摘要

摘要：200多年来，土壤侵蚀一直被认为是美国的一个重要环境问题。已经进行了许多尝试来预测和量化这一现象，但仍然存在阻碍此类模型准确性和有效性的重大问题。本文描述了新一代部队流电侵蚀和沉积（USPED）模型的应用，该模型估计了夏威夷斯科菲尔德兵营（一个现役陆军训练设施）的土壤侵蚀和伴随的沉积物沉积。该模型85%的时间（60个随机分配点中的51个）将土壤侵蚀和沉积物沉积的建模估计准确地放在正确的视觉确定类别中。虽然不完美，但USPED模型估计值超过了80%的预定精度阈值，认识到模型估计值代表长期估计值，而视觉估计值主要基于相对较新的条件。

Validation of the USPED Erosion and Deposition Model at Schofield Barracks, O‘ahu, Hawai‘i

Abstract: Soil erosion has been recognized as a significant environmental issue in the United States for over 200 years. Numerous attempts have been made to predict and quantify the phenomenon, yet significant issues remain that hinder the accuracy and effectiveness of such models. This article describes the application of the new generation Unit Stream Power Erosion and Deposition (USPED) model that estimates soil erosion and concomitant sediment deposition at Schofield Barracks, Hawai‘i, an active Army training installation. The model accurately placed modeled estimates of soil erosion and sediment deposition in the correct visually determined category 85% the time (51 of 60 randomly assigned points). While not perfect, the USPED model estimates exceeded a predetermined accuracy threshold of 80%, recognizing that model estimates represent long-term estimates while visual estimates are based primarily on relatively recent conditions.

期刊介绍： Pacific Science: A Quarterly Devoted to the Biological and Physical Sciences of the Pacific Region The official journal of the Pacific Science Association. Appearing quarterly since 1947, Pacific Science is an international, multidisciplinary journal reporting research on the biological and physical sciences of the Pacific basin. It focuses on biogeography, ecology, evolution, geology and volcanology, oceanography, paleontology, and systematics. In addition to publishing original research, the journal features review articles providing a synthesis of current knowledge.
