基于GIS和BP神经网络技术的建设用地适宜性评价研究

GIS and BPNN Based Construction Land Suitability Assessment

本文提出了在地理信息系统(GIS)和BP神经网络技术支持下,对建设用地适宜性进行评价的一种新方法。阐述了建设用地适宜性评价的评价原则与体系,并提出了新方法的技术路线。最后以珠海市横琴岛为研究实例,基于GIS平台,利用BP模型,对横琴岛建设用地的适宜性进行了评价。

This paper proposes a geographic information system （GIS） and BP neural net （BPNN） supported new method of assessing construction land suitability, describes the principle and system of the construction land suitability assessment, and puts forward the technical route of the new method. Taking Hengqing Island of Zhuhai municipality as a research example, based on GIS platform and using BP model, this paper conducts the suitability assessment of the construction land in Hengqing island.
