Evaluation of Arable Land Reserve Resources in Beidahuang Group of Heilongjiang Province

随着我国建设进程的加快,导致耕地存量正逐渐减少,威胁着国家粮食安全。耕地后备资源是补充耕地的重要来源,是缓解粮食安全的重要途径。本文以黑龙江省北大荒集团为研究对象,通过对耕地后备资源适宜性评价体系各因素的分析,构建了耕地后备资源适宜性评价指标体系,对北大荒集团耕地后备资源适宜性进行了综合评价,并划分了高适宜、中适宜和低适宜区域和面积,结果可为北大荒集团耕地后备资源开发提供参考。

With the acceleration of China’s construction process,the stock of cultivated land is gradually decreasing,threatening the national food security.Cultivated land reserve resources are an important source of supplementary cultivated land and an important way to alleviate food security.This paper takes Beidahuang Group of Heilongjiang Province as the research object,constructs the suitability evaluation index system of cultivated land reserve resources through the analysis of various factors of the suitability evaluation system of cultivated land reserve resources,makes a comprehensive evaluation of the suitability of cultivated land reserve resources of Beidahuang Group,and divides the high suitability,medium suitability and low suitability regions and areas.The results can provide reference for the development of cultivated land reserve resources in Beidahuang Group.
