安徽省耕地后备资源调查评价成果分析研究

Study on Evaluation and Investigation of Farmland Reserve Resources in Anhui Province

以安徽省2012年度土地调查数据库作为评价底图,以全省可开垦土地和可复垦采矿用地作为评价对象,采用"限制性"因子法做宜耕性评价。结果表明,安徽省耕地后备资源总量有112 353.13 hm^2,主要体征是总量少、分布不均,主要地类是内陆滩涂和其他荒草地。耕地后备资源开发利用的限制性因素有土地规划、开发成本、生态环境和图斑破碎度。研究结果可为安徽省耕地后备资源合理开发利用提供依据。

With database of 2012 land use status as evaluation base map, arable land and reclamation mining land in Anhui Province as evaluation object, the suitability for cultivation was evaluated using restrictive factor method. The results showed that reserved farmland resource in Anhui Province is 112 353.13 hm^2, the main features are less total amount and uneven distribution, the main land types are in land beach and deseft grassland. Land planning, development cost, ecological environment and degree of fragmentation are the major limiting factors for the development of reserved farm/and resource for cultivation. The results can provide reference for the rational exploitation and utilization of farmland re- serve resources in Anhui Province.
