土壤退化对湿地植被布局的影响建模研究——以野鸭湖公园为例
|
摘要
以往土壤退化对湿地植被布局的影响建模分析通常只针对一种人为干扰模式,对于多重干扰模式下的建模分析效果较差,针对该问题,设计多重干扰模式下的影响模型构建。以野鸭湖公园为例研究土壤退化特征,并在不同人为干扰下分析湿地植被布局情况。采用Field Spec 3背式野外高光谱辐射仪,对土壤退化造成的湿地植被布局影响光谱特征量进行采集。通过光谱平滑去燥、剔除水汽吸收波段以及光谱曲线均值处理等步骤,完成数据预处理。依据湿地植被生长危害破坏趋势,构建土壤退化特征下的湿地植被布局被影响模型,并进行修订。通过实例分析结果可知,该模型分析效果较好,为湿地植被保护提供技术支持。
In the past, the impact of soil degradation on wetland vegetation distribution was usually modeled and analyzed only for human disturbance mode, but the effect of modeling and analysis under multiple disturbance mode was poor. To solve this problem, the impact model under multiple disturbance mode was designed. Taking Yeyahu Park as an example, the characteristics of soil degradation were studied, and the distribution of wetland vegetation was analyzed under different human disturbances. Field Spec 3 backed hyperspectral radiometer was used to collect spectral characteristics of wetland vegetation distribution impacted by soil degradation. Data pre-treatment was completed by spectral smoothing, removing water vapor absorption band and spectral curve mean processing. According to the destructive trend of wetland vegetation growth hazards, the impact model of wetland vegetation distribution under the characteristics of soil degradation was constructed and revised. The results of case analysis show that the model has a good effect and provides technical support for wetland vegetation protection.
