摘 要:中国耕地的现状是山地面积大,平地面积小,其中耕地所占比重小。不论是在实践过程中,还是理论研究上,对耕地进行质量评价是需要得到重视的工作。本文使用ArcGIS软件,利用空间分析和统计的方法,研究了阜蒙县耕地自然质量等的数量分布特征和空间分布特征。结果表明:1)阜蒙县国家级耕地自然质量等为8-13等,以10等和11等为主,共占耕地总面积的94.62%。2)阜蒙县国家级利用等主要为11等和12等,占耕地总面积的98.61%;阜蒙县国家级经济等主要为11等和12等,占耕地总面积的99.78%。3)自然质量平均等指数、利用等平均等指数、经济等平均等指数相比上一轮,均无明显变化。The current situation of cultivated land in China is that the area of mountains is large,and the area of land is small.Moreover,the proportion of cultivated land is small.The evaluation of land quality in practical process and theoretical research is the work that should be emphasized and carried out.We studied the quantitative distribution characteristics and spatial distribution characteristics of cultivated land natural quality in Fuxin Mongolian autonomous county based on ArcGIS software by using the methods of spatial analysis and statistics.The results show that:(1) the land natural quality grades at national level in Fuxin Mongolian autonomous county range from 8 to 13,and the main grades are 10 and 11,accounting for 94.62% of the total cultivated area.(2)the main land use grades at national level in Fuxin Mongolian autonomous county are 11 and 12,accounting for 98.61% of the total cultivated area;the main land economical grades at national level in Fuxin Mongolian autonomous county are 11 and 12,accounting for 99.78% of the total cultivated area.(3)There is no significant change in the aspects of natural quality average index,land use average index,and economical average index.
