Cropland use is experiencing an intense transition in both depth and breadth with rapid development of the Chinese economy. Unwarranted land use transitions can affect the ecosystem services value (ESV) and ecosystem functions significantly. This paper reports the dynamic patterns of cropland transition (CLT) and its impact on ESV in Jiangsu Province based on land-use data from 1990, 2000, 2010, and...
In recent years, several strong earthquakes occurred in China, like the 2008 Wenchuan Earthquake, 2003 Bachu Earthquake, etc. These earthquakes triggered numerous flow failures, causing severe damage to buildings and infrastructure. In this paper, some general characteristics of flow failures triggered by these recent earthquakes are reviewed. Based on seismic data analysis and field investigation,...
Constructed wetlands (CWs) have proven to be a promising treatment alternative for developing countries. Recently attention has been focused on the ability of CWs to reduce human pathogens in wastewater. In this study, indicator microorganisms (Escherichia coli) and pathogens (Salmonellae) were analyzed from a full-scale surface flow constructed wetland situated in China. The results showed that for...
In China, as hermetic automated equipments have not been used in so large a scale that the cement conveying mainly depends on cement porters. Cement porters often work in dusty circumstances with very high labor intensities. So it is necessary to develop cement porter's protective clothing by improving the current cement workers' clothing, to satisfy the requirements on work movements and environmental...
China is largely affected by marine disasters because of her long coastal line, and storm surge is the most of all. The loss of storm surge disaster annually reaches tens of billion RMB. With the change of focus from disaster reduction (DR) to disaster risk reduction (DRR), risk reduction is paid more attentions and it is gradually considered as an important step in real disaster mitigation activity...
Removal efficiency and distribution of six kinds of indicator and pathogenic microorganisms in a full scale constructed wetlands in China were analyzed, and die-off rates of the indicator and pathogenic microorganisms in the water and the sediment of the constructed wetlands were determined. The results showed that the constructed wetlands could effectively reduce Escherichia coli by 99.9%, fecal...
