摘要
构建"压力—状态—响应"(PSR)模型,结合SPSS 19.0软件,采用主成分分析法对2005~2014年广西城市土地集约利用水平进行评价,得出土地利用的协调度。结果表明:2005~2014年广西城市土地集约利用水平有显著的提高,提高幅度约110%,各准则层间的协调度高,但是压力(P)模型波动较大,主要原因是人口和建设用地的增长给土地利用带来了很大的压力。根据结果分析,对土地集约利用评价提供了对策建议。
Constructing PSR (Pressure-State-Response) model, combined with the SPSS 19.0 to evaluate the intensive utilization of urban land in Guangxi from 2005 to 2014, using the principle component analysis, and obtained the land use coordination degree. The results showed that the land intensive use in Guangxi was significantly improved during 2005 to 2014, the amplitude is about 110%, the coordination between the various standards is high, but the pressure model (P) fluctuated greatly main because the growth of population and construction land has brought great pressure on land use. This paper gives countermeasure suggestions to the land intensive use according to the results.
