Thermokarst lake is a significant indicator of permafrost degradation. However, the evaluation of thermokarst lake development is very difficult through physical mechanism analysis because the development is influenced by many factors. In the present study, the factors influencing thermokarst lake development were investigated from the perspective of frozen soil and the geographical environment. The influences of six factors on thermokarst lake development in Beiluhe basin, located in the hinterland of the Qinghai–Tibet Plateau, were analyzed: permafrost type, ground temperature, vegetation type, soil type, hydrogeological type, and slope. Sensitivity coefficients were calculated for these factors using statistical methods. The results show that thermokarst lake development was influenced by the analyzed factors as follows: permafrost > soil type > ground temperature > hydrogeological type. Furthermore, 80.1% of the study area was highly sensitive to thermokarst lake development. Overall, thermokarst lake development in the Beiluhe basin was thoroughly evaluated based on sensitivity factors and an established statistical evaluation method. The method detailed in this paper provides a reference for evaluating the likelihood and severity of thermokarst lake development. 相似文献

Sedimentary records are potential to provide long-term evidence for better understanding the development mechanism of coastal hypoxia, shedding some light on the forecast, prediction and controlling-measure development to mitigate hypoxia. Therefore, recent research advances in the formation mechanism and evolution history of coastal hypoxia were briefly reviewed, specially with focus on sedimentary records and proxy methods. First, marine environments with hypoxia were classified into semi-enclosed marginal sea/gulf and open shelf sea based on the degree of bottom-water circulation and ventilation, and main characteristics for the hypoxic development were discussed respectively. Secondly, the methodology was reviewed in the efficiency by using different proxies to reconstruct hypoxia development history from sediment cores, including redox indicators of sedimentology, biology, mineralogy and geochemistry. Ultimately, recent research advance in hypoxic development mechanism and evolution history off the Changjiang Estuary were summarized. It is worth noting that long-term evolution history has been less studied from long cores. It is therefore suggested that a synthetic methodology involving multi-core comparison with different-proxy interpretation should be employed to study the development history of seasonal hypoxia off the Changjiang Estuary. 相似文献

The need for a sustainable approach in tourism development is very often addressed among the academia, the authorities and the stakeholders, as well as the apparent need for tools, which will guide the decision environment in evaluation and planning. This research aims to identify conservation and compatible areas for tourism development in Johor Ramsar sites, using spatial modeling in geographic information system (GIS). The study describes a methodological approach based on the integrated use of GIS and multi criteria decision evaluation (MCE) to identify nature conservation and development priorities among the wetland areas. A set of criteria was defined to evaluate wetland biodiversity conservation and development. Having defined the criteria, the next step was selecting suitable indicators and variables to measure the selected criteria. Subsequently the criteria were evaluated from conservation and tourism development point of view. These criteria were then weighted using the pair wise comparison technique of MCE and the results were integrated into GIS. Several conservation scenarios were generated so as to simulate different evaluation perspectives. The scenarios were then compared to highlight the most feasible and to propose a conservation and development strategy for the wetland areas. The generation and comparison of conservation and development scenarios highlighted the critical issues of the decision problem. This study represents an important contribution to effective decision-making because it allows one to gradually narrow down a problem. 相似文献

Studying the influence of shale gas exploration and development on groundwater environment is the basis of guiding water environment protection in the process of shale gas exploration and development.Groundwater environmental pollution is concealed,complex and persistent.Once it is difficult to control the pollution,the current commercial shale gas development zones in Sichuan Basin that are mostly located in karst areas and highly sensitive to groundwater will be vulnerable to the impact of shale gas exploration and development.Based on the hydrogeological conditions of shale gas exploration and development area and combined with engineering analysis of exploration and development,various risk pathways that may affect the groundwater environment during process of shale gas exploration,mining well construction,mining operations and other stages were identified in this paper.Some existing risk pathways were proved by verification of typical areas and should not be ignored.Based on the actual situation of typical areas,the countermeasures of groundwater environmental protection in the process of shale gas exploration and development in karst areas were discussed.It is believed that the groundwater environment can be better protected by strengthening administration,research and application of new technologies,precise design,hydrogeological conditions,and research and feedback of groundwater environmental protection. 相似文献
