基于GIS的土壤养分空间变异图件制作和网络共享

本文以临汾市尧都区为例,进行了土壤养分图件的快速制作和网络共享的研究.详细介绍了土壤养分图件制作的技术流程和快速制图技术的优缺点,完成了对临汾尧都区土壤pH、有机质两个养分要素的图件制作.并且对各图件的网络共享进行了可行性研究.结果表明,快速制图技术具有速度快、精度高、成本低廉、可实现网络共享等优点,使得土壤信息实现数字化、网络化,为精准农业的发展提供了基础.

Soil Nutrient Spatial Variation Maps based on GIS and Network Sharing

Taking Yaodu district as an example, the rapid production and network sharing of the soil nutrient maps are researched. The technical process of soil nutrient map and the advantages and disadvantages of mapping technology are detailedly introduced. The maps of two nutrient elements, such as pH and organic matter for Yaodu area in Linfen are finished. Further, the feasibility of network share for maps is studied. The results show that this technology is feasible, has high speed, high precision, low cost, realize the sharing of the network advantage, makes the soil information realizes digitalization, and network, and provides the basis for the development of precision agriculture.
