Identification and classification of cultivated land restoration potential under the background of the Large Occupation and Compensation policy
摘要
Abstract
Scientifically identifying key areas with potential for cultivated land restoration and conducting a classification evaluation of arable suitability is of great significance for implementing the Large-scale Requisition and Compensation policy for cultivated land,ensuring national food security,and supporting the high-quality development of the regional economy.This study took Wuhan City as the research area.Based on the Third National Land Survey data,non-cultivated agricultural land parcels labeled as recoverable or engineerable recoverable were used as the maximum theoretical potential value,restrictive evaluation indicators and arable suitability evaluation indicators were constructed respectively from multiple dimensions such as territorial spatial planning,natural suitability,infrastructure conditions,and geographical location conditions,to measure and identify key areas with potential for cultivated land restoration and their spatial distribution patterns.The results showed that constructing a method system for identifying and grading cultivated land restoration potential from the two aspects of restrictiveness and arable suitability,and clarifying the key areas of cultivated land restoration potential,helped to improve the scientificity and rationality of project approval and site selection,formulation of priority plans,and index allocation for cultivated land restoration projects.After deducting restrictive factors,the area with potential for cultivated land restoration in Wuhan City was 532.97 km2,indicating a relatively large potential for cultivated land restoration.The resources of cultivated land restoration potential in the central urban area were extremely scarce,and 98.6％of the cultivated land restoration potential was located in the peripheral development zones and new urban areas.The comprehensive evaluation scores of the arable suitability of cultivated land restoration potential in Wuhan City ranged[64,98],with an average score of 83.9.It was divided into four levels from high to low:the most suitable cultivation area,the relatively suitable cultivation area,the moderately suitable cultivation area,and the low-suitability cultivation area,with areas of 157.39,200.11,146.40 km2,and 29.07 km2 respectively,The proportions accounted for 29.5％,37.5％,27.5％,and 5.5％respectively.Implementing corresponding restoration plans and targeted measures for different types of areas could minimize the risk of abandonment of the restored land again.In 2023,83.57％of the restored cultivated land in Wuhan City was within the scope of arable suitability evaluation.Among them,the proportion located in the most suitable cultivation area and relatively suitable cultivation area was the highest,and the research results were highly consistent with the actual situation.This study can provide methodological references for carrying out project approval and site selection,as well as formulating priority plans for cultivated land restoration projects under the background of the Large-scale Occupation and Compensation policy.It holds important guiding and practical values for local governments to promote cultivated land protection work.关键词
