【目的】采用综合指数法对博湖县耕地地力进行评价。【方法】以新疆巴音郭楞蒙古自治州(以下简称巴州)州博湖县为例,选取与剖面性状、土壤理化性质、土壤管理和立地条件相关的13个因子作为指标,在GIS技术支持下,运用层次分析法和模糊数学法对全县耕地质量进行了评价。【结果】在博湖县19 141.27hm~2耕地中,一~四等地分别占耕地面积的比例为5.37%、43.47%、31.87%、19.29%。【结论】博湖县耕地地力处于中等水平,三、四等地主要受自然因素土壤理化性质不良、肥力较低、盐渍化程度高和人为因素土壤管理水平低的影响。
【Objective】 The comprehensive index method was used to evaluate the cultivated land productivity in Bohu County. 【Method】 Taking Bohu County in Bayinguoleng Mongol Autonomous Prefecture of Xinjiang as an example, we selected 13 factors related to the profile traits, soil physical and chemical properties, soil management and site conditions as indicators, Under the use of analytic hierarchy process and fuzzy mathematics method to evaluate the quality of farmland in the county. 【Result】 Among the 19 141.27 hm ~ 2 cultivated land in Bohu County, the proportions of the first to fourth cropland occupying arable land area were 5.37%, 43.47%, 31.87% and 19.29% respectively. 【Conclusion】 The soil fertility of cultivated land in Bohu County is at moderate level. The soil fertility in third, fourth and fourth places is mainly affected by the poor physical and chemical properties of natural factors, low fertility, high salinization and low man-made soil management.
