GIS-Based Analysis on Evolution and Driving Forces of Land Desertification in Fengning County of Hebei Province
[Objective] To analyze the evolution and driving forces of land desertification in order to provide technical references for land desertification controlling and the rational exploitation and utilization of land resources in the Fengning County
Hebei Province.[Methods] Through remotely sensed imagery interpretation based on remote sensing and GIS
we analyzed the temporal and spatial evolution of regional land desertification and its driving factors in the Fengning County in 2009 and 2014.[Results] The desertification land showed an obviously regional distribution
which was mainly distributed in the fixed sandy land of the midwest areas. Over the past 5 years
the total area of desertification land generally decreased despite the moderate desertification area increased
in which the area of mild desertification decreased by 560.9 hm2
the area of severe desertification decreased by 1 872.6 hm2
and the total area of desertification land decreased by 809.2 hm2. The plateau was easier to form desertification than the lower hilly zone
the degree of desertification was more severe in the arid zone than that of semiarid zone.[Conclusion] Based on local landscapes and environmental conditions
Spatiotemporal variation trends and driving factors of fractional vegetation cover in Jiangsu Province from 2013 to 2022
