摘要
水土流失是当今世界上自然灾害之一,中国水土流失日益严重,已成为制约社会经济发展的重要因素。近几十年来,尽管在水土保持方面做出了很大努力,取得了显著成就,但由于环境条件限制,水土流失仍呈加剧趋势,随着社会经济的高速发展,开发建设项目大面积扰动土地,形成新的水土流失,出现一方治理,多方破坏的现象,使水土流失状况呈现复杂化、多样化。及时、全面、准确地了解和掌握不同区域、不同尺度水土流失动态变化状况,了解国家水土保持和生态建设重点工程的进展和效益情况,是社会发展的现实需求,也是实现区域可持续发展,推动人与自然和谐共处的关键,有着非常积极的现实和长远意义。
Soil erosion is one of the natural disasters in the world.Soil erosion in China is becoming more and more serious,which has become an important factor restricting social and economic development.In recent decades,although great efforts have been made and remarkable achievements have been made in soil and water conservation,due to the limitation of environmental conditions,soil and water loss still shows an aggravating trend.With the rapid development of social economy,development and construction projects disturb land in a large area,forming new soil and water loss,and the phenomenon of one-party treatment and multi-party destruction appears,which complicates the situation of soil and water loss diversification.Timely,comprehensively and accurately understand and grasp the dynamic changes of soil and water loss in different regions and scales,and understand the progress and benefits of national key projects of soil and water conservation and ecological construction,which is not only the practical demand of social development,but also the key to realize regional sustainable development and promote the harmonious coexistence between man and nature,which has a very positive practical and long-term significance.
