【摘要】 运用遥感技术结合GPS精确定位技术,利用1989年和2002年两期遥感数据对生态敏感区域——莫莫格保护区东部的生态环境进行了土地利用类型遥感信息提取、GPS野外验证,总结了本区域环境变化的主要特点,并对其影响原因做了初步分析。同时为了提高遥感信息提取精度,探讨了基于多特征的面向对象分类方法的具体应用。研究表明,面向对象的遥感分类方法应用于环境变化分析有较大的潜力。更多还原

【Abstract】 With the accurate positioning technology of GPS,this paper applies the technology of remote sensing to the sensitive region-the east of Momoge.With a new classification approach-object-oriented classification and two phases of remotely sensed images,the land use/cover classifications of twelve classes are extracted,concluding the main features of the environment changes.Based on the classification,a preliminary analysis of the reason is made.The research shows that object-oriented classification has great potential in environment monitoring.更多还原
