【摘要】 基于2005-2015年的经济社会发展、农业等相关数据,对浙中城镇群耕地多功能协同与权衡的时空演变规律进行探究,结果表明:金衢盆地内耕地各项功能随时间变化差异明显,物质产出功能稳定上升,劳动力承载功能持续下降,生态环境功能总体上在渐弱,景观美学功能主要呈上升态势;从时间维度看,各耕地功能之间权衡与协同及其变化具有一定差异,2005-2010年协同作用较强,2010-2015年权衡作用较强,整体上协同作用相对较多;从空间维度看,相同耕地在研究区内协同和权衡作用皆有,其中物质产出功能协同作用逐渐减弱,生态环境功能则从权衡作用逐渐转变为协同作用,劳动力承载功能和景观美学功权衡程度逐渐降低,且非显著区数量最多,权衡与协同的空间格局较稳定。不同耕地在研究区多为协同作用,权衡作用较少,且协同及权衡类型分布主要集聚在金华市区一带,功能之间格局随着时间推移而不断发生变化。建议在因地制宜制定合理政策基础上,县域之间加强合作,划分不同的耕地利用分区,充分发挥各区域耕地主导功能与耕地多功能间的协同效应,提高耕地质量。更多还原

【Abstract】 Based on economic and social development data, agriculture statistics, and other related data from 2005 to2015, this study looked into the spatio-temporal evolution of the multi-function coordination and trade-off of cultivated land in town groups in the middle of Zhejiang Province. The results were as follows.(1) The functions of cultivated land varied significantly with time. The function of material output increased steadily, the function of the labour force continued to decline,the function of the ecological environment in general weakened, and the function of landscape aesthetics showed an upward trend.(2) From the point of view of the temporal dimension, there were some differences in the trade-off and coordination of the functions of cultivated land, with the synergy between 2005-2010 and 2010-2015 especially strong.(3) In terms of the spatial dimension, the same cultivated land had synergistic and trade-off effects in the study area, where the synergetic effect of the material output function gradually weakened, and the ecological environmental function gradually transformed from the trade-off function to the synergetic effect. The load-bearing function of the labour force and the trade-off degree of landscape aesthetics decreased gradually, and the number of non-significant areas was the largest. The spatial pattern of trade-off and coordination was stable. Most of the cultivated land in the study area was synergetic, and the trade-off effect was less. The distribution of synergy and trade-off type was mainly concentrated in the Jinhua urban area, with the pattern of changes in function with time continuing. To formulate reasonable policies based on local conditions, it is important to strengthen cooperation among counties, classify arable land use zones, develop the synergistic effect between the dominant function of cultivated land in each region and the multi-function coordination, and improve the quality of cultivated land.更多还原
