Study on the Adjustment of Basic Farmland Planning Based on the Updating of Agricultural Lands Grading

With B district of A city for example,the quality of its basic farmland was designated based on the updating of agricultural lands grading.The results showed that the average utilization grade of basic farmland designated in current round of planning is 16.82 without considering the updating of agricultural lands grading,while it improves by 0.08 taking into account the updating of agricultural land grading,but still 0.11 lower than that of the last round of planning.The causes to the problems in the current round of overall land planning were proposed,the first is that the urban development hasn't taken the protection of basic farmlands into full consideration;the second is a lack of farmland quality inspection during the land use planning;the third is the untimely update of agricultural land updating results.Finally some solutions were presented,including taking into account the quality of farmland during the land use planning,classifying the high-quality farmlands into the basic farmlands,timely updating the agricultural land grading results and involving the grading results into the engineering of one map.
