Abstract: Zhejiang province owns abundant tourism resources which help make it one of China’s most developed provinces in tourism. However, many tourism resources are partly or completely destroyed due to aimless development and utilization. It is suggested in this paper that the quality of tourism activity be promoted, scientific estimation system for bearing capacity be established, the order of nature and pristine state of tourism resources be attached more importance than economic development so that the sustainable development of tourism resource and tourism economy can be guaranteed.

Abstract: Based on index system of mining area ecosystem management is set on, on the basis of ecosystem health in mining area, constructs the ecological environment in mining area level, management of mineral resources, mining area economic and social development level as the criterion layer multi-level evaluation index system of index of quantitative method, combined with the change trend of volatility and changes in indicators of the direction and speed, puts forward the trend function and grey prediction method is applied to dynamic evaluation model of mining area ecosystem management, and in a certain mining area, the inspection case study conclusion shows that the mining area ecological system management is in medium level, need to strengthen management, and proposed the corresponding countermeasure and the suggestion.

Abstract: Numerical models have been commonly used to study solute transport behaviours both in laboratory-and field-scale cases. However, numerical interpretation and predictions of solute transport are complicated by various uncertainties and therefore can be misleading and lead to incorrect understanding of solute transport behaviours in hydrogeological systems. Such uncertainties have been discussed with a case study of radionuclides transport at a potential site for disposal of Low-and Intermediate-Level radioactive Wastes (LILW) in southern China. Firstly, pre-modelling assumptions cause uncertainties for model performance and have a significant influence on the model output. Therefore, such assumptions and related factors should be thoroughly considered and minimized in laboratory experiments or investigated in the field. Secondly, difference in the calculated plumes caused by uncertainties in the development of conceptual models suggests that the hydrogeological conceptual model should be developed based on intrinsic understanding of the transport problems and relevant data collection. Thirdly, relative sensitivity (RS) has been calculated to analyse the parameter uncertainties. Results indicate that the uncertainties are tracer-, parameter-and time-dependent. Therefore, model uncertainties arising from parameters should be considered for each specific parameter with the specific period. Finally, prediction scenarios are associated with uncertainties in the model prediction stage. Results suggest that the uncertainties in scenarios of future transport conditions should be recognized prior to model prediction. This study illustrates some of the uncertainties that might affect numerical transport models and therefore will be a useful reference for application of solute transport models to assessment of contamination risks from a LILW disposal site.

Abstract: The hazards of debris flows and the vulnerability to these flows were used as a basis for risk assessment in Zhouqu County, southern Gansu Province, China. The GIS software was used to perform a regional risk assessment for each township in Zhouqu County with a 250 m×250 m spatial resolution. The vulnerability of the population, the economy, and the ecological environment were accounted to develop a comprehensive vulnerability index for each township. A risk assessment model was used to develop a risk zoning map for Zhouqu County. It is found that the areas with the highest risk were mainly distributed in Chengguan, Dongshan, Jiangpan, Dachuan, and Guoye townships. Based on the results of the study, the recommendations for disaster prevention and mitigation were proposed.

Abstract: This paper elaborates the structure succession, hierarchical charicteristic and function of lake basin social ecological system (SES),combining “Pressure-State-Response”(PSR) with “Exposure-Resilience-Adaptability” model,based on “Analytic Hierarchy Process” (AHP) for driver analysis, from risk (pressure), sensitivity, adaptability builds the analytical framwork of social ecological system vulnerability. The results show that lake basin social ecological system is a complicated giant system, which contains several subsystem and there exists the cross-scale association in structure and process among systems with different scales .The structure of lake basinis in constant succession, and different stage of which has different function structure and cross-scale interaction. Resilience, adaptability, transformability of lake basin social ecological system are the result of the interaction of pressure on the system and their sensitivity to it. The evaluation index system could consist of three element layers: risk (pressure), sensitivity, adaptability, the interaction among whch decide the vulnerabilities of the whole social and ecological system.

Abstract: Tianjin Harbor Economic Area is one of the important functional areas of Tianjin Binhai New Area. At present, its artificial wetland ecological construction has started running. In this paper, the comprehensive benefits of artificial ecological wetland are analyzed in terms of ecological, social, economic. Including the industrial park wastewater treatment, water conservation, increase biodiversity, promote regional low-carbon development, beautify the landscape of industrial parks, produce the best possible results of ecological publicity and education function and promote regional economic development. The analysis showed that the artificial ecological wetland in Tianjin Harbor Economic Area has broad application prospects for such large-scale industrial parks, and it can be used as demonstration to promote ecological industrial park construction.

Abstract: The study simulates the changes of the population spatial distribution at three periods (daytime of workdays, daytime of non-workdays, and night) in 2012 in Dagushan peninsula of Dalian Development Zone on the ground of change in land use, based on the multi-temporal visual interpretation of remote sensing and GIS spatial analysis techniques. It establishes the individual risk contours and societal risk F-N curves in different periods of Dalian Qihua area according to risk prediction model, and then reveals the dynamic changing mechanism of regional environmental risk.

Abstract: The ecological security of the piedmont area has been a focus in the research of mountain ecosystem. However, with the development of the urbanization, the research of mountain ecological security under the impact of human activities, especially in the city which near the mountain, the research of protection and development of piedmont area seems not updated enough. Therefore, this paper selected Northern slope of Qinling Mountains in Xi’an, and made tourism activities the major driving factor for ecological security of tourism environment in piedmont area, thus establishing an ecological security evaluation system of piedmont tourism environment, based on DPSIR Model. The result showed that tourism development would enhance the ecological security level of regional tourism environment, and tourism activities would exert positive impact on regional tourism environment. The conclusions include: (1) Before 2007, the tourist environment of Huxian had been in an unsafe state, but in 2013, the ecological security level was largely raised; (2)The tourism ecological security in Chang’an is higher than that in Huxian District, and the ecological security level had already got into the safe state level
