Managing Scarce Water Resources – China

Detection on Resources Consumption Drag of Urbanization in China

A unique model of resources consumption drag of urbanization is developed by employing the neo-classical production model and the urbanization relation model. By using this model, it is viable to estimate the resources consumption drag, measured as the reduced speed of urbanization from resources consumption and environmental services. In terms of reduced urbanization process, the aggregated an...

Scaling Law between Urban Electrical Consumption and Population in China

The relation between the household electrical consumption Y and population N for Chinese cities in 2006 has been investigated with the power law scaling form Y = A0N β . It is found that the Chinese cities should be divided into three categories characterized by different scaling exponent β. The first category, which includes the biggest and coastal cities of China, has the scaling exponent β >...

Mitigating Urban Wetland Impacts on Downstream Water Resources

Wetlands in older urban areas have often been integrated into stormwater management systems and exhibit severe degradation from receiving decades of untreated and uncontrolled urban runoff. Vegetative diversity is often poor and dominated by a few hardy species such as cattail (Typha latifolia) or reed canary grass (Phalaris arundinacea). These wetlands may also be affected by legacy impacts fr...
