摘要
基于"Quick bird"卫星遥感数据对深圳特区市级公园及市政道路绿地现状进行判读,并结合实地调查数据进行比较分析。结果表明,判读结果与实地调查数据相符程度较高,尤其是面积相对较大的公园绿地;对于以乔木为主的分车道绿地,由于判读为覆盖面积,与调查面积出现一定差异;深圳市市政公园绿地中乔灌草所占比例最大,其次为乔草和草坪;市政道路绿地与公园绿地相比,乔木、乔草、灌草、灌木类型比例均有所上升,草坪面积大幅减少,乔灌草复合结构依然占绝对优势。
Actuality condition of urban park and municipal road green-land were described and analyzed based on ＂Quick bird＂satellite data and investigation data. The results showed that interpretation result based on ＂Quick bird＂ satellite data has more close to investigation data, especially for urban park. For driveway greenbelt,there are bigger difference between Quick bird satellite data and investigation data, because the driveway green belt is consist of big trees,which satellite data is cover area. In urban park, vegetation of turf-shrubs-arbor occupies the largest proportion, followed by turf-arbor and turf. The proportion of arbor, arbor-turf, shrubs-turf, shrubs increased in municipal road green-land, while the area of turf declined distinctly compared to urban park.
