Temporal and Spatial Changes of Rural Settlements and Their Influencing Factors in Northeast China from 2000 to 2020

Rural settlements in Northeast China have undergone significant changes the process of rapid urbanization, which has profoundly affected food production and sustainable rural development. Based on multi-period remote sensing interpretation data land use economic statistics, this study quantitatively analyzes temporal spatial pattern change characteristics influential factors from 2000 to 2020. The results show that: (i) Between 2020, area increased by 190,603.03 hectares, accounts for 7.62% total area, 129 counties (cities) (70.88%) settlements; (ii) expanded state presents a low distribution northwest high southeast. core density value north decreases, southeast increases slightly. In addition, landscape settlement expansion is irregular there was disturbance expansion; (iii) A 81.6% occupied comes cultivated land. soil’s organic matter content 10.0 g/kg–20.0 g/kg, high-quality 218,274.17 hectares. However, it interesting that coincides with increasing number hollow villages. From utilization degree decreased 56.97%; (v) main affecting are water resource conditions, terrain traffic location, level county areas superior agricultural influence various more obvious.
