Abstract
Land is not only a major space for human production and living, but also one of the most precious resources to humans. As a space carrier of urban construction, urban land resources constitute the part with the highest asset benefit among land resources, offering an essential space for economic reproduction, population reproduction and environment reproduction in urban areas. To sum up, urban land resources are the material basis, guaranteeing sustainability of urban development.In this paper, changes of sustainability of land use in Zhengzhou City, Henan Province from 2011 to 2015 were analyzed so as to evaluate sustainability level of land use in Zhengzhou. Based on correlation analysis, resource, environment, economy and society were selected as four evaluation indexes, and their weights were determined. Then, the method of maximum was used to realize data normalization, and the comprehensive index value was computed. Finally, sustainability of Zhengzhou’s land use was comprehensively evaluated. Taken as a whole, sustainability of Zhengzhou’s land use was improving from 2011 to 2015, but the comprehensive sustainability level was still low, calling for further strengthening. From 2014 to 2015, the sustainability level of land use was still on the downward.

Summary
With explosive growth of population and economy, the environmental pressure is increasing, among which land degradation has drawn worldwide attention, driving scholars to study it from different perspectives. Correlation analysis was employed to evaluate land use of Zhengzhou from 2011 to 2015. Emergence of Central Plains is to realize comprehensive and sustainable development of central plains, and sustainable development of Henan Province rests on sustainable development of local resources, environment, economy and society. As the provincial capital of Henan, Zhengzhou has gradually realized the importance of sustainable land use. Impacted by both natural factors and human factors, such as growing population pressure, low economic development, and unreasonable development, Zhengzhou’s land use sustainability still calls for improvement
