| 摘 要： | 通过华北自然资源综合区划及动态变化的研究,能够详细掌握该区自然资源分布规律和演变趋势,为自然资源统一管理和决策提供技术支撑。在前人划分出的华北草耕自然资源大区基础上,遴选森林、草原、湿地和水资源等陆表自然资源分类以及与之密切相关的地形地貌、气候等要素指标,利用网格赋值法,开展1990—2018年综合区划工作,划分出11个二级自然资源亚区 和18个三级自然资源地区,并在此基础上分析了华北草耕自然资源大区的自然资源分布和动态变化特征,得出: 1990—2018年南部自然资源亚区自然资源主要变化情况是耕地转换为建设用地; 北部一些亚区自然资源主要的变化情况是草地转换为森林、耕地和荒漠等。华北草耕自然资源大区的进一步区划对自然资源精细化管理和华北地区典型区域自然资源动态变化特征的掌握具有重要意义。

| Abstract: | The study on the dynamic change of comprehensive regionalization of natural resources in North China can help researchers grasp the distribution law and evolution trend of natural resources in detail and provide technical support for the unified management and decision-making of natural resources. Based on the previous regionalization of grassland and cultivated land region in North China, the authors in this paper have selected the land surface natural resource classifications of forest, grassland, wetland, water resources and the closely related factors such as topography and climate, and adopted the grid assignment method to divide the 1990-2018 comprehensive regionalization into 11 secondary natural resource sub-regions and 18 tertiary natural resource regions. Besides, the distribution and dynamic changes of the grassland and cultivated land region natural resources in North China were analyzed on this basis. The results show that the main change of natural resources in the southern sub-region is the conversion of cultivated land to construction land from 1990 to 2018, while the main change of the some northern sub-regions is the conversion of grassland to forest, cultivated land, and desert. The further regionalization of natural resource region in North China is of great significance to the fine management of natural resources and the grasp of the dynamic characteristics of natural resources in typical regions in North China. |
