水土保持新理论

New Theory of Soil and Water Conservation

摘要: 经过多年努力，水土保持工作取得了重大进展，但是由于缺乏科学理论指导，每年因水土流失造成数以百亿生命财产损失，严重影响人们日常生活和经济社会高质量发展。为此，在多年创新研究基础上，作者提出了水土保持新理论。它包括：1) 水土流失是水土资源的迁移过程；2) 水土流失对经济社会高质量发展有负面影响和正面影响。新时期水土保持要开阔视野、全面充分认识水土流失后果，扬长避短，全方位高质量开展水土保持工作；3) 水土保持就是采用一些方法和措施，减少水土流失到土壤允许流失量水平，同时提高流失过程中水土资源的经济效益；4)实行水土保持高质量可持续管理，持续获取最大水土保持效能，满足人们对美好生活的向往对水土保持的需要。水土保持新理论的提出，极大地提高了水土保持科技水平，应用该理论地区都取得满意效果。

Abstract: China attaches great importance to soil and water conservation. Over the years, significant progress has been made in soil and water conservation. However, due to the lack of scientific theoretical guidance, tens of billions of lives and property losses are caused by soil and water loss every year, which seriously affects people’s daily life and high-quality economic and social development. Based on many years of innovative research on soil and water conservation, the author puts forward a new theory of soil and water conservation, which includes: 1) The process of soil and water loss is the migration of soil and water resources; 2) Soil erosion has a negative and positive impact on the high-quality development of economy and society. In the new era, soil and water conservation should broaden our horizons, fully understand the consequences of soil and water loss, develop strengths and avoid weaknesses, and carry out soil and water conservation work in an all-round and high-quality way. 3) Water and soil conservation is to adopt some methods and measures to reduce water and soil loss to the allowable level of soil loss, and improve the economic benefits of water and soil resources in the process of water and soil resources loss, and try to improve the efficiency of water and soil conservation. 4) Carrying out high quality and sustainable management of water and soil conservation to get the maximum effect of water and soil conservation and meet people’s need for water and soil conservation. The new theory of soil and water conservation has greatly improved the scientific and technological level of soil and water conservation. The application of this theory has achieved satisfactory results in all regions.
