标题： Soil carbon model Yasso07 graphical user interface

摘要： 在本文中，我们介绍了一种用于碎屑分解和土壤碳模型Yasso07的图形用户界面软件，并概述了该软件所基于的基本原理和公式。 该软件可用于测试模型并在简单应用中使用。 Yasso07适用于全球不同生态系统的高地土壤，因为它使用涵盖了全球气候条件并代表各种生态系统类型的数据进行开发。 作为输入信息，Yasso07需要关于碎屑输入到土壤、气候条件以及如果有土地利用变化的数据。 模型预测以概率密度形式给出，表示模型参数值和输入数据中的不确定性——用户界面使用内置的蒙特卡洛模拟计算这些密度。 显示英文摘要

摘要： In this article, we present a graphical user interface software for the litter decomposition and soil carbon model Yasso07 and an overview of the principles and formulae it is based on. The software can be used to test the model and use it in simple applications. Yasso07 is applicable to upland soils of different ecosystems worldwide, because it has been developed using data covering the global climate conditions and representing various ecosystem types. As input information, Yasso07 requires data on litter input to soil, climate conditions, and land-use change if any. The model predictions are given as probability densities representing the uncertainties in the parameter values of the model and those in the input data - the user interface calculates these densities using a built-in Monte Carlo simulation.
