郑州市城市生态环境变化研究

随着城市化的发展,城市生态环境变化较大.基于遥感技术,利用遥感生态指数对郑州市城市生态环境变化进行评价与检测,以对城市规划建设提供科学依据,从而促进城市健康可持续发展.结果表明:2006年-2017年,郑州市生态环境质量呈下降趋势,其中绿度指标与干度指标对城市生态环境的影响最大;郑州市生态环境变好的区域占18.43%,生态环境变差的区域占42.54%,变差的区域主要为新建成区,这些区域应是今后生态环境改善的重点区域.

Study on Change of Urban Ecological Environment in Zhengzhou

With the development of urbanization, the urban ecological environment changes greatly. Based on remote sensing technology, urban ecological environmental changesin Zhengzhouis evaluated and tested to provide scientific basis for urban plan-ning and construction, so as to promote the healthy and sustainable development of the city. The result shows that from 2006 to 2017the quality of ecological environment in Zhengzhou showed a downward trend, among which the greenness index and the dry degree index had the greatest impact on the urban ecological environment. The ecological environment is becoming better. The ar-ea is 18. 43%, and the ecological environment is becoming poor, the area is 42. 54%. The variation areas are mainly new built areas and these areas should be the key areas for the improvement of ecological environment in the future.
