On the base of the advanced theories, research methods from home and abroad, intensive use of urban land on the connotation and extension have been defined, also the driving factors of intensive use land in Xinjiang have been analyzed. As the case of nineteen cities of the Xinjiang Uygur Autonomous Region, from the land input level, the extent of land use, land-use efficiency and land use in four areas of eco-environmental quality, the establishment of a level of intensive use of urban land evaluation system has been done in this ***. Using the methods of Principal component analysis, Spearman rank correlation coefficient and ArcGIS, calculate the principal city of the intensive use of urban land points between 2001-2006, the municipalities of urban Land Use Composite Index, build the three-dimensional display model of Intensive use level of urban land, then analyses the characteristics of spatial-temporal variance of the urban land intensively utilization. Finally, analysis propose measures and advices.

The effects of compositions on UV prinking ink,such as prepolymer,monomer,photoinitiator and pigment on curing rate,cohesive force,resistency and other properties were investigated. The range analysis and variance analysis method were applied to the assessment of results. The results based on orthogonal experiment design indicated that an optimum component composition of UV printing ink can be obtained from prepolymer PQ611,monomer A,photoinitiator B and active amime.
