Park green space is a typical open area in cities and play a great significance for maintaining urban ecology and healthy living environment.This arrticle takes the main urban area of Lanzhou City as an example,and using GIS technology and Fragstats 4.2 software to caculate the supply quantity and quality indicators of various park green spaces.The following conclusions are drawn:(1)The composition of park green spaces in Lanzhou City is uneven,with significant differences in green space area and spatial layouts that are not entirely resonable,exhibiting characteristics of'overall dispersion and local concentration';(2)The diversity of Lanzhou park green space is low,and the degree of landscape fragmentation is high.There are significant differences in the aggregation of various types of green space,with generally low average fractal dimensions,which are detrimental to the protection of biodiversity.On this basis,it is proposed to optimize the optimization of the green land pattern of the main urban area of Lanzhou City,providing reference for related research.
