Analysis Of Cultivated Land Quality Potential In Shanxi

The purpose of this study is to present the distribution,the overall quality of cultivated land utilization and clarify the future direction,to improve the province’s quality of cultivated land,cultivated land to solve the resource scarcity problem,provide support for the implementation of the "13th Five-Year" planning objectives.According to the above requirements,this research will analyze the evaluation of cultivated land quality results and the actual survey data,study the quality of cultivated land potential to enhance construction of cultivated land quality evaluation model,the potential to enhance regional distribution system,a comprehensive analysis of partition,put forward measures and suggestions to improve the quality of cultivated land.The best difference method is adopted in this study.Taking the evaluation unit of the highest natural index in the two level as the standard,the natural equal index of each grading unit is subtracted from this standard,and the difference is found to enhance the quality potential of cultivated land.In 1 VII(Datong Basin area)index area as an example,after a preliminary experimental verification,grading and zoning effect.This method is used to calculate the potential.The results are the potential upgrading map of the two level zone of 13 Standard tillage systems,and the potential space for each partition is marked.The results of the study show that the high quality area of cultivated land is highly distributed,and most of them are distributed at 1200 meters above sea level.They are mainly distributed in the central part of Datong,the western part of Shuozhou,the central and western part of Xinzhou,the northeast of Jinzhong,the northeast and the west of Linfen,the southeastern part of Changzhi,the northwestern part of Yuncheng,and the northeast part of Jincheng.
