摘要
以黄羊镇土壤图、黄羊镇土地利用现状图、黄羊镇行政区划图和黄羊镇地貌类型分区图叠加形成适宜性评价的甜菜适宜性管理单元总图,选取研究区内对甜菜生长影响较大,并且具有区域空间变异明显、时间序列上相对稳定特征的8个因子,建立评价指标体系,拟合各个因子隶属函数,应用层次分析法,在GIS软件中,通过累计分析计算,将研究区内耕地适宜性划分为3个等级。结果表明:黄羊镇甜菜生产适宜性的影响程度从大到小依次为:海拔、有效土层厚度、坡向、年降水量、有机质、质地、≥10℃积温和有效磷。其适宜性等级分别为:高度适宜区面积为12955.5 hm^2,占研究区总面积的63%,适宜区面积为6779.8 hm^2,占研究区总面积的33%,不适宜区面积为814.5 hm^2,占总面积的4%。
Suitable evaluation on planting sugarbeet was illustrated in Huangyang town. The area soil map, present situation of land use map, administrative division map and geomorphic type partition map of Huangyang town were into superposition to form management unit chard which were suitable for evaluation, and selection of six main factors influence on sugarbeet set up evaluation index system by GIS software. The Results revealed that eight main factors, according to influence on sugarbeet production suitability, were arranged in a order from big to small as follows： the influence of altitude, effective soil layer thickness, slope direction, annual rainfall, organic matter, texture, 10℃ or higher accumulated temperature and effective phosphorus. The sugarbeet production suitability degree of Huangyang cultivated land was classified as three levels, high suitable area （12955.5 ha）, the suitable area （6779.8 ha） and unsuitable area（814.5 ha）, accounting for 63%, 33% and 4% of the total area of the studied area, respectively.
