生态区边界智能识别模型构建分析

Intelligent Recognition Model of the Ecoregion Boundary

大量生态分区研究资料表明,对生态区边界的智能识别、自动分区是生态格局与过程、生态系统服务功能等生态环境研究内容的关键。本文基于专家知识经验和生态分区原则,以地理信息系统为建模平台,运用栅格生成技术,对生态区边界智能识别模型进行机理探讨和框架构建。生态区边界的自动识别和生态区的自动分区,旨在克服目前生态区边界确定过程中的精度低、周期长、更新难等诸多问题。这对数字生态建设也有重要的现实意义。

Lots of investigation data about the ecological zone show that how to well and truly achieve the intelligent recognition of the ecoregion boundary and automatically classify the ecological zones is the key issue in the researches of ecological structure, ecological process, and ecosystem service function. On the basis of specialist experience and principle of ecological zones, the intelligent recognition model of ecoregion boundary is developed with the grid generation methods on the GIS platform. The model overcomes the limitations in the ecological zone methods at present, these limitations include low precision, long period, and difficult to be updated etc. Furthermore, the model could intelligently recognize the ecoregion boundary and automatically classify the ecological zones.
