基于GIS的城市绿地空属一体化信息库构建及维护的实用方法研究

准确实时的城市绿地资源信息数据库是绿地信息化和精细化管理的前提,但实际却面临空间信息延误、绿地属性信息缺失的难题,严重制约了绿地信息化管理的时效性和准确性。本文在分析城市绿地空间和结构的特点之上,基于GIS提出了一套城市绿地资源空属一体化信息库构建和维护的实用方法。研究基于GIS建立了一套空间信息获取和校核的方法流程,包括基于遥感的绿色信息提取方法、空间信息核准的校核单元、核准内容、核准方法等;提出了基于绿地分类的属性数据库构建的方法流程,包括数据库字段设计和调查方法等。该空属一体化的建库和维护方法能够为各地园林绿化的信息化管理提供实用的方法支撑,可以有效解决由于信息更新滞后带来的信息管理系统使用"夭折"问题。

Research on Practical Method of Construction and Maintenance of Urban Green Space Integrated Spatial Attribute Database Based on GIS

An accurate and real-time database of urban green space resource information is the premise of green land informatization and refined management.Still,it faces the problems of delayed spatial information and lack of green space attribute information,which severely restricts the timeliness and accuracy of green space information management.Based on the analysis of the characteristics of the space and structure of urban green space,this paper proposes a set of practical methods for the construction and maintenance of an integrated information collection of urban green space resources based on GIS.Based on GIS,a group of techniques for acquiring and checking spatial information established,including a method for extracting green information based on remote sensing,a verification unit for spatial information approval,approval content,and approval methods,and proposed the construction of an attribute database based on green space classification—method flow,including database field design and survey methods.The integrated approach of building and maintaining airspace can provide practical method support for the informatization management of landscaping in various places.It can effectively solve the problem of"deadness"in the use of information management systems caused by the delayed updating of information.
