摘要
土地与能源资源是社会经济发展的重要基础。能源开发区土地质量受开发活动影响较大,构建全面系统的土地质量监测体系对区域可持续发展十分重要。文中以鄂尔多斯为研究区,从野外监测网络布设的典型性、代表性和经济可行性要求出发,参考农用地质量等别变化监测、水土保持监测、生态监测等相关研究,结合区域能源开发现状,构建干旱半干旱能源开发区土地质量野外监测网络。根据研究区地形地貌、土壤、气候、水文等方面特征划定了7个监测控制区;在监测控制区下,依据能源开发矿区分布以及矿区规模选择出7个监测样区;在监测样区内,依据土地利用类型选择114个监测样点。文中在鄂尔多斯所构建的监测控制区-监测样区-监测样点多尺度结合的土地质量野外监测网络,为获取土地质量监测数据,促进区域土地可持续利用提供了坚实基础。
Land and energy resources are the important foundations for social and economic development. The land quality in energy development zones is greatly affected by mining activities. Therefore, establishing a comprehensive and systematic land quality monitoring system is very important for regional sustainable development. By taking Ordos as the research area, referring to research on monitoring of agricultural land quality, soil and water conservation monitoring, and ecological environment, and considering the current situation of energy development, this research established a field monitoring network for land quality in arid and semi-arid energy development zones on basis of typicality, representativeness, and economic feasibility requirements of field monitoring network deployment. According to the characteristics of topography, soil, climate, and hydrology, Ordos is divided into 7 monitoring control areas. In monitoring control areas, 7 monitoring sample areas are selected according to the distribution and scale of mining areas. 114 monitoring samples are selected according to the land use types in monitoring sample areas. This research constructs a multi-scale land quality field monitoring network, according to the order of monitoring control areas-monitoring sample areas-monitoring samples in Ordos, which can provide a solid foundation for obtaining land quality monitoring data and promoting sustainable land use.
