Consistency Analysis and Linking of Farmland Natural Quality Grade and Cultivated Land Productivity Assessment
摘要
Abstract
Taking Qingfeng county as an example , based on GIS and multivariate statistical analysis method , using the maxi-mum yield per unit area in fertilization tests as the unified reference point , we studied the consistency of farmland natural quality grading result and cultivated land productivity assessment result , and explored the linking of these two kinds of results .The results indicated that the spatial consistency of farmland natural quality grading result and cultivated land productivity assessment result in Qingfeng county reached 66.43%.The key factors which caused the unconsistency of two kinds of results included the mineralized degree of groundwater (a factor in cultivated land productivity assessment ) and the salinized degree of farmland (a factor in farm-land natural quality grading).A model was established for the linking of farmland natural quality index and cultivated land produc -tivity index in the same area, which could be used for the mutual transformation of the above two kinds of results .关键词
