环境发展,是国际社会关注的重大问题。21世纪生态危机成为人类面临的最大威胁,森林作为陆地生态系统的主体,自然成为世人瞩目的焦点。由于中国西部水土流失、土地沙化、水资源紧张、生物多样性锐减等问题越来越突出,给人民的生活与国民经济发展造成巨大损失。退耕还林成为中华民族生存与发展的根本大计,这不仅关系到当代人的生存与发展,而且关系到子孙后代的生存与发展。
Environmental development is a major issue of concern to the international community. The ecological crisis in the 21st century has become the greatest threat to mankind. As the main body of the terrestrial ecosystem, the forest has naturally become the focus of world attention. Due to the problems of water and soil loss in western China, desertification of land, shortage of water resources and sharp reduction of biodiversity, the problems of people’s life and national economic development are greatly damaged. Returning farmland to forests has become the fundamental plan for the survival and development of the Chinese nation. This not only concerns the survival and development of the present generation, but also the survival and development of future generations.
