In recent years, ecosystem service values (ESV) have attracted much attention. However, studies that use ecological sensitivity methods as a basis for predicting future urban expansion and thus analyzing spatial-temporal change of ESV are scarce in the region. In this study, we used the CA-Markov model to predict the 2030 urban expansion under ecological sensitivity in the Three Gorges Reservoir area based on multi-source data, estimations of ESV from 2000 to 2018 and predictions of ESV losses from 2018 to 2030. Research results: (i) In the concept of green development, the ecological sensitive zone has been identified in Three Gorges Reservoir area; it accounts for about 35.86% of the study area. (ii) It is predicted that the 2030 urban land will reach 211,412.51 ha by overlaying the ecological sensitive zone. (iii) The total ESV of Three Gorges Reservoir area showed an increasing trend from 2000 to 2018 with growth values of about USD 3644.26 million, but the ESVs of 16 districts were decreasing, with Dadukou and Jiangbei having the highest reductions. (iv) New urban land increases by 80,026.02 ha from 2018 to 2030. The overall ESV losses are about USD 268.75 million. Jiulongpo, Banan and Shapingba had the highest ESV losses.

Evaluation of ESV Change under Urban Expansion Based on Ecological Sensitivity: A Case Study of Three Gorges Reservoir Area in China

Effect of different carbon sources on methane production and the methanogenic communities in iron rich flooded paddy soil.

The Three Gorges Reservoir Area (TGRA) stretches along the Yangtze River from Jiangjin District, Chongqing to Yichang, Hubei in China. Since TGRA is the main source of drinking water and fresh fishery in China for millions of people, both researchers and the government have concerns for environmental pollution and ecological security in the TGRA. This review highlighted the status and trends of primary water pollutants/parameters in the TGRA and evaluates their impacts on its ecological health for nearly 12 years. In this study, we analyzed the published data including the bulletin on the ecological and environmental monitoring results of the three gorges project, statistical yearbook data from years 2004 to 2015 and published articles. Chemical indicators model was applied to elucidate the ecological health of TGRA based on nitrogenous compounds, phosphorus compounds, organic reducing substances, volatile phenol and heavy metals (Cr, Cd, Cu, Hg, As and Zn). The results showed that the ecological health conditions slightly varied during these years in the TGRA. Moreover, the value of ecological health in spring, summer and autumn was lower than that in winter. Generally, the overall ecological health of the TGRA during these 12 years seems to be stable. Although the ecological health of TGRA is good, there is an urgent need to strictly implement the industrial discharges standards to assure the ecological integrity and sustainable development of the TGRA.
