西部生态建设是全国的生态安全屏障

West Department Ecological Construction is the Ecological Safe Protective Screen of Nation-wide

西部生态环境建设是事关国家的安全和社会的可持续发展,它是属于全国性的公共产品。特别是西部的青藏高原有"地球第三极"之称,是世界上独特的生态环境地域单元。是我国乃至南亚、东南亚地区的"江河源"和"生态源",更是亚洲乃至北半球气候变化的"启动器和调节器",是我国重要生态屏障和安全屏障,其丰富的动植物资源,对我国科学研究与经济发展有其特殊的生态战略地位。在西部生态重建中,中央政府近年来也不断加大了投入,生态环境有所好转,但西部生态环境是一项长期的战略任务,关系到国家安全,其生态效益远远大于经济效益。因此,在市场经济条件下,如何使生态效益和社会效益达到最大化,这就要从整体利益考虑生态这种纯公共产品问题。在重建中要继续加大投入,实施纵向与横向的利益补偿机制,达到在市场经济条件下的公平性。才能使生态公共产品效益与效率达到最大化。实现西部生态公共产品与经济社会的可持续发展。
