- Abstract:
-
In order to explore the spatiotemporal evolution of land use function and its driving factors in the ecologically fragile areas of Gansu Province, taking the loess hilly area as an example, we used comprehensive evaluation methods, nuclear density estimation and geographic detectors are to reveal the dynamic evolution law, spatial characteristics and influencing factors of land use function in district and county units from 2009 to 2017 based on the perspective of land use multi-function. The results show that:(1)in 2009, the total land use function in the loess hilly area was improved in an orderly manner, but the overall level was not high, the ecological function declined slightly, the production and living functions improved rapidly, and the spatial differentiation was significant;(2)the land use function of the loess hilly area had obvious characteristics of regional differences, with a trend of further expansion and slight spatial polarization;(3)the spatiotemporal evolution of the land use multi-function in the loess hilly area was the result of the comprehensive effect of the regional natural resource endowment and socio-economic conditions, and the explanatory power of the total land use function after any two sub-functions interacts was enhanced. Based on the spatial and temporal characteristics and influencing factors of the land use multi-function function, the differentiated land use strategies should be formulated to scientifically allocate land resources, adjust land use methods, coordinate different functional relationships, improve the overall functional level of land use, and help optimize the spatial pattern of the country and improve the quality of land use.
