所谓持续发展就是人们通过对科学技术和社会组织进行管理和改善,开辟时间和空间上社会与资源相协调的发展,其核心是生态与经济的协调发展。水土保持是防治水土流失,保护、改良与合理利用山丘区、丘陵区和风沙区水土资源、维护和提高土地生产力,以利于充分发挥水土资源的经济与社会效益。我国是世界上水土流失最为严重的国家之一。水土流失给生态环境、社会经济发展和人类生存造成严重威胁,因此防治水土流失、改善生态环境是实现人与自然协调和资源—环境—社会经济可持续发展的根本保障。
The so-called sustainable development is the development of people through the management and improvement of science and technology and social organizations, opening up the coordination of society and resources in time and space. Its core is the coordinated development of ecology and economy. Soil and water conservation is to prevent and control soil and water loss, protect, improve and make rational use of land and water resources in mountainous areas, hilly areas and windy and sandy areas, and to maintain and enhance land productivity in order to give full play to the economic and social benefits of land and water resources. Our country is one of the countries with the most serious soil erosion in the world. Soil and water loss poses a serious threat to the ecological environment, social and economic development and human existence. Therefore, preventing and controlling soil and water loss and improving the ecological environment are the fundamental guarantees for the coordinated development of man and nature and the sustainable development of resources, environment and social economy.
