Abstract

Based on the meteorological data, Kunming located in the subtropical plateau monsoon climate area, is proved to have clear dry and wet seasons with aboundant precipitation.The light and heavy rain have a great influence on surface runoff.The average annual evaporation is more than the precipitation which results in the soil drought and water shortage every year.According to the measured data of different vegetation configurations in green spaces,it shows that the main soil type in Kunming is light clay soil, and that under the condition of steady infiltration, the cumulative infiltration is more than one year return period precipitation but less than twenty year return period precipitation.By analyzing the efficiency of rain interception by vegetation, it shows that vegetation have obvious effects on delaying flood peak runoff and increasing soil moisture content.Using the Small Storm Event Hydrological Model and Water Balance Formulation to analyse rainfall, runoff, infiltration and evaporation synthetically,the law of runoff can be figured out. Four rainwater management strategies are put forward on based on the above:Simulate nature to make the land work.Manage rainwater in the split-flow way and utilize different green spaces to intercept rainwater from the Source.Implement the suitable practical rainwater management technology with LID in Kunming. Combine engineering and artful design in management.
