Visualization of assessment course was achieved based on different land use functions with the help of ArcGIS9.0 and GIS layers with different properties were overlapped and computed with GIS grids. Hence, the areas were colored and reclassified（colors representing different ecological suitability degrees）. Finally, land use functions can be readjusted by the evaluation results,providing references for rational planning of economic development zones.展开更多

Meanwhile,to guarantee crop safety and stick to 0. 12 billion hm2of farmland red line as a rigid constraint which could not be exceeded,the supply-demand contradiction of industrial land is more and more prominent. With industrial land scale continues to enlarge,land resources become more and more scarce,but there exists the phenomenon of low-efficiency land use and even idle. For land use characteristics of the development zone,taking Hefei City Economic and Technological Development Zone as an example,the countermeasures of perfecting industrial land transfer mechanism in the development zone are proposed.展开更多
