This paper applies GREET model and WTW system to compare their energy consumption and pollution emission in a form of currency between the traditional petroleum and new energy vehicles (battery electrical, hybrid and fuel cell vehicles) during their entire life circles. On energy consumption, new energy vehicles save energy under similar energy structure and technical parameters. BEV is on the top in energy consumption with a decrease by 42% with the traditional petroleum vehicles. New energy vehicles chiefly contribute to carbon emission reduction, falling by 5.78% on hybrid, 32.86 on feul cell, and 21.54% on BEV compared to traditional, but with an increase by 35.36% on acid rain pollution emission. From the total costs, new energy vehicles are lower than the traditional except the BEV. Developing new energy vehicles, especially the BEV, is somewhat of more advantages than disadvantages, which may be improved as China's energy structure alters. 

This paper, based on China's land consolidation partition and methods, presents a partition plan for land consolidation, summarizes some typical modes of sustainable development in various areas, providing a reference for sustainable land consolidation in various areas.

RS and GIS are a helpful tool to measure the soil erosion, to quickly monitor the dynamic changes in soil erosion distribution and extent. This paper, based on a case study of the upstream of Fenhe Reservoir in Yellow River, applies the Remote Sensing data of Landsat MSS (1976), TM (1990) and ETM+ (2002) to dynamically monitor the land erosion with the results indicating that the soil has been eroded extensively during 1976 to 1990, and turned to a good condition in general during 1990 to 2002, but still worsening locally. It is a big task to maintain the water and soil.
