BP神经网络在生态系统服务功能中的应用

Application of BP Neural Network in Ecosystem Service Function

选取苏州市为研究地区,在生态系统服务价值评价方法的基础上,根据具体状况对苏州市的当量因子数值进行修改,确定土地利用类型中不同的服务功能的价值。并将其作为网络学习的样本,然后建立BP神经网络,通过模型来研究土地利用类别的生态服务功能在时空上的演变规律。

Suzhou is selected as the research area.On the basis of the ecosystem service value evaluation method,the equivalent factor value of Suzhou was modified according to the specific situation to determine the value of different service functions in the land use type.By using it as a sample of network learning,a BP neural network was established to study the temporal and spatial evolution of the ecological function value of land use categories through models.
