区域植被覆盖度的遥感监测——以济南市为例

Remote sensing Monitoring of Regional Vegetation Coverage Taking Jinan as an Example

植被覆盖度通常被用于反映地表植被的生长状况,是衡量地区环境质量是否良好的一个有效指标。本文以像元二分模型为基础解译遥感影像,可以更加方便地判断出当地的植被覆盖状况。由2001年和2013年的两幅济南市域的遥感影像进行解译得出结果,通过结果对比分析,发现在最近过去的12年中,济南全市的植被覆盖情况基本稳定,但在济南市域内不同的县(市)内,又表现出各自的特殊性。根据局地差异可以因地制宜的制定发展策略,促进济南全市的合理健康发展。

vegetation coverage is usually used to reflect the vegetation growth status,is an effective index to measure the regional environmental quality is good or not. In this paper,interpretation of remote sensing image based on pixel two model,can be more convenient to determine the status of the local vegetation cover. The results of interpretation by two remote sensing images of Jinan in 2001 and 2013. Through the comparative analysis of the results,we found the vegeta-tion cover in a steady development in last 12 years of Jinan,but the different counties in Jinan city also show its own par-ticularity. According to the local differences can suit local conditions to formulate the development strategy,to promote the reasonable and healthy development of Jinan city.
