【摘要】：为科学辨识土地自然和社会经济属性,综合评定其适建水平、质量高低及其限制状况,立足于损益分析视角以五大连池为例,借助RS与GIS技术,从空间区位、自然地理、社会经济、生态保护4个方面构建17个因子的用地扩低张阻力赋值体系,应用最小累积阻力模型模拟村镇建设用地扩张与生态用地覆盖过程,探讨空间土地利用动态演变的潜在趋势,据此通过损益模型划定镇域空间适建类型,进行土地适宜性评价.结果表明,五大连池镇Ⅰ类(高适宜建设区)、Ⅱ类(较为适宜建设区)、Ⅲ类(较为不适宜建设区)、Ⅳ类(不适宜建设区)用地面积为41.01、138.97、387.85、492.26 km2,分别占镇域面积的3.86%、13.11%、36.59%、46.44%,划分结果可为镇域土地适宜性评价及空间管制规划提供辅助判别的技术方法.
[Abstract]:In order to scientifically identify the natural and social economic attributes of land and comprehensively evaluate the level, quality and limitation of land construction, based on the view of profit and loss analysis, taking Wudalianchi as an example, with the help of RS and GIS technology, from the spatial location, natural geography, In the four aspects of social economy and ecological protection, a low tension assignment system of 17 factors was constructed, and the minimum cumulative resistance model was used to simulate the process of land expansion and ecological land cover in villages and towns. The potential trend of the dynamic evolution of spatial land use is discussed. According to the model of profit and loss, the suitable types of spatial construction in the town area are determined, and the land suitability evaluation is carried out. The results show that The land area of Wudalianchi Town is 41.0118.97.387.85492.26 km2, which accounts for 3.1113.1113.1136.597.595.46.444.The result can be divided into two parts: the area of Wudalianchi town is 41.0118.97.857.85492.26 km2, the area of Wudalianchi town is more suitable for construction area, the class 鈪，
