【摘要】：在RS和GIS的支持下集成多源数据,重建了建三江垦区下辖农场1990年、2000年、2010年和2015年4个时期的城镇用地格局。应用动态度模型等探讨了建三江垦区城镇用地扩张的时空特征及区域差异,分析了其驱动因素。结果表明:(1)1990~2015年,建三江垦区城镇用地面积增加了3 237.5 hm2,平均扩张速率为130 hm2/a,扩张速率最显著的阶段是2000~2010年。(2)垦区下辖农场城镇用地扩张时空差异明显,建三江管局所在城镇扩张面积最大;浓江农场扩张相对比例最大;动态度模型分析发现二道河农场扩张速度最快,勤得利农场的城镇用地扩张速率最慢,扩张面积最小。(3)建三江垦区以农场为城镇单元的建设用地扩张模式主要为线性轴状扩张。(4)城镇人口数量、经济水平的不断提升、产业结构的优化与区域政策极大地促进了垦区城镇用地的扩张,交通条件是城镇扩张速率和模式的重要影响因素。
[Abstract]:Integrating multi-source data with the support of RS and GIS, The pattern of urban land use in the four periods of 1990, 2000, 2010 and 2015 was reconstructed. The spatial and temporal characteristics and regional differences of urban land expansion in Jiansanjiang Reclamation area were discussed by using the dynamic degree model. The results show that the area of urban land in Jiansanjiang Reclamation area increased by 3 237.5 hm ~ 2, and the average expansion rate was 130 mm ~ 2 / a. The most significant stage of expansion rate was from 2000 to 2010. The expansion area of the cities and towns in which the Sanjiang Administration Bureau is located is the largest; the relative proportion of the expansion of the Nongjiang farm is the largest; the dynamic degree model analysis shows that the Erdaohe farm expands the fastest, and the urban land expansion rate of the Qindeli Farm is the slowest. The expansion pattern of the construction land in Sanjiang Reclamation area with farm as the urban unit is mainly linear axial expansion. 4) the number of urban population is increasing, and the economic level is improving continuously. The optimization of industrial structure and regional policies greatly promote the expansion of urban land in reclamation area, and the traffic condition is an important factor affecting the rate and mode of urban expansion.
