中文摘要
        黄土高原是古代中华文明的发祥地, 由于气候变化和人类活动干扰, 该区水土流失严重, 生态环境脆弱。土壤水是黄土高原植被建设与生态恢复的重要资源, 土壤水问题的未来发展趋势对黄土高原生态文明建设具有极其重要的影响。文章从黄土高原气候变化趋势、退耕还林还草工程建设成效及其引发的土壤干燥化问题等方面, 讨论了当前黄土高原生态文明建设中资源与环境面临的突出问题。重点分析了土壤干燥化的概念、特征、环境效应及其调控等研究进展, 在此基础上提出黄土高原土壤干燥化问题的未来研究方向和面向生态文明建设的土壤水资源管理策略与目标, 以期为国家及黄土高原生态建设决策提供科学依据。
英文摘要
        The construction of ecological civilization is of great importance to human being's well-being and a nation's future. The Loess Plateau, the cradle of ancient Chinese civilization, is suffering from severe soil erosion and frail eco-environment caused by the climate change and human activities. Soil water is an essential resource to the vegetation construction and ecological restoration of the Plateau. The condition and future development of soil water is vital to the ecological civilization construction on the Plateau. This paper discusses the prominent resource and environment problems in the ecological civilization construction on the Plateau, focusing on the aspects of the trends in climatic change, the achievement of the"Green-for-Green"projects, and the consequent soil desiccation, etc. It analyzes the studies on soil desiccation, including its definition and characteristics, its impact on eco-environment, and the regulation measures. Based on the analyses, a proposal is made for the prospective studies of the Plateau soil desiccation, soil water resource management strategies and goals for ecological civilization. It aims to provide scientific basis for policies on the national and the Loess Plateau ecological construction.
