【Abstract】 Jianli County is known as a major grain-producing couny in China. This paper mainly researched the current production situation of grain production and its spatial and temporal changes in the county by adopting data from ground measure, farm-household questionnaire and remote sensing images. Then methods of Grey Relational Analysis and Analytic Hierarchy Process(AHP) were applied to identify main factors affecting the grain production change and problems needed to be solved in Jianli County. Based on the above study results, some countermeasures were proposed, i.e. low-yield.cropland transformation, paddy-dryland crops rotation, scientific application of fertilizer and pesticides and agricultural Infrastructure construction improvement, et al. analysis.更多还原
