AI Technical Summary
Technical Problem
现有技术难以有效识别和评估城市林水复合生态系统的动态变化，特别是其非规律性淹水情景和季节性变化，无法满足城市生态规划和管理的需求。
Method used
By acquiring image data from both rainy and non-rainy seasons, vegetation and water indices are used to identify water bodies and forest land. Vegetation frequency, water frequency, and forest-water integration degree are calculated. The zero-model threshold assessment system is then used for classification, dividing the area into ecological integration zone, basic forest-water boundary zone, and water-forest zone to be restored.
Benefits of technology
实现了对城市林水复合生态区域的准确评估和分类，为城市生态系统的精细化管理提供科学依据，优化生态建设与管理。
