摘要：In order to deeply analyse the law of urban green space evolution, this paper discusses the change of urban ecological environment effect brought about by green space evolution and its interaction and mechanism. Based on 2007-2018, four remote sensing images of GUI area, the application of remote sensing and GIS spatial information technology, the basic data and sample plot survey, realized based on green space classification diagram. The landscape index, gradient analysis, spatial dynamic analysis methods, such as statistics, quantitative analysis of the urban green space landscape spatial structure evolution and its law of development, with the urban development of green space change of gradient explicit study can be a deeper understanding of the process of landscape pattern, provides the basis for the research of function. The experimental results show that from 2,031 square kilometres in 2007 to 1,364 square kilometres in 2018, the proportion of farmland in urban suburbs decreased by more than 50%. Urban green space has a rising trend in the core urban areas, but changes in the fringe urban areas and suburban areas are complex. With the advancement of urbanization, the total vegetation coverage has decreased by more than 50%, in which the area with high and full vegetation coverage levels has decreased significantly, while the area with no, low and medium vegetation coverage levels has increased.
