Bank Collapse

Reservoir bank collapse results in vegetation destruction on bank, worsens soil - water loss, impacts local economic and environment. Therefore, attention should be attached to research of reservoir bank collapse mechanism and control measures. The impoundment and operation of China Three Gorges (CTG) reservoir largely changes hydrologic and geologic conditions of the reservoir bank, greatly influences the reservoir bank stability. On the base of summarizing the structure types of main bank and slope in the reservoir area, the typical bank collapse mode and mechanism in CTG reservoir area are analyzed, including erosion degradation type, sloughing type, sliding type and collapsing type. In the light of different material composition, correlative control and harnessing measures are put forward, which can be referred in the control and harnessing of bank collapse in the reservoir area.

Probability System

Ship oil spill accident will lead to enormous hazards in the Three Gorges Reservoir area. The risk mitigation of the ship oil spill is significant to the stakeholder of the maritime safety administration. To study the risk evolution of the ship oil spill in the Three Gorges Reservoir area, the framework of ship oil spill risk evolution was proposed according to the general definition of the risk; then, risk evolutions were analyzed from the perspectives of expected probability, system constraints of accident developing, and possible harmful consequences based on accidents analyses, simulation experiments, and structural equation model analysis. The results indicate that the system constraints of accident developing, such as the quantity of oil spills, free evolution time, and wind and flow conditions, have significant impacts on risk evolution of the ship oil spill after the occurrence of an accident in the Three Gorges Reservoir area.

Source Data

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.

Landscape Types

In recent years, soil degradation and decreasing orchard productivity in the sloping orchards of the Three Gorges Reservoir Area of China have received considerable attention both inside and outside the country. More studies pay attention to the effects of topography on soil property changes, but less research is conducted from the landscape. Therefore, understanding the effects of landscape positions and landscape types on soil properties and chlorophyll content of citrus in a sloping orchard is of great significance in this area. Our results showed that landscape positions and types had a significant effect on the soil properties and chlorophyll content of citrus. The lowest soil nutrient content was detected in the upper slope position and sloping land, while the highest exists at the footslope and terraces. The chlorophyll content of citrus in the middle and upper landscape position was significantly higher than the footslope. The redundancy analysis showed that the first two ordination axes together accounted for 81.32% of the total variation, which could be explained by the changes of soil total nitrogen, total phosphorus, total potassium, available nitrogen, available potassium, organic matter, pH, and chlorophyll content of the citrus. Overall, this study indicates the significant influence of landscape positions and types on soil properties and chlorophyll content of citrus. Further, this study provides a reference for the determination of targeted land management measures and orchard landscape design so that the soil quality and orchard yield can be improved, and finally, the sustainable development of agriculture and ecology can be realized.
