As a dominant ecological stress factor of climate change, soil drought has become key challenge restricting food security. Based on moisture data, this paper uses the cumulative anomaly method, coefficient variation, Sen + Mann–Kendall trend analysis, and center gravity shift model to study spatiotemporal changes in Hebei Province from 2001 2020 optimal parameter geographic detector analyze factors affecting drought. The results show following: (1) over past 20 years, shown “first intensifying then easing”, experiencing two turning points, its spatial distribution showed significant agglomeration characteristics. (2) Soil single-peak seasonal fluctuation, with severe January May, peak June August, balance September October, deficit intensified winter. (3) stability differentiation, being high northeast low southwest. about 70% region improved, drought-prone areas moved (4) NDVI altitude are main drivers multi-factor interaction shows nonlinear enhancement effect. Among them, thresholds such as > 0.512 −32~16 m have inhibitory effect This can make contribution improving water resource management increasing agricultural productivity region.

Global challenges such as climate change, ecological imbalance, and resource scarcity are closely related with land-use change. Arid land, which is 41% of the global land area, has fragile ecology limited water resources. To ensure food security, resilience, sustainable use resources, there a need for multi-scenario analysis change in arid regions. carry this out, multiple spatial techniques indicators were used to analyze typical inland river basin Northwest China—the Tailan River Basin (TRB). Then, PLUS model was analyze, certain time period (1980–2060), same basin. The scenarios included Natural Increase Scenario (NIS), Food Security (FSS), Economic Development (EDS), Water Protection (WPS), Ecological (EPS), Balanced Eco-economy (BES). results show that 1980–2020, TRB mainly driven by changes cultivated grassland, forest built-up land. For period, substantial increase (865.56 km2) significant decrease (197.44 grassland (773.55 study area.
