- Abstract:
-
Urban green space has the significant mitigation on loss of rainwater, rational planning and construction of urban green space has the huge impact on the efficient use of rainwater resources. Taking Zhengzhou City as the research example, based on the TM images of August, 2011, we analyzed satellite images to calculate the elevation range of different green area in Zhengzhou City, the number of green patches and sink surface area of the correlation coefficient, at the same time, and put forward the way on the efficient use of rainwater resources in the urban green space according to the meteorological data, roads, parks, green space protection distribution data, etc. The results showed that the green space area, the number of green patches and the collected water were very significant positive correlation. Therefore, we suggested that on the basis of increase of the green area in Zhengzhou City, number of green patches should be increased, rainwater resources use multi-objective should be realized in urban green space design multi-objective in order to improve the water environment of Zhengzhou and relieve the urban waterlog disaster.
