胜利油田滨二块双低单元综合治理方案及经济评价

在对胜利油田滨二块砂二段油藏的地质特征、注采井网、开发现状进行精细研究的基础上，科学分析了单元双低（采油速度低、采出程度低）的主要原因，提出了一套技术先进的双低治理方案，采用“增量法”进行经济评价表明，该方案不仅技术可行，而且具有较好的经济效益，是低产老油田恢复能力的好办法。     

对有偿转让集体荒山使用权的思考

有偿转让集体荒山使用权，是农村继家庭联产承包责任制后的又一次生产关系的变革，也是农村传统土地管理制度突破性的改革探索。有偿转让荒山使用权是手段，治理绿化和开发利用荒山资源及促进农村经济发展是目的。本文就其在实践上取得的效应、理论上突破的客观性和需进一步完善的政策三个方面作了思考性阐述。

The Development and Positioning of Business Related University Tourism Education

Abstract

The teaching of tourism at a higher education level has become well established in British universities, but in the UK, as elsewhere in the world, the place of tourism studies within the academic curricula remains uncertain. The paper considers the diversity and complexities of tourism studies through a categorisation of journal articles, and through an investigation of the underlying debates that have influenced the design of academic curricula in the UK. The paper concludes that tourism, at least at present, should not be regarded as discipline but as a field and that the most common approach in the UK has been to emphasise the business studies subjects. The University of Northumbria's established undergraduate travel and tourism management course is presented as a case study of this approach to the subject field.     

Devising an electronically supported heritage conservation method for the Valley of Flowers in the Indian Himalayas

The Valley of Flowers is a national park in the Himalayan state of Uttarakhand in India that was classified as a world natural heritage site in 1988. Around 1982, its maximum carrying capacity was fixed at 60 persons per day, which has been called excessive by experts and observers, given the extremely fragile and immensely valuable nature of the Valley's heritage. This, in monetary terms, can be put at millions of dollars, and is considerably more viewed in terms of knowledge of breeding medicinal plants in cold climates that are being affected by climate change, which its microclimate and ecology present. Given the state's poor resources and the fact that tourism is one of the most important industries for development and conservation, this research assesses the heritage value of the Valley and develops a programme for conservation, including a computerised program for permits, whose value can easily be raised from the current paltry Rs 150 per person. Accompanied by fallow periods and marketing through the Internet to aim for educated tourists, the program ensures that the maximum carrying capacity of the Valley is never exceeded, thus spreading out the number of tourists over its 3.5-month season, while allowing flexibility in booking for chance groups and small families that can pay more.
