TL;DR: In this paper, a case study was conducted to understand the long-term effect of sewage irrigation on heavy metal concentrations in soil and plants, and the results showed that sewage irrigated soil contained much higher concentrations of Cd, Cu, Pb, Zn, Ni, Cr, As and Hg compared to clean water irrigation soil.

TL;DR: Wang et al. as mentioned in this paper reviewed the current status of wetland resources and the impact factors of degradation were discussed, and some key recommendations for improving wetland protection and management for China were given, including: improve special laws and regulations regarding wetlands, establish specialized management agencies; strengthen wetlands research and monitoring; and enhance public wetland conservation awareness.

TL;DR: Zhang et al. as mentioned in this paper analyzed the coastal reclamation status of China from 1979 to 2014 and analyzed its driving factors for mitigating negative ecological effects, including loss of marine habitats and deterioration of coastal water quality.

TL;DR: Wang et al. as discussed by the authors used a top-down approach to measure the national tourism dioxide emissions combining the Tourism Satellite Account and the Input-Output model from productive industry. And they found that the total carbon emissions of the Chinese tourism industry in 2002, 2005, 2007 and 2010 were 111.49m, 141.88m, 169.76m, and 208.4m respectively, accounting for 2.489%, 2.425, 2.439% and 2.447% respectively of the total CO2 emissions of all industries in China.

TL;DR: The results showed that the concentration and fluxes of CO2, CH4 and N2O were seasonally variable and the three GHGs emission fluxes in two sewage draining rivers of Tianjin were clearly higher than those of other rivers (natural rivers) and the spatial variation of CH4 was more obvious than the others.
