我国是一个洪涝灾害频繁的国家,而对我国洪灾威胁最大的流域又往往是人口最为集中、经济较发达、耕地密集的区域,我国每年因为洪涝灾害要损毁大量农田,严重威胁到我国的粮食安全和人民的生命财产,制约着社会经济的发展。本文以赣榆区黑林镇等三个乡镇土地复垦项目为研究案例,总结归纳水毁耕地的主要特征:覆盖物多,且成分复杂;耕地层破坏严重;农田基础设施功能基本丧失;原有田块面貌基本受到破坏;还伴随着地面塌陷。最后从土地平整、农田基础设施配置、地力恢复与培育等方向有针对地提出水毁耕地复垦的技术措施与对策。
China is a country with frequent floods and floods, and the most threatened flood watershed in China is often the region with the most concentrated population, more developed economy and intensive arable land. Every year, due to floods and floods in China, a large number of farmland is damaged, seriously threatening the food security of our country And people’s lives and property, restricting the social and economic development. In this paper, three township land reclamation projects in Gulin town, such as Heilong town, are selected as the research cases, and the main features of water damaged farmland are concluded as follows: many coverings and complex components; serious damage to cultivated land; basic loss of farmland infrastructure function; The basic appearance of fields has been destroyed; also accompanied by ground collapse. Finally, from the direction of land leveling, farmland infrastructure allocation, restoration and cultivation of groundwater, the paper put forward some technical measures and countermeasures for the reclamation of waterlogged cultivated land.
