区域生态环境综合信息图谱的分类与案例分析——以福建省为例

生态环境图谱类型的划分是自然资源合理开发利用和治理及地学信息图谱研究的基础。该文采用系统分析的思路,在总结对比分析前人对土地利用/土地覆被、植被、地貌、景观以及生态环境等的分类研究的基础上,依据地学信息图谱的方法论,借助遥感和地理信息系统等技术,构建生态环境综合信息图谱分类的系统,并以福建省为例,提出福建省生态环境图谱的分类系统。

Classification of the Comprehensive Informatic TuPu for the Region's Eco-environment: A Case Study on Fujian Province

The classification of eco-environmental TuPu underpins the rational development and treatment of natural resources and the research of geo-information TuPu.Taking systematic analysis as its train of thought,this paper is designed to set up a classification system of comprehensive eco-environmental information TuPu,on the basis of the summary and contrast analysis of land use by the predecessors and the classification studies of land cover,vegetations,landforms,landscape and eco-environment etc.,in the light of methodology of geo-informatic TuPu and with the aid of the technique of RS and GIS.As the elements of basic geographical structure,landforms and wide range of temperature conditions are natural bases that can’t be changed on a large scale by mankind under present technical conditions.The regional disparities of these factors make different environment occupy a certain regional space.Thus,it’s imperial to first distinguish different environment districts and to consider,on the basis of which,the functions of nature and human elements in an all-round way.Namely,the comprehensive functions of water and heat factors determine the main categories of macro ecosystem such as forest,grassland,desert,etc.Human activities further check the advance directions of natural ecosystem.Therefore,the first-level classification is made according to the vegetations and land use conditions.The second one is made in line with eco-environmental problems caused by human beings and exploitation methods used by mankind.Finally,it comes up with the classification system of eco-environmental TuPu,taking Fujian Province as an example.
