【摘要】 城市绿地作为城市结构中的自然生产力主体,在城市系统中起着重要作用。传统的城市绿地调查多采用人工普查并结合统计学方法进行城市绿地调查,需要投入大量的人力和资金,但得到的数据精度和现时性都较差,而采用高分辨率遥感卫星数据与地理信息系统相结合的方法,可以达到对城市绿地遥感数据的快速特征提取和准确的空间统计分析。文章采用基于遥感和GIS相结合的方法,并以深圳市为例,进行了城市绿地特征提取方法的研究和应用分析。更多还原

【Abstract】 Urban virescence as the main element of urban structure play an important role in the city. The investigation of traditional urban virescence mainly by combining artificial investigation with statistic method, needs a great amount of people and money, and data accuracy and timeliness cant satisfy city development. But by combining high resolution remote sensing data with GIS method we can extract urban virescence data and precisely count its spatial distribution. The paper combines remote sensing data with GIS method and takes Shenzhen city as an example to extract vegetation feature data and make a relative analysis.更多还原
