The established models considered the spatial heteroge- neity of emissions sources, emission impact on the receiving waters, and the abatement cost. Empirical Keywords: estimates in Jiulong River Watershed of China indicated that a 30% reduction of the nitrogen load to the minimum cost solution receiving waters can be achieved by abating about 29% of total nitrogen emission and at a cost of RMB nitrogen reductions 263 million per year. Reduced applications of fertilizers and livestock holdings were the main abatement spatial heterogeneity Jiulong River Watershed measures, and the urban sub-basins the main abatement regions due to their high abatement capacity. It was necessary to specify a target water body located in the middle or upstream of the watershed to capture the local damage of excessive nitrogen emission although this will generates a high cost and a high reduction. -

Modelling Agricultural Nitrogen Contributions to the Jiulong River Estuary and Coastal Water
中国科技论文在线 http://www.paper.edu.cn Global and Planetary Change 47 (2005) 111–121 www.elsevier.com/locate/gloplacha Modelling agricultural nitrogen contributions to the Jiulong River estuary and coastal water Wenzhi Cao*, Huasheng Hong, Shiping Yue Key Laboratory of Marine Environmental Science, Ministry of Education, Environmental Science Research Centre, Xiamen University, Xiamen, Fujian 361005, China Received 23 February 2004; accepted 29 October 2004 Abstract The geographical setting of the Jiulong River estuary determines that the estuary receives wastes from both riverine input and adjacent urban sewage. However, the dominant nitrogen (N) source remains unclear. A nutrient mass-balance model and a preliminary LOICZ (Land–Ocean Interactions in the Coastal Zone) biogeochemical model were linked to evaluate agricultural N contributions from the Jiulong River catchment to the estuary and coastal water. Results showed that agricultural N surplus was the largest N source in the catchment, contributing 60.87% of the total Nitrogen (N) and 68.63% of the dissolved inorganic nitrogen (DIN). Household wastes and other sources followed. Riverine DIN fluxes were about 20.3% of exportable DIN and 14.4% of exportable total N, but approximately 9.7% of DIN inputs, and 7.3% of total N inputs to the Jiulong River catchment. The model system clearly showed that agricultural and anthropogenic activities in the catchment were the major N sources of the estuary and coastal water, and riverine N fluxes from these sources substantially impacted the estuary and coastal water quality and biogeochemical processes.

Study on the Quality Improvement of Anxi Tea Manor from the Perspective of All-For-One Tourism
The First International Symposium on Economics, Management, and Sustainable Development (EMSD 2019) Study on the Quality Improvement of Anxi Tea Manor from the Perspective of All-for-one Tourism Yongqiang Ma 1,2, a, Jingxuan Liang 1,2, b 1Anxi College of Tea Science, Fujian Agriculture and Forestry University, Quanzhou, Fujian 362400, China; 2The Center of Tea Industrial Development Research in Fujian Province, Fuzhou, Fujian 350002, China. [email protected], [email protected] Keywords: All-for-one tourism; tea manor; service quality; IPA model. Abstract: Tea Manor is a new type of comprehensive leisure industry integrating tea planting, production, marketing, culture, tourism and scientific research. However, during the development of cultural experience projects, due to local natural economic constraints, infrastructure construction, tourism enterprise services and tourist personnel services have encountered relatively large difficulties. How to effectively improve the quality of tea manor tourism services is crucial in the context of all-for-one tourism. In view of this, this paper uses the IPA model, combined with the actual situation of the service quality of Anxi Tea Manor, to study and analyze the tourism service quality of Anxi Tea Manor in three dimensions including Public infrastructure service, Corporate service and Traveling attendant services. 1. Introduction The development of society and the improvement of people's living standards, tourism is becoming a new way of leisure and relaxation for more and more people. Up to now, China has formed a domestic tourism market of 4 billion people, and the inbound and outbound tourism market has more than 250 million person-times. It can be said that the tourism industry has played a leading role in the development of various fields. -

Average concentrations of individual U isotopes are (3.23±0.14) μg/kg for 238U, (2.34±0.09)×10–2 μg/kg for 235U and (2.05±0.07)×10–4 μg/kg for 234U. Correspondingly, the U isotopic compositions are 155±18 for δ234U and 138±2 for 238U:235U. The U concentrations and isotopic ratios in the Taiwan Strait are similar to those of open ocean seawater, suggesting the dominance of the open ocean input to the strait’s U pool. -

The results show that the urbanisation level of the county areas in Fujian Province would be significantly increased if the urban characteristics resulting from in situ urbanisation were fully reflected, suggesting that the conventional urban statistics seriously underestimate the true extent of rural-urban transformation in the county areas. Furthermore, such underestimation is more serious in the coastal areas with most dynamic socioeconomic development, and thus distorts the true picture of the spatial pattern of rural-urban transformation.
