【摘要】：城市绿地对雨水的流失有显著的缓解作用,城市绿地的合理规划与建设对雨水资源的有效利用有巨大的影响。以郑州市为研究对象,基于2011年8月份TM影像,分析不同高程区间内郑州市区绿地面积、绿地斑块数量与汇水面面积的相关关系,同时结合气象观测资料,道路、公园、防护绿地分布资料等,对城市绿地对雨水资源有效利用提出合理的途径。结果表明:绿地面积、绿地斑块个数与汇水面均呈极显著正相关。因此,建议郑州市在增加绿地面积的基础上提高绿地斑块数量,在城市绿地设计多目标中实现雨水资源利用多目标,最终达到改善郑州水环境和减轻城市内涝灾害的目的。
[Abstract]:Urban green space has a significant mitigating effect on Rain Water's loss, and rational planning and construction of urban green space has a great impact on the effective utilization of Rain Water resources. Based on TM image of August 2011 in Zhengzhou City, this paper analyzes the correlation among green area, patch number and water surface area in Zhengzhou urban area in different elevation regions, and combines meteorological observation data, roads, parks, etc. The distribution data of protected green space put forward a reasonable way to utilize Rain Water resource effectively in urban green space. The results showed that there was a significant positive correlation between green space area and patch number. Therefore, it is suggested that Zhengzhou should increase the number of green patches on the basis of increasing the area of green space, realize the multi-objective of rainwater resources utilization in the multi-objective of urban green space design, and finally achieve the purpose of improving the water environment of Zhengzhou and alleviating the urban waterlogging disaster.
