基于面向对象技术的吉林省西部景观格局研究

Research on Landscape Pattern of the Western Jilin Province Based on the Object-oriented Technology

基于面向对象分类方法,以吉林省西部为研究区,快速准确地提取了吉林省西部的地理景观格局,并分析了其空间分布规律。结果表明,利用面向对象技术,结合遥感影像纹理信息、光谱特征和形状特征等提取的生态景观类型精度较高、实用性较好;2012年吉林省西部的主要生态景观类型为旱地,分布于区域南部和东北部,未利用地面积最小,对于吉林省西部生态环境监测具有重要意义,为政府宏观决策提供了技术支持。

Based on the object-oriented classification method, taking the western Jilin Province as the research area, we extracted the geographical landscape pattern of the western Jilin Province quickly and accurately, and analyzed its spatial distribution rules in this paper. The results show that the ecological landscape type,which extracted by the object-oriented technology combining with remote sensing image texture information, spectral feature and shape feature, has a high precision and good practicability. The main type of ecological landscape in the western Jilin Province in 2012 is the dry land, which are in the regional distribution of south and northeast. The unused land area is minimum. This study is of great significance for the ecological environment monitoring in western Jilin Province, and provides a technical support for the government's macro decision-making.
