在对全国渍害田现状调查的基础上,整合GIS组件ARCmap的空间分析功能和EXCEL的计算功能,设计了我国各地渍害田治理分区数据库,结合作物种植分区和不同作物的排水深度,提出了不同分区的排水控制深度,可作为我国渍害田治理的参考依据。
Based on the investigation of waterlogged field in national scope, combining the ARCmap components of GIS and EXCEL data processing function, a database of waterlogged field classification in national scope was designed in this article. Combining crop regional planning with different crops' draining depth, the draining depth in different drainage regional was presented, which would provide a basic information for the reclamation of water logged field.
