摘要
Based on the object-oriented concept,the hyperspectral intelligent monitoring system of major soil nutrients was designed and developed by using C# and ArcGIS Engine in combination with Microsoft SQL Server.The system mainly includes the following functions：file operation,basic map operation,spectral preprocessing,model management,nutrient content quick calculation,spatial distribution analysis,user management and so on.This system can accomplish the input and preprocessing of soil hyperspectra,and calculate the content of major nutrients,such as soil organic matter,nitrogen,phosphorus as well as potassium quickly and intelligently based on hyperspectral data.Thereby,the soil nutrients regional distribution in the research area can be analyzed by using the principle of geostatistics.This study can not only promote the practicability of soil quantitative remote sensing,but also provide references for the decision-making of agricultural fertilizing.
基于面向对象理念,综合采用C#、ArcGIS Engine和Microsoft SQL Server设计并开发了土壤主要养分高光谱智能监测系统。系统主要包括文件操作、基本地图操作、光谱预处理、模型管理、养分含量快速计算、空间分布分析、用户管理等功能。系统可完成土壤高光谱数据的输入与预处理,并基于高光谱数据快速、智能计算采样点土壤主要养分(有机质、碱解氮、有效磷和速效钾)含量,进而利用地统计原理,实现研究区土壤养分的区域分布分析,不仅可促进土壤定量遥感的实用化和精准农业的发展,而且可为农业施肥决策提供依据。
