本文是根据一个较大的案例研究结果编写而成的。该研究调查了旅游和其它的人口流动在造成印度果阿地区沿岸生态系统变化中的作用。特别重点研究了当地被称为 “克赞”(khazan)土地和沙丘的农业生态系统,以及如何被转化来适应旅游者和旅游业的需要。本文还评估了不同形式的旅游业对土地覆盖和土地利用变化的影响。研究结果表明,引起生态系统变化的不仅仅只是人口流动,而且还有人与生态系统关系的变化。这意味着有些情况下土地覆盖变化没有像土地利用变化那样大,其它情况下土地覆盖的变化则十分巨大。影响土地利用和土地覆盖变化的因素还有立法、政治和经济方面的,特别是财产权的变化。
This article is based on a larger case study. The study investigated the role of tourism and other population movements in creating ecosystem changes along the coast of Goa, India. Special emphasis has been placed on the agricultural ecosystems of the area known as “khazan” land and sand dunes and how they have been transformed to suit the needs of tourists and tourism. The paper also assesses the impact of different forms of tourism on land cover and land-use change. The results show that the changes that cause ecosystem change are not only the population mobility but also the changes of human and ecosystem relations. This means that in some cases land cover changes are not as large as land-use changes and in other cases land cover changes can be quite large. Factors affecting land use and land cover change include legislative, political and economic changes, especially changes in property rights.
