摘要
【目的】测度土地利用与生态环境之间的协调程度。【方法】根据临夏州2001—2008年统计资料,设计适合临夏州的土地利用评价指标体系,建立土地利用与生态环境耦合关系模型,对临夏州土地利用与生态环境之间的耦合程度进行分析。【结果】研究期间临夏州土地利用与生态环境的耦合发展度从0.49上升为0.90,总体经历了土地利用滞后型勉强耦合发展模式到土地利用滞后型初级、中级耦合发展模式再到生态环境滞后型良好耦合发展模式的演化过程,土地利用与生态环境的耦合度整体呈现出上升的态势,二者逐渐在趋向良好耦合发展的轨迹。【结论】基于土地利用与生态环境耦合关系的评价模型,对定量评价土地利用与生态环境两系统间耦合度具有较好的可操作性和一定的可信度,有利于对区域土地利用是否科学提出有针对性的建议。
[Objective] To measure the coupling degree between land use and eco-environment. [Method] According to the statistical data of Linxia from 2001 to 2008, we designed a evaluation system of land use suitable for Linxia and built a model to analyse and assess the coupling rela- tionship between land use and eco-environment. [Results] The results showed that coupling de- velopment degree of land use and eco-environment increased from 0.49 to 0.90 during the study period. Overall, coupling relationship experienced the processes of lagging model of land use of reluctant coupling development, lagging model of land use of primary and intermediate coupling development and lagging model of eco-environment of well-coupling development. The coupling degree between land use and eco-environment exhibited a rising trend and it gradually develops to- ward a good trajectory. [Conclusion] The model in this study is a useful tool with high operability and credibility for evaluating the coupling degree between land use and eco-environment, which could be helpful to provide targeted recommendations for regional land use.
