摘要
土地的有序利用是城市可持续发展的基础,土地资源的合理利用关系到社会经济和自然环境的发展。以湖北省为例,从经济发展水平、区域发展优势、自然基底、生态服务、特殊生境5个维度选取17个指标构建土地利用综合评价体系,应用熵权法确定权重,以ArcGIS为技术支撑平台,对2011—2016年湖北省各市土地利用水平进行分析。结果表明,空间上土地利用综合水平在西部和南部上升明显,东部黄冈市呈下降趋势,而中部地区并无明显变化;土地利用综合水平呈缓慢上升趋势,土地社会经济利用水平呈较快发展趋势,土地自然利用水平变化不明显;2011—2016年湖北省土地利用总体上处于中低水平,且土地利用的社会经济和自然两方面发展不协调。此外,为促进湖北省各市土地资源的合理利用和城市的可持续发展,根据研究结果提出了相应的政策建议。
The orderly use of land is the basis for sustainable urban development.The rational use of land resources is related to the development of social economy and natural environment.Taking Hubei province as an example,17 indicators were selected from five dimensions:economic development level,regional development advantage,natural basement,ecological service and special habitat to construct a comprehensive land use evaluation system.The entropy weight method was used to determine the weight,and ArcGIS was used as the technical support platform to analyze the land use level of each city in Hubei province from 2011 to 2016.The results show that the comprehensive level of land use in space has increased significantly in the west and south,and Huanggang city in the eastern part has a downward trend,while there is no obvious change in the central region;the comprehensive level of land use is slowly increasing,and the level of land socio-economic utilization is developing rapidly.The land use level has not changed significantly;from 2011 to 2016,land use in Hubei province is generally at a low level,and the socio-economic and natural development of land use is not coordinated.In addition,in order to promote the rational use of land resources and the sustainable development of cities in Hubei Province,corresponding policy recommendations are proposed based on the research results.
