Abstract

Soil erosion, as a type of land degradation, affects various human economic interests. It is shown that the most promising areas of erosion studies where economic methods can be applied are assessment of actual damage from soil erosion, determination of the amount of probable damage from erosion processes in soils, and economic analysis in the development of sustainable land use systems for areas with soils subject to erosion. The group of methods for determining economic damage, including those which take into account ecosystem services that soils “lose” as a result of erosion processes, is characterized by the greatest development. Methods for assessing the risk of soil erosion have a significant development potential, since an extensive database of predictive models and equations (USLE, RUSLE, RUSLE-2, WEPP, EUROSE, CREAMS, EPIC, VNIIZiZPE, etc.) has been created, which make it possible to assess indicators of soil erosion in the future. Sustainable land use systems are developed using the neoclassical capital theory, which requires that the fertility of soil and net social benefits from nonmarket goods and services from agricultural lands should be maintained over time. Thus, it is possible to create compensatory taxation mechanisms for areas with the manifestation of soil erosion processes.

侵蚀土壤的经济评估:现状与发展前景
摘要 水土流失作为土地退化的一种类型,影响着人类的各种经济利益。研究表明,在水土流失研究中,最有希望应用经济方法的领域是评估土壤侵蚀造成的实际损失、确定土壤侵蚀过程可能造成的损失量,以及在土壤受侵蚀地区开发可持续土地利用系统时进行经济分析。确定经济损失的方法,包括那些考虑到土壤因侵蚀过程而 "失去 "的生态系统服务的方法,发展最为迅速。评估土壤侵蚀风险的方法具有很大的发展潜力,因为已经建立了一个广泛的预测模型和方程数据库(USLE、RUSLE、RUSLE-2、WEPP、EUROSE、CREAMS、EPIC、VNIIZiZPE 等),这使得评估未来土壤侵蚀指标成为可能。可持续土地利用系统是利用新古典资本理论开发的,该理论要求长期保持土壤肥力以及农田非市场产品和服务所带来的净社会效益。因此,可以为土壤侵蚀过程明显的地区建立补偿性税收机制。
