摘要
以分析耕地多功能权衡与协同关系为契机,实现耕地利用效率评价,以及耕地利用综合效益的提高和耕地资源与环境的保护。通过ArcGIS10.5、Fragstas4.2、斯皮尔曼秩相关和空间自相关等分析法综合研究发现:(1)物质产出、生态环境、景观美学以及劳动承载力功能的趋势持续增强,其中物质产出与景观美学相较于生态环境与劳动力承载增强较快,劳动力承载功能变化最平稳。(2)耕地各功能间主要呈协同作用,且随时间推移协同程度不断减弱,权衡作用相反。(3)耕地多功能权衡与协同呈现较强的集聚性特征,部分耕地功能空间格局随时间变化较大。同一功能中,物质产出的空间格局较其余三种稳定;不同功能中,物质产出与景观美学间协同较强,生态环境与劳动力承载间权衡较强。故在改善耕地本底质量、合理引导劳动力流向和发展现代观光农业的同时,应加强县域内各部门以及县际之间的合作,科学划定功能区;促进耕地多功能协同,增强耕地综合效益。
This study was conducted to analyze the multi-function balance and coordination relationship of cultivated land and evaluate its utilization efficiency,which can not only improve the comprehensive benefits of cultivated land utilization but also realize the protection of cultivated land resources and environment.ArcGIS10.5,Fragstas4.2,the Spearman rank correlation,and a spatial autocorrelation analysis were used to determine the spatial-temporal pattern and evolution rule of the multi-functional tradeoff and synergy of cultivated land:(1)The trend of material output,ecological environment,landscape aesthetics,and labor carrying capacity continued to increase,among which the material output and landscape aesthetics increased faster than the ecological environment and labor force and the change of labor force carrying capacity was the most stable.(2)There was a synergistic effect among the various functions of cultivated land and the synergistic degree decreased with time;the tradeoff effect was opposite.(3)The multi-function balance and synergy of cultivated land show strong clustering characteristics;the functional spatial pattern of some cultivated land changed significantly with time.In the same function,the spatial pattern of the material output was more stable than the other three.Among the different functions,the synergy between the physical output and landscape aesthetics was strong;the balance between the ecological environment and labor force was also strong.These results were obtained,while improving the quality of the cultivated land background,reasonably guiding the flow of labor force and developing modern tourism agriculture,strengthening the cooperation among various departments within the county and between counties,and scientifically demarcating functional zones.The promotion of the multi-functional synergy of cultivated land and enhancement of the comprehensive benefits of cultivated land was also achieved.
