摘要
为充分了解兰州市各县区耕地利用状况,本文利用综合评价法及空间分析法对兰州市2008-2017年耕地多功能演变规律进行时空分析。结果表明,(1)从时序上来看,2008-2017年,兰州市耕地多功能主要以粮食生产功能及社会保障功能为主。(2)从空间上来看,各县区所发挥的耕地功能各不相同,其中永登县及榆中县为耕地总功能做出重要贡献。该研究结果可以为政府制定科学、合理的耕地多功能利用布局方案提供理论依据。
In order to fully understand the utilization of cultivated land in various counties and districts of Lanzhou,this paper uses comprehensive evaluation method and spatial analysis method to analyze the multi-functional evolution law of cultivated land in Lanzhou from 2008 to 2017.The results show that,(1)from a tim e series perspective,from 2008 to 2017,the multi-function of cultivated land in Lanzhou City was mainly based on the functions of food production and social security.(2)From a spatial perspective,the functions of cultivated land in different counties are different.Among them,Yongdeng County and Yuzhong County are the total cultivated land.Function makes an important contribution.The research results can provide a theoretical basis for the government to formulate a scientific and reasonable layout plan for the multi-functional use of cultivated land.
