摘要
【目的】采用综合指数法对轮台县耕地地力进行评价。【方法】在GIS支持下,应用第二次土壤普查成果,收集轮台县的行政区划图、土地利用现状图、土壤图以及测土配方施肥数据,同时,选取与剖面性质、土壤理化性质、立地条件3个方面相关的12个影响因子建立耕地地力评价体系及模型,在GIS的支持下对轮台县耕地地力进行综合评价。【结果】轮台县40 486.67 hm2耕地中,根据地力水平分为五个等级,一至五级地分别占耕地的18.23%、44.77%、13.76%、13.52%、9.71%。【结论】轮台县耕地地力大部分属于中等水平,研究结果能准确的反映轮台县耕地质量的空间分布情况,为研究区耕地质量提升、种植结构调整、精准农业的实施提供科学的参考依据,有助于耕地资源的科学管理。
[Objective] The project aims to evaluate Luntai County cultivated land fertility by using comprehensive index.[Method] With the support of GIS,the application of the second soil survey,collection of Luntai County administrative map,land use map,soil map and formula fertilization by soil testing data,and at the same time,the establishment of evaluation system and model of cultivated land fertility in 3 aspect conditions and section properties,physical and chemical properties of soil,site selection of 12 effects factors related to GIS,a comprehensive cultivated land fertility evaluation in this county was carried out.[Result] The results suggested that among the 40,486.67hm2 farmlands area in Luntai County mapped,the fertility of grade from one to five accounted for 44.77％,13.76％,18.23％,13.52％,and 9.71％ respectively.[Contusion] Luntai County cultivated land fertility mostly belong to the middle level,the spatial distribution of cultivated land in Luntai County,the results can reflect the quality accurately,and provide scientific Referencess for the implementation of quality of cultivated land,planting structure adjustment,promotion of precision agriculture,scientific management is helpful to cultivated land resources.
