摘要
以地理国情监测数据为基础,结合国土调查数据,对“耕地”地类图斑进行对比分析研究,挖掘可进行耕地恢复的潜力空间。采用GIS空间分析、遥感解译、数理统计和外业核查方法,对湖北省2020年地理国情监测数据和2021年国土变更调查数据中的“耕地”图斑进行差异性综合分析,研究耕地后备资源潜力空间。结果表明:2020年湖北省地理国情与2021年国土变更调查数据中的“耕地”差异图斑共有711.78万亩,内业判读“确认耕地”和“疑似耕地”图斑共有131.80万亩,经外业核查,实地现状为耕地的图斑占比约55.28%,能够为耕地后备资源空间挖掘提供参考。
Based on geographical conditions monitoring data,combined with territory resource survey data,we comparative analyzed and re-searched the classification patterns of cultivated land to explore the potential space for farmland restoration.We used GIS spatial analysis,remote sensing interpretation,mathematical statistics and field verification methods to comprehensively analyze the differences in the cultivated land pat-terns in the geographical conditions monitoring data and the territory resource change survey data of Hubei Province.And then,we studied the potential space of cultivated land reserve resources.The result shows that there are a total of 7.1178 million mu of cultivated land difference patches in the two data items.Among them,there are a total of 1.318 million mu of confirmed and suspected cultivated land plots in the internal industry interpretation.After field verification,the current situation on site is that the proportion of cultivated land patches is about 55.28%,which can provide reference for the spatial exploration of cultivated land reserve resources.
