据统计北方土石山区水土流失面积高达13.49万km2,虽然轻度侵蚀的水蚀面积约为95%,但水土流失仍然是生态环境的主要问题。水土流失不仅制约着北方土石上去的经济的可持续性发展,还严重影响着下游地区的生态安全与水资源安全。加强区域的水土保持与搞好生态建设密切相关,也是区域经济发展的必要保证。从土石山区的自然特征出发,以陕西省为例,借鉴一些地区对土石山区沟壑的治理、水土的保持,在新的时代背景之下结合当前实际情况,有针对性地进行分析以便与同行更好地交流。
According to the statistics, the soil erosion in the mountainous area of northern China is as high as 134,900 km2. Although the water erosion area under mild erosion is about 95%, soil erosion is still the major problem of ecological environment. Soil and water loss not only restricts the sustainable development of the economy in the north, but also seriously affects the ecological safety and water resources safety in the downstream areas. Strengthening soil and water conservation in the region is closely related to improving ecological construction and is also a necessary guarantee for regional economic development. Based on the natural characteristics of rocky and mountainous areas and taking Shaanxi Province as an example, this paper draws lessons from the management of the ravines and the conservation of soil and water in some mountainous areas in some regions and analyzes them in a new context with the current situation in order to analyze more Good communication.
