地理国情监测绿化指数调查的技术方法研究

Study on the Technique and Method of National Geographical Conditions Monitoring and Virescence Coverage Survey

主要阐述位于城市中心城区内开展绿化覆盖的调查,研究如何运用遥感反演调查技术方法,调查出中心城区内绿化覆盖状况,通过分类精度评价能符合精度要求后,进一步开展城市绿地景观格局的分析,计算出中心城区内的绿化覆盖率、绿地廊道的指数等多项城市的绿地景观指数,为自然资源管理的宏观分析及各级政府部门提供了地理国情数据支撑。

This paper mainly expounds the investigation of the virescence coverage in the central urban area,and studies the method of using remote sensing inversion to investigate the greening coverage in the central urban area.With the acceptable classification accuracy,it further analyzes the landscape pattern of urban green space,calculates the green space landscape index of many cities,such as the rate of green space coverage and the index of green space corridor in central urban area,which provides geographical data support for the natural resources management of macro-analysis and government departments at all levels.
