Abstract
Abstract. The Yangtze River Delta and North China Plain are experiencing serious land subsidence development and are also the areas that have undergone the fastest urbanization. Rapid urban development inevitably requires more water resources. However, China is a country with small per capita water resources, nonuniform distribution of water resources, and over-exploitation of groundwater – all of which are critical factors contributing to the potential for a land subsidence disaster. In addition, land subsidence has brought about elevation loss, damaged buildings, decreased safety of rail transit projects, lowered land value, and other huge economic losses and potential safety hazards in China. In this paper, Beijing, a typical northern Chinese city deficient in water, is taken as an example to explore (a) the problems of urban development, utilization of water resources, and land subsidence development; (b) the harm and influence of land subsidence hazards on urban construction; and (c) the relationship between urban development and land subsidence. Based on the results, the author has predicted the trend of urban development and land subsidence in Beijing and puts forward her viewpoints and suggestions.
Highlights
Since the 20th century, the issue of land subsidence attracted increasing, global attention in the urban development and construction industries
The monitoring and study of land subsidence disasters in China began in the 1920s, and revealed that the distribution and development of subsidence is largely influenced by urban construction (Zhang and Wei, 2005)
It is representative of other cities in North China that are deficient in water
Summary
Since the 20th century, the issue of land subsidence attracted increasing, global attention in the urban development and construction industries. This attention has continued to the present, and a lot of work has been done in monitoring and studying land subsidence disasters and their prevention (Zhang and Yang, 2010). The capital of China, is representative of the Chinese cities that have the fastest rates of land subsidence development in the country. It is representative of other cities in North China that are deficient in water.
