晋南地区小麦—玉米轮作区耕地质量评价研究
Study on Land Quality Evaluation of Wheat and Corn Multiple Cropping Area in Jinnan District
【摘要】 为促进优质、高产、高效的生态农业发展,提高晋南地区小麦—玉米轮作区耕地综合生产能力,通过选取土壤物理条件、气候条件、理化性状、土壤管理等4项因素9项因子,建立中大尺度耕地质量评价体系,应用层次分析法,结合SPSS与GIS手段,对晋南地区小麦—玉米轮作区耕地地力调查与评价。结果表明,研究区域总体耕地质量水平偏低,一、二等耕地的面积占总面积的30.10%,主要集中在汾河下游与涑水河中下游;质量偏差的耕地占总区域69.90%,分布比较均匀。评价结果可为研究区合理施肥与科学管理耕地提供科学依据。
【Abstract】 In order to promote ecological agriculture with high quality,high yield,and high efficiency,this study was conducted to investigate and evaluate the farmland quality of wheat and corn multiple cropping areas in Jinnan for further improving the comprehensive production.A large scale evaluation system was established by analysis of soil physical conditions,climatic conditions,physical and chemical properties,soil management via AHP,SPSS,and GIS.The results showed that cultivated land in this area were of poor quality overall.Cultivated land areas with medium or high quality accounted for 30.10%,which are mainly located in Sushui River downstream and Fenhe River downstream. Cultivated land areas with low quality accounted for 69.90%.The findings of the present study provided a scientific basis for rational fertilization and scientific management of cultivated land.
【Key words】 Quality of cultivated land; Wheat and corn multiple cropping area; Analytic hierarchy process; Large-medium scale;
