- Abstract
Water shortage is very serious in kunming area. Based on the precipitation and evaporation data of 2001-2011 of Kunming provided by Yunnan Meteorological Bureau, the article analyzes the change features of annual, seasonal and monthly rainfall and evaporation over the last 11 years. What's more, by referring to the calculation method of utilization potential of rainwater resources, it estimates the amount of rainwater resources utilization in Kunming area. The results show that the average annual evaporation in Kunming area is higher than that of average annual rainfall, so there are almost no rainwater resources available. But the average rainfall is more than the average evaporation in some months; this part of rainwater resource has the utilization potential. Usually the calculation methods for rainwater resources will take rainfall, evaporation, runoff, infiltration and landscape water replenishment and other factors into account on basis of water balance. This paper can also find the existing problems based on the data comparison of rainfall and evaporation in Kunming, and estimate the utilization potential of rainwater resource. It has great significance for using the urban rainwater to alleviate pressure on urban water consumption. What's more, this analysis aims to provide reference for rainwater management strategy and the design of park green space in Kunming area
