Abstract: |
This paper takes Baicheng county as a study area, according to the provisions of basic farmland that reasonably define basic farmland protection area, related indicators were selected from three aspects of natural quality, location condition and spatial morphology (form) to construct the evaluation index system of cultivated land quality. Using AreGIS platform to realize the quantitative analysis and comprehensive evaluation scores of different indicators. Through comprehensive evaluation model, the comprehensive evaluation score of Baicheng County was between [45.01,94.09], and the cultivated land can be divied into three categories, the area of cultivated land transferable to basic farmland is 38 360.39 hm2, accounting for 42.52%; the cultivated land area suitable for transferring to basic farmland is 9 979.64 hm2, accounting for 11.06%; the cultivated land area not transferred to basic farmland is 41 878.63 hm2, accounting for 46.42%. The results reflected that the comprehensive quality of Baicheng County was good, and the comprehensive score was over 80 points of natural conditions, location conditions,was superior, the patch was regular and contiguous distribution. The results of the evaluation and the basic farmland map were compared and analyzed, and the basic farmland protection target was established for the new round of basic farmland to realize the quality and quantity of cultivated land. |
