全国土壤水分及作物长势地面监测体系的初步构想

土壤水分和作物长势监测是农情监测系统中不可缺少的重要组成部分。土壤水分含量直接影响着作物生长，作物长势的好坏与作物产量有着密不可分的关系。该文从应用角度出发，通过分析自然环境及作物布局等区域特征，进行监测样点布设，明确了监测内容及评价指标，并构建网络信息化平台，建立大尺度的地面土壤水分及作物长势监测系统，实现数据网络化管理，同时结合遥感信息进行综合应用，及时为政府提供决策支持。

Primary idea of national ground monitoring system for soil moisture and crop growth

Soil moisture and crop growth are important parts of characterization of agriculture information. Soil moisture directly influences the crops growth, and crops growth is closely concerned with crop yields. From the view of application, the monitoring sample points were set up, the monitoring content and evaluation indices were established and the network information platform was constructed through areal characterization of natural environment and crop distribution. Also the ground monitoring system of soil moisture and crop growth in large scale was constructed which realized administration of data networks. Combined with remote sensing information, the application of ground monitoring system can supply the decision-malcing support for government.
