| 摘 要： | 基于自然环境、地理以及自然资源研究进行自然资源综合区划,有利于充分认识和分析区域内自然资源环境状况以及动态演变规律,为自然资源调查监管、区域经济的可持续发展和规划提供决策依据。把环境地理要素和自然资源作为划分不同区域的基础和依据,进行自然资源综合区划,可以强化对区域自然资源的地域差异和动态变化特征的科学认识,对合理开发利用自然资源具有重要的指导意义。通过确定区划单元的主导划分要素和辅助决策要素,利用主成分分析法和聚类分析法,初步将研究区自然资源综合区划等级体系划分为3级,二级区划包括7个自然资源亚区,三级区划包括14个自然资源地区。对1990—2018年期间各级分区的自然资源时空动态特征开展定量分析后认为,在此期间,研究区主导资源总体变化趋势是森林资源减少、耕地资源大幅度增加,具体表现为森林转变为耕地、草原转变为耕地。

| Abstract: | Based on the study of natural environment, geography and natural resources, the comprehensive regionalization of natural resources is conducive to fully understanding and analyzing the internal natural resources environment status and its dynamic change, which could also provide some decision-making basis for the investigation and supervision of natural resources, the sustainable development and planning of regional economy. In this paper, the authors have adopted the environmental geographical elements and natural resources as the basis to divide different regions and carry out the comprehensive regionalization. The scientific understanding of regional differences and the dynamic change of natural resources could be strengthened through the comprehensive regionalization, which has important guiding significance for the rational development and utilization of natural resources. Through difining the dominant division and auxiliary decision-making elements of the regionalization units, the authors have used the principal component analysis and cluster analysis method to preliminarily divide the comprehensive regionalization of natural resources into three level system. The secondary regionalization includes seven natural resources subregions, while the tertiary regionalization includes 14 natural resources districts. Besides, the temporal and spatial dynamic characteristics for natural resources from 1990 to 2018 at all levels were also quantitatively analyzed. The results show that the overall change of the dominant resources is the decrease of forest resources and the significant increase of cultivated land resources. The specific changes is the transformation from forest to cultivated land and the transformation from grassland to cultivated land. |
