Abstract
本发明提供了一种流域保土增汇效能评估方法及系统，属于流域生态修复技术领域，该方法包括：基于目标流域，采集得到多源流域数据并进行预处理，通过将经预处理的多源流域数据整合至统一的地理数据库，得到整合地理数据库；构建土壤和水评估工具‑碳循环模块耦合模型，并根据整合地理数据库，通过仿真模拟得到耦合过程数据，并利用分层多变量联合约束策略进行率定和验证；构建保土增汇效能指标体系，根据经验证的耦合过程数据，对目标流域保土增汇效能进行综合评价，得到保土增汇效能指标并进行时空冷热点分析和决策支持，得到动态评估结果；本发明解决了现有流域保土增汇效能评估难以在统一框架下模拟水土碳耦合过程以及无法进行科学评估的问题。
