Dynamic Ice-Induced Responses of Offshore Fixed Platforms

The dynamic responses of offshore fixed platforms under ice loads are analysed in this paper. The responses calculated include the displacement and the hot spot stresses on the basis of a dynamic equation of ice-induced forced vibration for offshore structures. The results obtained can be cited and used for the design and operation of offshore fixed platforms against ice loading.     

中国对虾养成期细菌性黑鳃,褐斑综合症的病原生物学研究

本文是对中国对虾黑鳃、褐斑综合症进行病原菌分离和人工感染试验的报告。经细菌学鉴定表明,分离菌分别为海弧菌Vibrio pelagius Baumann和溶藻弧菌Vibrio alginolyticus sakazaki。人工感染试验显示,海弧菌是引起对虾黑鳃、褐斑综合症的主要病原菌,溶藻弧菌的合并感染导致对虾败血死亡。此外还应用电子显微镜对分离纯化的病原细菌进行了超微结构观察。

论风景名胜区内旅游开发建设项目的环境影响评价

风景名胜区旅游资源必须实行保护性开发，在风景名胜区内的旅游开发建设项目环境影响评价工作，应根据风景名胜区较为独特的自然和社会环境状况，全面并有重点地对旅游开发建设项目所带来的环境影响进行分析预测，有针对性地提出切实可行并行之有效的环境保护措施。螺丝壳山风景名胜区旅游开发项目的环境影响评价，应遵循这些原则。     

Development,Land-use Change and Rural Resettlement Capacity: a case study of the Three Gorges Project,China

Resettlement of people displaced by dam projects is an important development issue. Land lost due to the Three Gorges reservoir inundation and the adjustment of land-use policy in China resulted in land-use changes, and impacted on the human carrying capacity of the land and the land availability for resettlement. The Chinese government has implemented a ‘development-oriented resettlement’ policy and a ‘near resettlement’ approach to relocating rural dwellers affected by the Three Gorges Project (TGP). Based on recent land-use survey and population data of the case study area and using GIS-based multi-criteria analysis in land-use planning, this study analyses the characteristics and changes of land use in both the inundation and resettlement areas. Undeveloped land is scarce in both areas. The non-flooded cultivated land is distributed mainly on steep slopes (over 25 degrees). There is a discrepancy between the amount of land required by those being resettled and what is available in the designated resettlement communities. This study suggests that resettlement should consider the human carrying capacity of the land and, from a community standpoint, sheds light on the interplay between land-use planning and resettlement, and provides constructive suggestions for TGP resettlement strategies.     

山东省胶东半岛两次疑难历史地震的考证

山东省的胶东半岛历史悠久,是我国文化发展较早的地区之一。根据有关史料的记载,该区曾发生过１０４６年,４９５年虞丘山两次历史地震。但在确定地震参数时,由于历史原因,对史料中记载的“虞丘山”的位置说法不一,因而,对这两次地震的震中位置和震级存在不同的意见。

SUSPENDING VILLAGE" A MODEL OF NEW DEVELOPMENT AREA IN THE NINGXIA HUI AUTONOMOUS REGION OF CHINA

The southern part of the Ningxia Hui Autonomous Region in China was infamous for its poverty and serious soil erosion caused by over population. In order to alleviate poverty and backwardness, a plan was worked out: to remove 200,000 people to the north plain by developing newly irrigated land during the period of 1983-1992. The plan has been in operation for eight and half years to date. About 200,000 people have been removed from the poor southern part to the newly developed area, and 800,000 mu (1/ 15 ha) of desert land has been cultivated. Most of the migrants have been lifted out of poverty and the people's life in the south is being improved. During the immigration process, a model, called "Suspending Village", has been developed. In the article, the whole process of the development and the strategies are discussed.
