摘要: 土地利用/土地覆被是地理环境内部相互作用的结果,集中体现了人地关系的特征、属性和作用机制。传统对土地利用/土地覆被的监测研究方法仅能够反映不同时期土地利用类型面积的数量变化,无法实现对变化信息的定位分析与可视化表达。采用图谱分析的方法,借助RS和GIS技术,对山西省滹沱河流域忻州段1995—2005年、2005—2015年两个时间段内土地利用类型的时空演变特征进行分析,实现了对土地利用类型转换的定量分析和空间的定位描述。结果表明:受到社会经济发展和生态环境保护的双重影响,滹沱河流域忻州段土地利用格局发生不同程度的变化。该研究为土地利用/土地覆被的时空演变分析提供了一种方法,能够为滹沱河流域忻州段合理规划土地利用提供依据。Abstract: Land use/land cover is the result of interaction between geographical environment,which embodies characteristics,attributes and mechanism of human-land relationship.Traditional monitoring method of land use/land cover only reflect quantity variation of proportion to land use type in different times,which cannot be realized location analysis and visual expression of change information.So,method of TUPU analysis and technology of RS and GIS were used,which could be analyzed of spatial-temporal evolution characteristics of land use types from 1995 to 2005 and 2005 to 2015 of Hutuo river basin in Xinzhou section,quantitative analysis of land use type conversion and location description of conversion space could be realized.Results showed that land use patterns had changed by varying degrees because of dual effect of socio-economic development and ecological environment protection.A method was provided to analyze spatial-temporal evolution of land use/land cover,which also provided a reference basis for rational planning of land use of Hutuo river basin in Xinzhou section.
