Economic Analysis of Invasive Species Risk Using A Spatial Integrated Model

入侵物种经常与本地物种竞争，造成各种经济和生态系统损失，如对农作物的损害。因此，有效的入侵物种管理是实现可持续发展社会的重要问题。一旦入侵物种入侵并建立，它们会随着时间的推移蔓延到邻近地区并造成长期损害。然而，用于控制其传播的适当管理可以减缓传播速度或至少暂时阻止其传播。因此，为了有效地控制其传播成本，有必要应用动态的空间管理分配问题框架。本文将管理分配模型与元胞自动机模型相结合，对入侵物种的扩散进行预测，寻求有效的管理策略，以减缓入侵物种的扩散。

Invasive species often compete with native species causing various economic and ecosystem loss such as damages to agricultural crops. Therefore, efficient and effective invasive species management is an important issue for achieving a sustainable society. Once invasive species invade and establish, they spread to neighboring areas over time and cause extended damages. However, an appropriate management for controlling their spread, can slow down the speed of spread or can stop their spreading at least temporally. Therefore, in order to control their spread cost efficiently, it is necessary to apply dynamic and spatial management allocation problem framework. We integrate management allocation model and a Cellular Automaton model that project the spread of invasive species and search for the efficient management strategy for mitigating the spread of invasive species.
