摘要: 采用改进的TOPSIS法对黑龙江省绥化市2010—2019年土地利用结构进行合理性研究。结果表明,2010—2019年绥化市土地利用结构合理度相对较高,呈波动状态变化,2010年土地利用结构合理度最低,2017年土地利用结构合理度最高,达100.00%,今后可参照2017年土地利用结构进行调整;土地利用类型不同对土地利用结构合理度影响不同,城乡建设用地与土地利用结构合理度的相关性最高,草地与土地利用结构合理度的相关性最低;2011年绥化市各县市土地利用结构合理度均在95%以上,明水县土地利用结构合理度最低,青冈县土地利用结构合理度最高,达98.85%。针对结果,提出控制城乡建设用地和交通水利用地的使用数量,保护耕地,适度开发自然保留地,调整林地、草地、园地和设施农业用地的比例等措施以优化绥化市土地利用结构。

Abstract: The rationality of land use structure in Suihua City of Heilongjiang Province from 2010 to 2019 was studied by using the improved TOPSIS method. The results showed that, from 2010 to 2019, the rationality of land use structure in Suihua City was relatively high, and fluctuated. The rationality of land use structure was the lowest in 2010, and the highest in 2017, reaching 100.00%. So, in the future, the land use structure could be adjusted according to 2017. Different land use types had different impacts on the rationality of land use structure, urban and rural construction land had the highest correlation with the rationality of land use structure, the grassland had the lowest correlation with the rationality of land use structure. In 2011, the rationality of land use structure in Suihua City was above 95%, Mingshui County had the lowest rationality, and Qinggang County had the highest rationality, reaching 98.85%. According to the results, some measures were put forward to optimize the land use structure of Suihua City, including controlling the use of urban and rural construction land and transportation and water conservancy land, protecting cultivated land, appropriately developing natural reserves, and adjusting the proportion of forest land, grassland, garden land and facility agricultural land.

Key words: land use structure, rationality, improved TOPSIS method, spatio-temporal analysis, Suihua City
