环京津冀北贫困带土地利用/覆被变化研究
- Title:
- Study on Land Use/Land Cover Change in the Northern Poverty Belt of Hebei Province around Beijing and Tianjin

- 摘要:
- 运用地理信息系统空间分析技术、数理统计分析方法及景观生态学方法分析了环京津冀北贫困带1985—2000年土地利用变化的时空格局和演进态势，以期为冀北贫困带实现土地资源可持续利用和社会经济可持续发展科学决策提供依据。结果表明：1985—2000年，冀北贫困带林地和城乡工矿居民用地面积大幅度增加，耕地、草地、水域、未利用地大面积减少。增加的林地主要来源于草地和耕地，新增城乡工矿居民用地主要来源于耕地，未利用地主要转化为草地和耕地。土地利用多样性程度和破碎度降低，聚集度增加。耕地破碎程度增加，但形状趋于规整。其它土地类型均向规则、连片方向发展。
- Abstract:
- Supported by geographical information system(GIS) technology, statistical method, and landscape ecological methods, this paper analyzed the temporal and spatial change of land use during 1985—2000 in the northern poverty belt of Hebei Province around Beijing and Tianjin in order to provide scientific basis for sustainable development of this study area. The results show that forestland and urban-rural construction land significantly increased, while arable land, grassland, water body, and unused land decreased during 1985—2000. The increased forestland mainly originated from grassland and arable land, newly increased urban-rural construction mainly derived from arable land, unused land was mainly transferred into grassland and arable land. The diversity and fragmentation index of land use in the study area reduced, while aggregation index of land use increased. The fragmentation index of arable land increased, but its form tended to be regular. All other land use types tended to be more regular and contiguous.
