基于GIS的补充耕地储备项目审核方法研究

Research on the Audit Method of the Supplementary Cultivated Land Reserve Project Based on GIS

地块重复整理、河流淹没、建设占用、未扣除项目区内道路、田坎等线状地物造成的补充耕地数量不符合要求,违规将现状为林地、园地的新增地块重新整理并作为占补平衡新增耕地,系统录入与实际规模不一致等问题,造成的补充耕地数量基础数据不扎实,严重影响了耕地占补平衡政策的有效落实。该研究在总结地方实践经验的基础上,基于GIS平台,对新增补充耕地储备项目(或已备案的土地整治项目)进行审核,主要包括项目图斑及面积审核、项目重叠情况审核、现状库审核、遥感影像疑似判读、野外调查等5个部分,为摸清"家底"(补充耕地储备指标的数量),顺利、有效地推进耕地占补平衡政策工作提供了依据,也为新增补充耕地储备项目审核系统的建立提供了参考。

Due to lot repeated finishing,river flooding,building occupation,not deductions of roads,field ridge within project area,reorganizing of woodland and garden as new cultivated land,inconsistence of system entry and the actual size and other issues,the basic data of additional land quantity was not solid,which seriously impacted the effective implementation of the policy of arable land balance.On the basis of summarizing local experience,based on the GIS platform,the new additional land reserve project （or have filed land remediation projects） were reviewed,including spot and area auditing,project overlay auditing,status auditing,remote sensing image interpretation and field investigation,so as to provide reference for grasping the ＂real situation＂ （supplementary amount of cultivated land reserve indicators）,effectively promoting the balance of arable land,also provide a basis for the establishment of new additional land reserve project audit system.
