摘要
为探究乡村振兴背景下灾毁耕地复垦潜力,推进乡村振兴战略,以重庆市北碚区灾毁农用地为例,野外调查灾毁农用地的数量、分布和类型,总结研究其现状特点,并构建灾毁耕地复垦潜力评价指标体系,对灾毁耕地进行复垦潜力评价研究。结果表明:Ⅰ级潜力类型的灾毁耕地经过相应的复垦措施,能够恢复成优质农田;Ⅱ级潜力类型的灾毁耕地有较好的农业发展基础,可因地制宜发展本地蔬菜种植;Ⅲ级潜力类型的灾毁耕地大多数地表破坏程度较严重,灌溉条件难以保证并且排水设施不健全,可适度发展牧草业;Ⅳ级潜力类型的灾毁耕地改造难度大,限制性因素较多,几乎不能复垦为耕地,可适度发展林业。研究表明,北碚区灾毁耕地复垦虽然受到一定因素限制,但该区降水充足、土壤水分状况较好、有机质含量较丰富,农业生产潜力较大。
In order to better understand the reclamation potential of disaster devastating farmland and promote the Rural Revitalization strategy, the study took disaster destroyed arable land in Beibei District, Chongqing City as an example. We surveyed the number, distribu?tion and classes of the destroyed land and summarized status features to evaluate reclamation potential for disaster devastating farmland.The results showed that the land of type Ⅰ could be restored to high-quality farmland through corresponding reclamation measures. The land reclamation of type Ⅱ had good agricultural foundation and could plant vegetables according to local conditions.The land of type Ⅲ was hard to ensure irrigation and drainage facilities with surface seriously damagd, and the pasture grass industry could be developed mod?erately. The land of type Ⅳ was difficult to transform. Clue to many restrictive factors, which could hardly be reclaimed as cultivated land,and forestry could be developed moderately. The research results showed that the reclamation of the disaster devastating farmland in Beibei District was limited by certain factors. However, there had sufficient rainfall, good soil moisture, rich organic matter content for higher agri?cultural production potential.
