摘要
地理信息系统具有对空间数据的存贮和管理能力,还提供强大的空间分析手段,满足了土壤景观生态研究往往要分析大量的庞杂的空间信息的要求。本文利用地理信息系统技术在黄土高原土壤景观生态学研究中开展了土壤景观生态信息系统方面的应用研究,并建立了《黄土高原土壤景观生态信息系统》,分析了黄土高原土壤景观生态信息系统的技术特征,并对建立黄土高原土壤景观生态信息系统的一些问题进行了探讨,为黄土高原土壤景观生态学研究提供科学依据。
Geographical Information System(GIS) can not only store and manage spatial data, but also provide easy ways of spatial analyses, which may meet the demands of soil ecological researches in landscape scale with a lot of spatial data. In this paper,study on establishing soil landscape ecology information system in Loess Plateau are analyzed by using GIS. The technical characters of the soil landscape ecology information system in Loess Plateau are analyzed. Some problems relevant to the establishment of the soil landscape ecology information system in Loess Plateau are discussed. The paper provides scientific theory for sustainable development in Loess Plateau.
