Abstract: Nowadays the global ecological and environmental problems have become increasingly prominent. Land deterioration seriously restricts the regional development of society and economy and threats to the survival of humans. We carried out a series of experiments on ecological restoration of melilotus offcinalia in various types of environment like strong saline-alkali land, barren land and mine land for the first time. The comparison of soil indexes between restoration soil and background soil shows that melilotus offcinalia can removal off salinity and base of the strong saline-alkali soil and increase the nutrient contents in various types of soil. Moreover, melilotus offcinalia can improve physical properties of soil, which will increase the land coverage and improve land productivity. Consequently, melilotus offcinalia can be promoted in stages for soil amelioration and ecological restoration in various types of ecological environment.

Abstract: Transportation industry is an important field to reduce greenhouse gas emissions and climate change. Scenario analysis of transportation industry can provide theoretical support to the formulation and implementation of carbon emissions reduction policy. In view of this, The transportation industry of Jiangxi province will be given into four departments including civil aviation, railways, highways and waterways, and it was used the LEAP model to set three scenarios in the different application of economic development mode and different traffic development mode, then forecasted the main carbon emissions of Jiangxi transportation industry in 2010-2030, and analyzed the result of forecasting. It shown that the way to ease the nervous energy supply and the pressure of carbon emissions, and achieve the sustainable development of energy and the environment, must be set the four departments of reasonable transportation distribution under the condition of different energy sources, and increase the scope of using the new energy and renewable energy.
