Abstract: By employing DEA evaluation model, this paper inspects and measures the land use efficiency and its improvement in Poyang Lake Eco-economic Zone in 2011 from the new perspective of low carbon and intensification. The results show that under the guidance of the concept of harmonious development of ecology and economy, the efficiency of low-carbon and intensified land use in Poyang Lake Eco-economic Zone is on the whole rather satisfactory, and most counties (cities and districts) within the zone have paid equal attention to the intensified use and low-carbon use of the land resources. However, the input in regional land area, total highway mileage and social employment has a higher level of redundancy; such issues as regional GDP, the main business income of the high and new technology industry, and insufficient gross output of the qualified construction enterprises are rather prominent; the efficiency of low-carbon and intensified land use in Poyang Lake Eco-economic Zone still has a large room for improvement. Therefore, this paper puts forward the following suggestions: in accordance with the regional function location requirements, the structure optimization of land use should be combined with the adjustment of industrial structure, the scale of land use and the factor input should be reasonably planned, the low-carbon economic development mode should be promoted, and the method of land exploitation and utilization should be pushed to change from extensive mode to low-carbon and intensified mode.

Key words: Poyang Lake Eco-economic Zone; land use efficiency; low-carbon and intensification
