composition of the impact on the ecological environment in terms of soil, vegetation and land use, access to different restoration ages microphylla children planted communities, oil of Artemisia communities, natural recovery the shrub layer slice of the community biomass, individual density of herbaceous layer piece , biomass, species important values, species diversity and soil bulk density, soil total nitrogen, total phosphorus, total potassium, available nitrogen, available phosphorus, available potassium content of soil physical and chemical properties of indicators, comparative study of the different years of different recovery measures the ecological restoration of the effect of the coordinated development, the promotion of economic, social and ecological environment, as well as research and practical application of the gas field development zone of ecological restoration measures has important theoretical significance and practical value. In this study achieved major progress as follows: the eco-environmental impact of the gas field development is mainly an area for temporary and permanent. Well site, roads, gas gathering station, the construction of the pipeline and laying to change the existing land use patterns, changes the physical and chemical properties and structure of the original soil, difficult to restore the original soil structure and traits; vegetation mainly an area of ??destruction of vegetation and drilling waste pollution, leading to the decline in vegetation cover, biomass decline, reduction of biodiversity. Cause population growth with the restoration of years, the increase in the oil the Artemisia community and golden pheasant children community biomass, and the constructive species the individual density decreases, reveals the negative effects of excessive high density growth and development of the community there, space and resources, excessive competition, which is not conducive to the growth of vegetation. The species composition of the herbaceous layer films, important values ??and species diversity analysis showed that the herb layer is more than a biennial herb, with the restoration year growth, the diversity of the herbaceous layer are also species richness corresponding the improvement; same restore the life of the conditions, the species richness of the community in the herbaceous layer of planted microphylla children important values ??and diversity and so is relatively higher than the artificial cultivation of oil of Artemisia communities, both higher than natural recovery. With restoration age increased nutrients in the soil showed an increasing trend as a whole, in addition to available K, planted microphylla children community measures soil nutrients were higher than in the artificial cultivation of oil of Artemisia community; under the conditions of different restoration measures in the same recovery years, and both higher than the natural recovery community, soil restoration effect of planting the golden pheasant children community is significantly higher than other recovery. In general, the preferred sequence of the gas field development zone and the whole Mu Us sandy land restoration measures: of artificial planting microphylla children community gt; planted in oil Artemisia communities gt; natural recovery.
