黄河流域内蒙古段土地利用变化监测分析

In this paper, the study takes the Inner Mongolia section of the Yellow River Basin as the object, and based on multi-source data such as national land survey data, second and third surveys, constructs an analysis index system and statistical analysis evaluation model to monitor and analyze land use changes in the basin, flowing areas, beach areas, irrigation areas, dam areas, and key monitoring areas from 1999 to 2023. Research has found that the continuous expansion of construction land reflects population agglomeration and economic development needs, but also brings ecological pressure; There are significant regional differences in the dynamic degree of arable land, which are related to agricultural policies and economic structural adjustments, and it is necessary to balance production capacity and ecological protection; The dynamic degree of grassland utilization fluctuates greatly, affecting ecological stability and agricultural production; The trend of changes in water area varies, reflecting different needs for water resource management and development; The continuous expansion of transportation land promotes economic circulation, but there is a shortage of land resources. This study provides scientific basis for natural resource management decision-making and policy-making in the region, and helps promote regional sustainable development.
