【摘要】 利用郑州市TM卫星影像相并波段数据,研究郑州市的地表亮温和NDVI植被指数与植被盖度情况,发现该市相对亮温等级以弱热岛和中等热岛为主,绿岛面积仅占16.44%,且主要分布在郑州市防风固沙林面积较多的东部区域、森林面积较多的西南山地及沿黄河湿地地带,进而提出科学合理布局城市林业,防止并减缓"热岛效应"的林业发展对策。更多还原

【Abstract】 The brightness temperature data,whose reliability is verified by the observed air temperature,and NDVI data of Zhengzhou urban was acquired from TM image.The result shows that the city’s most area is in weak heat island and medium heat island.The total land area of 16.44% is green island,which is mainly distributed in the eastern region of Zhengzhou City.There are a large number of forests and Hanghe revier wetlands in the eastern region.The article provides the construction of city forest plan to reduce heat island countermeasures.更多还原
