摘 要: 应用EPPL7软件,甘肃临泽生态试验区植被类型、土壤有机质分布、pH、土壤全盐含量分布和地下水位分布可由图像定性、定量表示,实现了由点到面的信息表达,运用空间分析技术,经叠加各生态因子及分析后形成的综合生态图将该区划分为6个类型,可较好地解释实际地面信息,为合理开发、利用草地,建立优化模式提供了背景资料。 The vegetation type,soil organic matter, pH value,soluble salt content and water table in Linzeresearch area can be presented by making eco-maps.Six eco-types in the research area are generated byapplying Epp17 package and spatial analysis techniques which overlap and classify the given eco-factors.The result suggests that eco-map making is a useful tool to interpret the reality and provide reliableinfot mation for rational utilization of the grassland.
