With the rapid development of social economy in Laoting county,the total amount of cultivated land is continuously decreasing.In order to ensure food security,it is necessary to ensure that the total amount of cultivated land is not reduced and that the quality is improved.Reserve resources of cultivated land are an important source to supplement cultivated land and an important guarantee to realize the balance of cultivated land occupation and compensation in the region.it is of great significance to the rapid and healthy development of social economy.The main contents of this article include an overview of research status of domestic and foreign research on the evaluation of cultivated land reserve resources,theoretical basis,regional overview and data preprocessing,selection of evaluation objects,selection of evaluation units,determination of evaluation indicators,and production of thematic maps,evaluation results,etc.A few parts.Not only did the detailed technical methods for assessing the ploughability of cultivated land reserve resources were elaborated,but also the evaluation results of the type,quantity and distribution of cultivated land reserve resources,and the main limiting factors for uncultivated land were analyzed,and measures for the development of cultivated land reserve resources were proposed.The reclamation proposal lays the foundation for the development and use of the next step in the reserve resources for cultivated land in Laoting County,and provides the decision basis for scientifically formulating relevant policies for the protection of cultivated land.Using the "restrictive factor" evaluation method and the advanced technology of GIS,this paper made an evaluation and analysis of the ploughability of reserve resources of cultivating land in Laoting County.The conclusion was: The reserve resources for suitable plough land in Laoting County are scarce,And the distribution is more fragmented and the quality is not high.With the rapid development of social economy in Laoting County in recent years,the stock of reserve resources for land suitable for cultivation in Laoting County will be even more tense.
