文峪河流域土地利用/覆被变化及其驱动力分析

摘  要：
土地利用/覆被变化对于区域的自然、经济和生态发展有着深刻的影响,土地变化驱动力研究是土地利用/覆被变化的核心问题之一。为了探讨中西部小流域的土地覆被变化特征及其驱动因子组成与驱动方式,以山西省文峪河流域为研究对象,基于RS与GIS平台,分析流域2000—2018年土地利用/覆被变化情况;利用马尔柯夫模型预测未来土地利用结构;选取自然因子、区位建设因子、社会经济因子,利用Logistic回归的建模方法分析流域的土地利用/覆被驱动力。结果表明,流域整体耕地、林地、草地面积有所减少,水域、建设用地、其他用地类型面积增加,不同地类的变化速度、土地转移情况不同,流域整体土地变化速度较快,利用程度提高,有序化程度下降,均匀度增加。预测结果显示,耕地、林地、草地、其他用地面积下降,水域、建设用地面积增加,除耕地、建设用地外,其余地类面积变化较小。自然因子、区位建设因子和社会经济因子对研究区土地利用/覆被变化都具有显著的驱动作用。流域的土地利用/覆被在过去18年间经历了快速、复杂的变化,自然因子对土地变化具有基础性、长远性的影响,短时间尺度上区位建设因子与社会经济因子是影响土地变化的主要驱动力量。

摘  要：
The driving force of land use/cover change which has a profound impact on the natural,economic and ecological development of the region is one of the core issues. In order to explore the characteristics of land cover change and its driving factors and modes in the small watershed of the central and western China, the land use/cover change of Wenyu River basin from 2000 to 2018 was analyzed based on RS and GIS,and the natural factors,location-construction factors,socio-economic factors were selected to analyze the driving force of land use/cover change by the Logistic regression modeling method.The results showed that the area of cultivated land,forest land and grassland in the basin decreased,while the area of wetland,construction land and other land types increased. The change speed and land transfer situation of different land types varied,and the overall land change speed of the basin was faster. The utilization degree increased,the orderly degree decreased,and the evenness increased. The prediction results showed that the area of cultivated land,forest land,grassland and other land decreased,while the area of wetland and construction land increased,and the area of other land types except cultivated land and construction land changed little. The natural factors,location-construction factors and socio-economic factors had significant driving effects on land use/cover change in the study area. There were rapid and complex changes of land use/cover in Wenyu River basin in the past 18 years. The natural factors had a fundamental and long-term impact on land change,while the location construction and socio-economic factors were the main driving forces affecting land change in a short time scale.
