Evaluation of Water Resource Carrying Capacity of Small Towns in the Rapid Urbanization Period in China

Abstract

With the acceleration of the urbanization process of the small town in China, the problem of shortage of the water resource has become evident, as a result, it is urgent to set up a system for monitoring and evaluation the water resource carrying capacity (WRCC) of these small towns and predicting the trends of the change of the WRCC in this rapid urbanization period according to the master plan of the town. By analysis the progress and problems of the previous research of the WRCC, this paper proposed a method: per-land water consumption method for monitoring the WRCC of the small town in the rapid urbanization period which can be cooperated with the 3S technology (RS, GIS, GPS) by surveying and calculating the average per land water consumption data of each water consumption unit in the small town. And based on the features of the water supply and consumption in the small town, this paper also proposed the index system and model for WRCC evaluation which is adaptable to the monitoring system. In the end, this paper takes Dongsheng town as a case for testing the reliability of the monitoring, evaluation and prediction system of the WRCC. And according to the result of the evaluation and prediction of the WRCC in Dongsheng town, the rationality of the master plan for 2020 has been tested and solutions are given to improve the WRCC in Dongsheng town.
