基于RS和GIS的北京城市副中心绿地系统分析

Green space system of Beijing city sub-center based on RS and GIS

【目的】为了给北京城市副中心绿地提供一种可靠的调查方法,并为副中心增绿建设提供参考。【方法】利用RS和GIS为支撑,以北京副中心的一部分作为目标区域对其进行分析。【结果】2018年研究区绿地覆盖率相比2015年有所增加,但是由于研究区现状空间分布情况所限,基本没有空间可以增加大型绿地。【结论】利用“见缝插绿”和进行立体绿化的方法来增加绿化覆盖率。

【Objective】In order to provide a reliable survey method and a reference for green space construction in Beijing.【Methods】The study utilizes Remote Sensing and Geographic Information System as the support and analyzes part of the Beijing sub-center as a target area.【Results】In 2018,the green coverage rate of the study area has increased compared with 2015.However,due to the spatial distribution of the current status of the area,there is no space to increase the large green space.【Conclusion】This paper puts forward the method of inserting green seam and the suggestion of three-dimensional greening to increase the greening coverage rate.
