Performance evaluation of Changzhou's new energy industry can provide reference for constructing diversified investing channels and improving industrial policies. This paper, based on Changzhou's background and situation of new energy industries, uses input/output data of new energy industries in 2008 and 2009, DEA model and DEAP2.1 software to analyze the performance, which has been proven well. In addition, it is suggested that the performance of new energy industry in Changzhou should be improved by such methods as stipulating industrial development program, establishing the service system of technology innovation, improving financial systems and setting up industrial bases.

To adjust the basic farmland layout according to “area not decreased, quality increased, layout stabilized” principle is a big part in the new land use planning. This paper, based on the ideas of stabilizing the current basic farmland layout, studies the ways to adjust the basic farmland layout. An index system which covers farmland quality, locality, slope and integrity is established to evaluate the potentials. Based on a case study on Gao'an city, Jiangxi province, a comprehensive method is used to evaluate the potentials via GIS, which is employed to adjust the basic farmland layout. After adjustment, the excellent farmland percentage rises form 38.35% to 45.35%, integrity percentage from 27.81% to 30.56%. This study optimizes the basic farmland layout, offering references in adjusting the basic farmland layout in a countylevel land use planning.

This paper, according to land utilization change survey during 1998 to 2004, applies land utilization dynamic model and land utilization comprehensive index model analyzes quantitatively the land utilization change, and studies the induced ecological service value with the results indicating an outstanding change in land utilization structure, which means an increasing land utilization extent followed by a decreasing ecological service value. This paper suggests that a sustainable development of land utilization in Jingzhou shall be based on high land utilization efficiency and a good ecological environment.
