摘要:
用生态安全的PSR(压力-状态-响应)概念模型和层次分析法,建立了西藏曲松县生态安全评价体系,综合评价了曲松县生态安全现状.结果表明,当前曲松县生态安全状况处于预警状态,生态环境问题已成为制约当地经济发展和社会进步的主要因素.从气候变化、资源利用和人类经济活动的角度阐述造成这一严重生态环境问题的自然和社会根源,提出适合曲松县改善生态安全现状的主要途径.
Abstract:
Making use of PSR conceptual model of ecological security and hierarchy analysis method,evaluation system of ecological security of Qusum county,Tibet Autonomous Region is established.The results show that present ecological security in Qusum county is in a yellow alert state,eco-environmental problems become the main limiting factors for the local economic development.The natural and social origins of those eco-environmental problems are expounded from the point of climatic changes,resources exploitation and human activities,some available approaches are brought forward to improve the status of ecological security of Qusum county.
