摘要
积雪和冻土的存在对农田土壤墒情有着重要的影响。积雪和冻土对于土壤墒情的保持有正作用,但相关研究主要停留在对这一现象的描述层面,其规律和机理的研究还有待加强。通过梳理相关监测试验成果,从试验环境、监测项目、监测仪器、监测方法4个方面对积雪和冻土保墒监测试验方案进行分析和设计。在分析已有试验的基础上,结合现有的研究经验,综合考虑试验的真实性、可控性和易于对比性提出3种试验设计方案。试验设计方案的提出可为进一步获取试验数据提供参考。
Covered snow and frozen soil has a significant impact on soil moisture of farmland. More consistent views is that covered snow and frozen soil will promote the soil moisture. But related study is for the description of the phenomenon, its rules and mechanism should to study. Analysis related monitoring test is designed according to the test environments, monitoring contents, monitoring methods and monitoring instruments. On the basis of existing research experience and balance test of authenticity, controllability, and ease of comparison, the paper proposed 3 kinds of test design methods. Test design methods provide a foundation for further data acquisition work and a reference for the same type experimental designs.
