“衡邵干旱走廊”土壤墒情自动监测系统研究

Study on Soil Moisture Automatic Monitoring System in “Heng Shao Drought Corridor”

旱灾是湖南省各类自然灾害中最主要的自然灾害之一,基于湖南省抗旱体系不完善,旱情信息来源少、监测技术手段落后等问题,确定以湖南省常年旱情较为严重的"衡邵干旱走廊"为典型研究区域,对土壤墒情自动监测系统进行研究。在研究过程中,采用现代数据采集技术,成功解决土壤墒情信息的自动采集、传输、存储和处理等关键技术问题。在土壤水分传感器性能综合比选、墒情站设计和实施方面积累宝贵经验,为今后抗旱减灾工作提供技术指导。

Drought is one of the main natural disasters of Hunan Province. Because drought relief system is not perfect, drought information source is little, monitoring technical means is backward in Hunan province, the article chooses ＂Heng Shao drought corridor＂ which is more serious drought perennial of Hunan Province as a typical research area, and studies the soil moisture automatic monitoring system. In the course of the study, it adopts modern data acquisition technology, successfully solves key technology problems of automatic collection, transmission, storage and processing in the soil moisture information. It accumulates valuable experience in the aspects of soil moisture sensor performance comprehensive selection, moisture station design and implementation and provides technical guidance for drought relief work in the future.
