基于灰色关联度的镇域村庄布局影响因素分析——以甘肃省达板镇为例

摘要

利用甘肃省达板镇土地利用数据库、行政村以及统计年报数据,基于GIS技术对数据进行空间化处理,并采用灰色关联度模型对影响因素与村庄布局的关联度进行了分析.结果表明,自然、社会、经济三方面的8个因素对村庄布局的影响程度不同,按照关联度从高到低的顺序依次为坡度(0.841 1)、总人口规模(0.806 7)、劳动力规模(0.803 3)、水源(0.773 8)、高程(0.769 1)、耕地规模(0.733 8)、交通(0.713 4)、人均纯收入(0.518 9).因此,在制定村庄布局规划或者研究村庄布局肌理的过程中理应差异化对待,有主次之分.%Taking Daban Town in Gansu Province as an example,based on the GIS technology,land-use database of villages and town,statistics yearbook of villages.Then,the correlation degree between the factors and the village layout is analyzed by using the grey correlation degree model.Results show that 8 factors concerning the three aspects of nature,society and economy have different impact on village layout.According to the order from high to low of the correlation degree,the sorting order of 8 factors is slope(0.8411),total population scale(0.806 7),labor scale(0.803 3),water source(0.773 8),elevation(0.769 1),cultivated land scale(0.733 8),transportation(0.713 4) and per capita net income(0.518 9).Therefore,the factors are supposed to have the primary and the secondary for the study on matiere of village layout and the village layout planning.It is important for relevant departments to provide the theoretical support and decision-making reference.
