基于SOFM方法的安徽省矿产资源开发主体功能区划研究

Research on major function oriented zoning of mineral resources development in Anhui Province based on SOFM

文章选择安徽省主要的矿产资源分布区,构建矿产资源开发功能区划指标体系,并通过自组织特征映射(self-organizing feature map,SOFM)网络方法对指标数据进行聚类,根据各聚类结果的区域特征,对安徽省矿产资源开发功能区进行研究。结果表明:安徽省矿产资源分布显著集中,矿产资源富集区主要分布在皖江及皖北地区;安徽省整体生态环境较好,研究区内80.77%的县区生态环境适宜进行适度开发;矿产资源较丰富的县区内生态环境适宜开发,而生态环境指数较高的县区矿产资源匮乏,表明安徽省矿产资源开发与生态保护不存在根本冲突。研究结果解释了安徽省矿产资源空间分布规律,可为分区制定差别化管理政策提供理论依据,对安徽省矿产资源可持续发展规划有一定的参考价值。

This paper selects the main distribution areas of mineral resources in Anhui Province,constructs the index system of functional zoning of mineral resources development,clusters the index data by self-organizing feature map(SOFM),and studies the functional zones of mineral resources development in Anhui Province according to the regional characteristics of each clustering result.The results show that the distribution of mineral resources in Anhui Province is significantly concentrated,and the mineral resource-rich areas are mainly distributed in Wanjiang and northern Anhui Province.The overall ecological environment of Anhui Province is great,and 80.77%of the ecological environment in counties in the study area are suitable for appropriate development.The ecological environment in counties with rich mineral resources is suitable for development,while the mineral resources in counties with high ecological environment index are scarce,indicating that there is no fundamental conflict between mineral resources development and ecological protection in Anhui Province.The major function oriented zoning of mineral resources not only explains the spatial distribution law of mineral resources in Anhui Province,provides theoretical basis for zoning and formulating differentiated management policies,but also has a certain reference value for the planning of sustainable development of mineral resources in Anhui Province.
