江汉平原不同类型的渍害低产田面积已达2.9×105 hm2;综合治理农田渍害、改良利用涝渍低产田,长期以来一直是该区农业发展中的首要任务。文章从区域水文地质、地貌条件、恳殖和耕作的影响等方面,分析了江汉平原农田渍害与土壤潜育化形成的原因,并提出了综合治理农田渍害和改良涝渍低产田的对策。根据对现有资料的分析,认为在目前的社会经济条件下还难以从根本上阻止江汉平原农田渍害和土壤潜育化的发展。
Different types of low-yielding paddy fields have reached 2.9 × 105 hm2 in Jianghan Plain. Comprehensive treatment of farmland waterlogging and improved utilization of low-waterlogged fields have long been the primary task in agricultural development in this area. This paper analyzes the causes of farmland soil erosion and soil gleization in Jianghan Plain from the aspects of regional hydrogeology, topography, impact of planting and cultivation, and puts forward the countermeasures of comprehensively controlling farmland waterlogging and improving waterlogging and low yield field . According to the analysis of available data, it is considered that under the current social and economic conditions, it is still difficult to fundamentally prevent the development of soil erosion and soil gleization in the Jianghan Plain.
