摘要：

为贯彻落实最严格的耕地保护制度，进一步规范耕地占补平衡管理，丹江口市开展了全域耕地后备资源调查评价工作。以湖北省下发的丹江口市耕地后备资源调查评价底图数据为研究对象，根据《湖北省耕地后备资源调查评价工作方案》（鄂自然资办文〔2021〕15号）中评价标准，对丹江口市耕地后备资源进行评价工作，并且对评价为宜耕的图斑进行更深一步的风险评价。评价结果显示：本次丹江口市耕地后备资源调查评价总宜耕面积为106.5 hm2，占评价底图面积的43.15%，其中由其他草地评价为宜耕共56.2 hm2，由裸土地评价为宜耕共50.3 hm2。宜耕的区域都处于中风险及以下，低风险面积较少，仅4.9 hm2，占评价底图面积的1.97%，较低风险区面积74.5 hm2，占评价底图面积的30.18%，中风险区面积约27.1 hm2，占评价底图面积的10.99%。丹江口市后备耕地中等生态风险区面积较大，主要分布在南水北调水库区周围，需要进行适量的生态保护和修复。

Abstract:

To implement the strictest farmland protection system and further standardize the balance management of arable land occupation and compensation, Danjiangkou City had carried out the survey and evaluation of arable land reserve resources in the whole region. Taking the base map data of farmland reserve resources survey and evaluation in Danjiangkou City issued by Hubei Province as the research object, according to the evaluation criteria in the “Work Plan for the Survey and Evaluation of Cultivated Land Reserve Resources in Hubei Province” (EZZB [2021] No.15), the evaluation of farmland reserve resources in Danjiangkou was carried out, and further risk assessment was carried out on the plots that were evaluated as suitable for cultivation. The evaluation results showed that the total suitable arable land area of the survey and evaluation of cultivated land reserve resources in Danjiangkou City was 106.5 hm2, accounting for 43.15% of the area of the assessment base map. Among which 56.2 hm2 was grassland and 50.3 hm2 was bare land. The areas suitable for cultivation were at or below the middle risk, and the area of low risk was only 4.9 hm2, accounting for 1.97% of the area of the assessment base map. The area of lower risk was 74.5 hm2, accounting for 30.18% of the area of the assessment base map. The area of medium risk was about 27.1 hm2, accounting for 10.99% of the area of the assessment base map. The reserve cultivated land in Danjiangkou City had a large area with medium ecological risk, which was mainly distributed around the reservoir area of the South-to-North Water Diversion Project, and required appropriate ecological protection and restoration.
