基于PSR模型的区域土地利用可持续性分析——以山东省济南市为例

Analysis on Regional Land Use Sustainability Based on PSR Model——aking Ji'nan City in Shandong Province as an Example

山东省济南市是我国中部地区最为重要的城市之一。近年来,随着经济的不断发展,济南市土地可持续性利用问题成为了学术界研究的热点之一。该文主要运用了PSR模型,从压力-状态-响应3个方面选取了9个指标,构建了土地利用可持续性评价指标体系及模型,对山东省济南市进行了评价。研究结果表明,济南市土地利用可持续性整体上有了一定的提高,在未来发展中,济南市要始终注重耕地保护,用养结合,提高土地的可持续利用程度。

Ji＇nan is one of the most important cities in the central region of China. With the continuous economic development in recent years, the problem of sustainable land use in Ji＇nan has become one of the hot spots in the academic field. According to the characteristics of sustainable land use, we selected nine indicators from three as- pects including pressure, state, response, and established land use sustainability evaluation index system and com- prehensive evaluation model in Jinan city. It is showed that land use sustainability of Ji＇nan city has been improved in recent years, but the situation is still not optimistic. In the future, Jinan should continue to implement the most stringent farmland protection policy, increase the intensity of environmental protection, and avoid the land sustain- able utilization level decline in the rebound.
