摘要
介绍了陇中黄土高原丘陵区的自然地理特点， 分析了其生态环境现状， 认为极端脆弱的生态环境和超负荷的人口对该地区构成了双重压力。提出水土保持与生态建设是实现整个地区可持续发展的基础和前提。深入分析了水土保持与生态建设中存在的问题及其主要原因。在实地调研与比较研究的基础上， 提出了陇中黄土高原丘陵区生态建设的发展方向， 即：（１） 树立可持续发展的生态建设指导思想；（２） 走建设水土保持型生态农业与发展小流域生态经济的生态建设之路； （３）
With a area of about 1.13×10 5 km 2 , Gansu loess plateau can be divided into two parts, west Gansu loess hill gully region and east Gansu loess plateau gully region from the physical geographical point of view. It is one of the most severe soil erosion areas of the loess plateau. The fragile ecology and overloaded population have entailed great pressure on this region. It has been proposed that soil and water conservation and ecological construction are the basis and safeguard for the sustainable development of the whole area. Based on analysing the existing problems and its main causes in soil and water conservation, and on the on the spot investigation and comparative study, we have put forward the orientation of ecological construction of Gansu loess plateau, that is, (1) foster the thought of sustainable developmental ecological construction; (2) take the ecological construction road of establishing eco agriculture of soil and water conservation pattern, and developing small watershed eco economy; (3) implement strategic systematic engineerings of ecological construction which can make peasants rich.
