摘要
人类活动严重地改变了里海地区的生态系统,最主要的影响是引起了生态系统中水流的改变和水质的恶化。地区环境的改变已经影响到了这一地区经济的发展,对鱼类资源的影响尤其明显。专家们利用GIWA计划中得出的一套方法,对这一地区共享水域中最重要的跨边界问题进行了评估。本报告关注促使这一地区环境改变的最重要的根本原因:生境和生物群落的改变。
Ecosystems in the Caspian Sea region have been heavily modified by anthropogenic activities,mainly as a result of changes in the water flow and degradation of the water quality in the ecosystems.Changes in the regional environment have influenced regional economies,particularly obvious in the impacts on fish stocks. Using the methodology developed in the GIWA project,experts in the region carried out an assessment of the most important transboundary issues in shared waters in the region.This report focuses on the root causes for the most important drivers of environmental change in the region:habitat and community modification.
